(8x) 2.5mm x 6mm Button Head Screws (for the lids), (2x) 2.5mm x 6mm Self Tapping Screws (for nodeMCU mounting), (4x) M3 x 6mm Countersunk Crews (for the motor mount). Close your blinds, dim the lights, and snuggle up for that new show you've been meaning to watch. If you are just a die-hard, hands-on, DIY kind of person and want to do this the hard, but less expensive way, you could always try out the instructions given in this lengthy guide on making your own smart blinds and setting them up yourself. You can actually go right to their website and create custom designs for each of your windows for the job. The best choice for you would be to use ESPHome . Thanks. Perhaps someone else could comment on this? It’s not really that hard to understand why people are so in love with the idea of having motorized blinds and shades for their rooms. Is your motor shaft rounded or kida truncated? Their blinds run off solar power, so there’s nothing to plug in. Done, I have emailed you the STL and also updated it in the product downloads. Have you looked up any guides on how to use it with Arduino and a Nema motor? How To Pump Up Your Party With Home Automation, Google Home and SmartThings : Everything You Need to Know. So I will do coding myself in ESPHome. Hi guys. The STL files should be available this weekend. Whats that sticking out of the side of our device? I have some YTDY 5×0.5 mm (0.196 mm2) left so I may try that. You can use different ones if you stay within the width and length dimensions. This will show you how to retrofit your existing blinds and really take you down a techie rabbit hole that I’m not prepared to get into here in this post. In this case why not just get the buck converter directly to 3.3V, so there is no need for the NodeMCU to convert 5V to 3.3V again. Which kind of limits your options, so it kind of is what it is from that perspective. Did you use JK35HY26-0284 ? Thanks. Hi, I am considering making a smart blind controller. Compatible with Alexa and Google Assistant enabled If you consider that the pull on the device is in the upward direction then the holes start to make sense. For this project I will use the NEMA 14 and NEMA 17 Stepper motor. Blind Engine claims that they work with roller shades, roman shades, horizontal blinds, vertical blinds, and roll type curtains. Would it be possible to create something for 5 mm beads in the future? Give this STL a go. Unfortunately I will not be releasing the source Fusion files. Hello. For anyone using the TMC2209 (probably the whole 22** family, but I can’t confirm as I only have 2209) instead of connecting D7 to sleep (as on the A4988), you connect it to EN, and you need to invert the logic for the pin, so where it’s HIGH it needs to be LOW and vice versa. I know there’s a trade-off with setting speed, but would love to tweak it and find the optimum for my setup. That way I would reduce the cost (less ESPs used), WiFi interference and hopefully some hassle. However, there’s a catch, you’ll need Ikea’s $30 Tradfri gateway installed on your network to integrate the blinds into your smart home. Mobile Control (can be controlled through your smartphone), Multiple Control (you can control multiple blinds simultaneously), Location Recognition Control (they can be set to go up or down based on your phone’s location). I’m wondering if It would be a problem… Probably I would need to glue cog into that or use some screw to fix it in place. I have estimated that the total cost of this project is between $40 AUD – $60 AUD depending on where you source your components. 8mm should be sufficient. I’m not familiar with editing STL files (tried that before) so it would be much helpful for me if you could prepare different versions of this project. Can you please specify which motor model should I buy? 2amps? But you probably have all kinds of questions, just like I did about what the best smart shades options are for your room. So, Iâve got a SmartThings V3 hub and Iâm using the non-classic SmartThings app on iOS. Smart blinds So, youâve got a bunch of old blinds in your home, and your considering purchasing something to upgrade them to smart blinds.But you probably have all kinds of questions, just like I did about what the best Tag: Smart Blinds (VIDEO) Smart Blinds December 10, 2013 / SmartThings / 1 Comment Inspired by an article on Makezine, a member of our developer community created a project to control his blinds using SmartThings. I can hear only ball chain rustling. Using beautiful design and innovative software, Gear is a smart device that lets you easily control and schedule when your shades open and close, making With the press of a button, you can slide these shades open or shut. I am keen to try this driver myself due to it being quieter. Thank you. and 3 motors with one module. That’s an interesting idea. Is it possible for you to prepare two additional STL files (design variants) with holes moved to the one and the other side of case? I’m already powering Sonoff camera (12V, 1A) that way. Please not the wiring in the schematic diagram. It’s small enough and together with the NODE MCU that should make the setup compact. Additional question: The blinds are very responsive, if I say “Alexa, close the living room blinds”, they start closing within a second or two. And But I wondered how much weight the NEMA 14 can handle before I order my parts. Thanks, that would be perfect! It comes with two different gears that can work with normal string cords, small ball chains, and large ball chains. I am very interested in the v3.0 project. Everything worked the first time around. Is My Amazon Echo Dead or Did It Just Stop Working? d7 -> Enable. Thank you everyone that participated in the survey. If the idea of installing something to make your existing blinds smart scares the crap out of you, then you might want to consider just purchasing and installing new smart blinds or having someone else install them for you. So I decided to make myself this DIY Arduino Curtain Automation system. I would usually setup a DHCP reservation so that the device does not change its IP when I use it with SmartThings or HomeBridge. I thought it might be the motor so I swapped it out for a different Nema 17 motor that I know works well, but I had the same result. Unfortunately I hit set back, I fried 3 of my WiFi NodeMCU and Wemos D1 boards thinking they can handle a 12v input – wrong! Unfortunately I don’t have any experience with Home Assistant. To power the circuit from one 12v power supply, a 12v to 5v Buck converter will be required. If you are integrating the DIY SmartBlinds with smartthings then you will need the SmartThings Hub. Taking into account filament shrinkage, when printed on my Prusa MK3 i3 printer, the result holes are about 2.2mm to 2.3mm. I want to try and keep this unit as small as possible. Their Smart Bridge works with Nest, SmartThings, Wink, Logitech Harmony, and Sonos. This should make this devices much stronger (based on estimated values from manufacturers specs, results may vary). You can (sorry, I’m really brand new to electronics!). Why my fourth try? You should now be able to first the Nema14’s you wanted to get. I have used the Node MCU ESP8266 processor for many of my projects. Great project so far. NEMA 14 has roughly the torque of 14N.cm (20oz.in.) wifi said: DIY-SmartBlinds I was going to find one online but if you have one that would be great. #define hotPIN D8. Obviously installing your own motorized blinds is a huge pain in the tuchus to install though and can get very expensive if you have a lot of windows that have blinds that you want to convert over. Then I thought it might just be that I had put it on a large window where the shade was too heavy. my case is 140x80x50 using 47x42x42 stepper motor which i had at the time. So you can safely use the chain to open the blinds. Once it connects, I find it on my home router in the DHCP list. Hi David, I am sure it’s possible to build a device that uses the GM4632-370 DC motor you listed and that has external buttons and LEDs for feedback. Full review of the iBlinds horizontal blinds controller. Can’t start my driver for now. Ah yes, thats a 100uF 16v capacitor, it’s meant to protect the circuit and stabilise the input voltage in case there are any fluctuations. The only thing that comes to mind is your limiter setting on the controller. However with one ESP you will need to run at least a 5 core wire between the devices. Thanks! Hi Filip, I am testing the 3D design now. Zemismart Updated Tuya zigbee Roller Blind Driver Built-in Battery DIY SmartThings Alexa Google Assistant Voice Control,Roller Shade Driver, Roller Sh - Tuya zigbee hub required if would like control by tuya, or alexa / Google home. Hi peter, been working with the Nema version of the smart blinds, about the hardware, yes a buck converter is needed to step down to 5v, i would go with the buck converter instead of a mosfet or similar, it runs safer and cooler. All with a simple voice command, schedule setting or tap on your phone. I will post on Github later and a link in the post. May be hardware problem? The issue I had is the software I tried to convert the code to the AccelStepper library with no luck, I believe AccelStepper library is one of the best out there to drive Nema steppers. I flash standart example but I have nothing. I’ve now sunk a lot of time into this project and really want to get it to work! It’s cool, but all I see is my power bill going up! Thoughts? Cick the blue link: March 8, 2017 - New Product Announcement I have been a part of the smartthings community for only about three months, and Iâve seen a lot of interesting ideas and devices. Nema17 would be 10x but its bulky. Thank you. what error is that? Ikea has come out with their own line of smart blinds and what’s nice is that Ikea’s Fyrtur and Kadrilj smart blinds are much cheaper than any other bought off the shelf, another nice plus is that they don’t require professional installation. Below is a short teaser of the project. Make sure you choose one that can handle a current of 1-2A as a stepper motor can be drain quite a bit of current per phase. Is it a particular voltage? I have a soft tested sketch for the NodeMCU that uses the AccelStepper library. The A4988 requires a minimum of 8v-35v for the motor but the circuit can be powered by 3.3v-5v. Hello, weâre looking to start purchasing some blinds and are wanting to motorize them to be compatible with Samsung Smartthings. I have a NodeMCU that overheats, yet if I replace the circuit with another it works cold. This site uses Akismet to reduce spam. This is my fourth and final code to control window blinds in SmartThings with a NodeMCU ESP8266 chip and a servo. Can you describe what exactly are you having a problem with? Thanks! Designed by Elegant Themes | Powered by WordPress, Review: Samsung SmartThings V3 Hub and New Sensors. Make sure you choose one that can handle a current of 1-2A as a stepper motor can be drain quite a bit of current per phase.”. Why Is Everyone Talking About Sonos Smart Speakers? I have never tried that. This processor has a smaller form factor and could also be a good choice. It really all depends on the number of windows you are covering and whether you are doing it yourself or not, but you can expect to pay anywhere between $35 – $150 per window that is receiving the smart motor blinds. [If you are using Homebridge and my accessory plugin, then you just replicate your settings changing the IP of the DIY SmartBlinds device in the accessory plugin. I’ve also discovered a smaller option for the ESP32 type board which seems dimensionally more akin to the Node MCU, so will give that a try. Drape size 1600 dropx1500 wide & 1600 drop x 2000wide. What wiring diagram should be? Thank you for posting. (The nodeMCU I use to control my garage currently gets a tad hot sometimes in its 3D printed box, and the Arduino Uno I had before that kept freezing in summer). Otherwise you just need to be patient and take it step by step. I’ve made my own case for now but look forward to yours when it’s ready. Blind Engine started off over on Kickstarter and has since become a well-respected brand within the smart home community. Yes, from memory I believe reducing the delay amount will increase the rotation speed. Is this something that could happen with a bad A4988? We love the automated privacy and energy savings they bring to our homes. They look absolutely gorgeous, also they The other thing I’m finding is that the screw holes are too small. Find the most basic Arduino sketch using the WiFiManager library and see if you can get your NodeMCU to connect. but I can’t see it im my wifi list on my iPhone. That’s it. The max amp of the controller is 2amp and you probably will not run it at full power? Using regular curtain blinds, I could control the amount of light in the room and suit it according to my needs. I’d like to get started but I am pretty new with Arduino – is there a specific driver board I would use with the Nema 14? The diameter of one “ball” was 4,5mm and the distance between the balls were like 6mm. I’m just not sure what I do now. Automated blinds are becoming more popular as the smart home market continues to grow. The stepper motor I’m using just clicks and doesn’t appear to have enough torque to actually move my roller blinds. The other downside is their compatibility in my opinion. I’ve just bought and downloaded your design but there’s still only one variant. Hi Peter, what’s the best way to increase the RPM? If you are using Homebridge and my accessory plugin, then you just replicate your settings changing the IP of the DIY SmartBlinds device in the accessory plugin. Thanks Peter will purchase stl files and use yours as a starter and see the options, many thanks for the reply. Is it through adjusting the delayMicroseconds argument? TMC2208 driver make blinds absolutely noiseless. Perhaps one of the raiders here could assist? I connect d5 -> step d6-> dir I’m worried opening by hand when the device is connected to the chain might cause strain and break it eventually. Looking SmartThings capable and integrated blinds or shades or any type of window treatment basically. Is 1Amp sufficient? SmartThings motorized blinds are the new-gen automatic blinds and shades that are controlled by remote system. If you want to check them out, you can go directly through Lutron’s website and see if it’s the right fit for you. Is there another option for this “bug”? #define sleepPIN D7 But A4988 driver is very loud. I found the Wemos a bit more finicky to get up and running than the ESP8266, but eventually it got running and I like having something smaller to work with.). So keep this in mind if you are considering purchasing them for your rooms. SmartThings uses the ZWAVE protocol and works well with our motorized blinds and shades. 00 10% coupon applied at $ . Hi Peter, just wondering what the specifications on that capacitor are as it’s not in your BOM? Other than mounting the device on the other side, you would probably need to modify the code and change the direction of the motor? It is a very interesting project. Hi Peter, so I finally got around to trying this out on my blinds but unfortunately it doesn’t work. 2.9N.cm. I was helping on a cable and internet set up in this guy’s $2.5 million dollar home. #define dirPIN D5 It should make blinds noiseless. Obviously, there are a whole lot of caveats to this question.

You can also integrate the SmartBlinds with Apple HomeKit but you will require a Homebridge (it’s another kind of hub that works with HomeKit) Once you have the SmartThings hub, you can also connect Alexa to it and operate the blinds vie voice. Required fields are marked *. I have just got my drapes sort of working. hi like the project do you think it would work with GM4632-370 DC 12V 30RPM High torque Turbo Encoder Motor Worm Geared Motor Reducer Motor, just I built 3 blind opening units and its ok but think yours is better and has HomeKit option, if it would work would it be easy to convert the code to use this motor. Took a few steps to get there but is perfectly how I wanted it now. NodeMCU is a better choice because it has VCC in pins. Iâve seen something like this while doing research but now i donât recall where. my setup is: TMC2208 (Still got it working on a A4988 driver), Wemos D1 mini and a NEMA 17 Motor. One of the big options that he wanted was to make sure that the blinds were automated so that he could look out at the mountains from his living room in New Hampshire when he was sitting in his home in Florida. Tried it at different angles and different levels of tension and nothing. Smart window blinds & shades communicate using Z-wave for integration with your Z-wave home automation system. Hope these help. In the design, the top and bottom holes are set to 2.5mm in diameter. Then I add my home wifi settings, said and pass and connect. This site also participates in other affiliate programs and is compensated for referring traffic and business to these companies. I had a go at designing this in Fusion 360 while waiting for your design just for fun (not as good as yours, but I got fairly close), and it got me thinking if it would be possible to add up/down/stop buttons and some sort of interrupt to the code to manually open/close the blinds with these? Actually I’ve just realized that sometimes I would need them on one side, and in other cases on the other. The best features of the Blind Engine are: The best part of these blinds for your windows, as far as I was concerned, was the 3-minute easy installation. Do I need a SmartThings hub for this to work? But at the ⦠[Config] Homebridge Config UI X v4.23.2 is listening on :: port 8581 The only difference is that they have built in motors which allow you to remotely raise and lower them. I wish I had the money to have two personal assistants and an “AV guy”, but I digress. The kit can only be used to retrofit 2- ⦠But everytime I close the blinds via Home-App I get a No Response Error in Home-App. Using regular curtain blinds, I could control the amount of light in the room and suit it according to my needs. So I picked up some DOIT ESP32 devkit v1 boards to use with this project – have already bought the STL files, but will need to do some ‘remixing’ to fit the bigger board as it’s a solid 9mm taller. Have you done any comparisons between the A4988 and TMC2208 in this respect? The E-Wand provides a simple, yet powerful, solution for automating venetian blinds, vertical blinds, or min-blinds. diysmarthomeguide.com is a participant in the Amazon.com Services LLC. The SmartThings home automation hub can use our shade and blind motors. The torque on my stepper motor doesn’t seem to be very powerful, is there anything settings wise that you think may help. The NEMA 14 motor is a smaller alternative to the NEMA 17 measuring at 35mm x 35mm x 26mm. Personally I don’t bother with voice control of the blinds, mine just open at sunrise and close at sunset. Since it’s receiving and processing commands I don’t think it’s the processor. Supercharge your workouts by making your environment work for you. Hope you understand what i mean , Your email address will not be published. If you are interested in checking out the reviews and current pricing you can find them over here on Amazon. There are only a couple of smart blind or window shade kits that I can really recommend to you at this point. Any one who want to use TMC2208 driver with this excellent project should change The biggest downside to these is the pain of installation compared to the Blind Engine. Thanks for the great instructions. Amazon is working on this and looks like a solution is coming soon. For roller blinds, I am not sure that the Nema14 will be strong enough. Oh, and I noticed that your model will probably suit only 3 mm string beads. Due to the walls on the main body being only 2.5mm thick, I found that when I printed it without the brim the model would get unstuck halfway through and the print was destroyed. Noiseless ;). So, you’ve got a bunch of old blinds in your home, and your considering purchasing something to upgrade them to smart blinds. I mean Arduino code. I then installed the Alexa-Homebridge plugin which made it controllable through my Alexa devices. Blind Engine’s max capacity is 10ft by 10ft and can hold up to 15lbs of weight. It would be much helpful for me. I’m just soldering the components together now so once I’m done I’ll create a video and post the link here so you can see. ⦠If you are integrating the DIY SmartBlinds with smartthings then you will need the SmartThings Hub. For me this cable worked well at a short distance of 5 meters. Speaking of enclosures, should the enclosure be similar to the design in V1 or more like V2? Hi Peter, This is a really awesome project and it’s great that it makes use of the NEMA as some of my blinds are quite heavy for the smaller steppers. Does anyone have experience with this? You’re right However, I will probably use ESPHome to control ESP8266 as I’m using Home Assistant solution for my smart home (those two integrate natively). I think the problem with library, because I even change router, did reset settings and still have nothing. There are two things though. As I see on this page https://github.com/tzapu/WiFiManager/blob/master/README.md I will update my post. DIY SmartBlinds v3 – Cog 5mm. You would need to modify the API as well such that you can send independent commands to each of your blinds. Can you provide some instructions on how to link it to Alexa please. Good luck. And when I run the unit without attaching it to anything it works great. But Now I can’t understand what is wrong. Maybe I need a higher-wattage PSU? Regarding the gap behind motor – that’s fine. When I attached it to my shade, though, it didn’t have nearly enough power to move the thing. You can add as many SmartBlind devices into the Homebridge setup as you want.]. So i was looking for a matching gear on thingiverse and modified it to match the Nema 17 motor. Hi Neil, I already have the SmartThings Device Handler built for the DIY SmartBlinds v1 & v2 from my website, You should be able to find the link here: DIY SmartBlinds v1 + SmartThings Device Handler. This site is owned and operated by Kevin Noyes. Something wrong. If you happen to be handy and donât mind a little DIY, the MySmartBlinds kit might be your best bet. But generally speaking installation for smart blinds cost will vary. I’m not in hurry, just asking out of curiosity. In general my printer is dimensionally accurate, but the screw holes aren’t anywhere near approaching 2.5mm. I can’t see any settings in the .ino file, Here are the library versions I used for this project if this helps: I designed it with a chain guard all inclosed. what I am to get is the blinds into home assistant as I run around 60 devices in HA. Perhaps you need to start from scratch. Hi Mikhail, I am not using D8, I will remove it from the code when cleaning up. My first problem was the gear…it didn´t match my chain. Absolutely great project! All are 77-inches (195-cm) long. I will need to order a few more and use a voltage regulator to drop the 12v to 5v to power the NodeMCU or WemosD1. My blind is 160 cm x 80 cm. Have you searched for issues relating to WiFiManager? This is perfect because it allows the 2.5mm screws to grip the plastic. Although, as with everything smart home-related, there are always new companies coming out with something innovative and better than what already exists. digitalWrite(sleepPIN,LOW); to HIGH Checkout the design renders and some first assembly photos below. Both of these come in at around the same price point. But still nothing. Sounds like to have a good lab setup for testing, you should also get a Nema17 Motor, these are rated at about double the torque of a Nema14, and see if that will operate the blind.
