It's surely more fun to flounder about with a project like this. The problem with eWeLink is that you are tied to the cloud to use it. All of this is fine if all you want to do is control a bought device controller. PD, Question Smart garage openers can save you a lot of anxiety. * Use at your own risk. All the other links seem correct. After you upload the software, power cycle the NodeMCU to restart it. It did a few things and it some of those few things well. on Step 5. I found the relay at Digi-Key and Mouser for < $3 but really long lead time.https://www.digikey.com/product-detail/en/omron-electronics-inc-emc-div/G6L-1P-DC3/Z1226-ND/413440. close a relay contact, run a servo, get data from a sensor, etc. There is no kickback diode in your circuit. I went looking for a solution myself and found a YouTube video that showed me how to modify a Sonoff Basic to do the job. There were a couple of skills that worked at one time, but Chamberlain ended up shutting them down. // Just remember not to delay too much here, this is a callback, exit as soon as possible. Most garage door openers have two terminals that when shorted by a simple push button will cause the garage door to open or close. [yoyotechKnows] built an Alexa-controlled garage door opener after his Liftmaster stopped working. The door controller assumes that the shorting will only be "momentary" and not permanent. The PROBLEM is the coil current of 60mA. Only 5ma to drive it at 3vdc. Answer Did you make this project? Is there any way to program this to work with it? That turns out to be a bit more complicated than I first thought. This is a solid state relay and as such has no coil. Yes, there's info out there that can help you most anything with Alexa. In my install, I only use my opener to close the garage door in the evening using a scheduled Alexa routine. Now, instead of turning around or leaving your garage and house vulnerable to thieves, you can check and close it with your phone with your choice of h… The routine runs at 9:00 PM every night and in order to ensure that the routine doesn't open an already closed garage door (the "Alexa enabled" opener doesn't know if the garage door is open or closed), I had to add one more switch that would only be closed when the garage door … Thx for the comment,P. If your internet goes down, so does your control of the device. ESP8266 NodeMCU microcontrollers are particularly well suited for IoT applications because of their extremely low power consumption, small size and very low cost. In my install, I only use my opener to close the garage door in the evening using a scheduled Alexa routine. If there already are wires attached to the opener terminals, make sure that you connect these wires in parallel with the existing wires. The devices that were "Alexa enabled" usually had an Android or iOS app so that you could control the devices from the app. I hadn't found this switch when I did the project but I probably would have done the project this way if for no other reason than to play with the NodeMcu. "Goodbye X10.". PD. The software that makes this device respond to Alexa is the included fauxmoESP.h module. Then compile and upload to the NodeMCU. What I wanted to do was create a device that would be recognized by Alexa that I could program to do what I wanted, ie. And a home with a network was just begging to have a home automation network installed. That said, I have had occasional issues with Ewelink switches which may be related to my network. If someone is using the other link in the comments well it needs 60ma to drive the wire coil so it might not work from the ESP which I think drives 40ma max.I love reading example articles like this even though pre-made parts like ewelink or a series of timer relays could do it too plugged in to any old wifi outlet.
