433 Mhz RF Garage Door Project

[Federicobj]

Hi @kakopappa, I am working on a simple project and I need to see if you can help me. I have a garage door that opens with a 433mhz rf signal and what I want to do is using a nodemcu esp8266 + a 433mhz rf emitter that when giving an alexa "command" the rf signal is sent to the gate and I don't know how to implement it in the arduino sketch, any help will be very grateful, Federico

Not sure how good you are with Arduino programming. If I was you I would split this into 3 tasks

1. Wire the ESP module + RF and send a command. confirm that you can open / close the garage door using ESP module

2. Alexa - Esp link. Create a lock device in Sinric. Watch commands appear in the Serial terminal as you ask Alexa to lock / unlock the door (check the steps on home page). This is simple.

Use this Arduino sketch https://github.com/kakopappa/sinric/blob/master/arduino_examples/switch_example.ino

3. Merge the sketches

Good luck

@kakopappa, my arduino programing is not very good :( , I generay download samples and modify it, I never program any sketch from the scratch 1- I just clone the RF signal of my garage with an rf receiver, and then I send it with an emitter with two simple sketchs, thats works OK 2- I also made a sinric commando to turn on or off a light, that works great also :) 3- what I dont know how to do is to join this two things :):):), I think someting like this will work, but i think that someting is wrong on the sketch couse I do not see were to put the rf code, protocol, etc. https://www.instructables.com/id/Amazon-Echo-Switches-433mHz-Remote-Outlets-With-ES/

By the way, thanks for the super fast responce, and if you have any advice on how to do it or what is wrong on this sketh it will be very appreciated

Upload the sketch here without the API key. Me or someone else will help you when have time

Thaks you very much for your advice :):):) i get it to work !!!...My only doubt is which device in the list of sinric "device type" has only a "power toggle" button and not on/off state buton? besides that the sketch works great for open and close my garage my edited parts of your switch sketch are in BOLD, here you have the sketh if someone needs it

here is the sketch: / Version 0.4 - April 26 2019 / #include
