get trigger from IFTTT - using ESP8266

Question

I'm using a Wemos mini, to switch on the light.

I'm trying to figure out how to combine IFTTT and Sunset and Sunrise from Weather underground to trigger the lights ON.

All examples I find, is how ESP triggers the IFTTT (using IFTTTMaker) but not the other way around, meaning ESP get triggered from IFTTT service.

Answer 1

If you want to send a "then that" trigger to your esp8266, you can use a webhook.

However, you need to do some preparations on your home network:

• You need to have a webserver running on your esp8266.
• You need to enable port forwarding on your router for one port to be forwarded to your esp8266.
• You need to know your public facing IP-address or you need to use a DynDNS service.
• You need to be aware about the security implications of opening a public facing port and forwarding this to your esp8266.

Here is what you then need to enter into the ifttt webhook action fields:

• URL: enter your public facing IP-address (including port that is forwarded to the esp8266) or your dynDNS address.
• Method/Content Type/Body: feel free to choose.

An example for a simple http call:

http://yourexternalip:yourport/msg?switch=0

Here is what you need to implement on your esp8266:

On the esp8266 you need to have the webserver check for a http request as configured in your webhook and react according to your wishes.
