Re: How to connect two esp8266 modules across the internet?
Posted: Thu Feb 22, 2018 4:08 amBut with dweet.io you either have to poll on a new dweet or deal with chunked HTTP responses.
Agreed that with dweet on ESP has to send and the other has to poll. However dweet gives flexibility, anonymity and is hassle free.
You could also do this with Thingspeak.......But then you would have to poll also.
If you just need to turn a led on and off you could also use IFTTT.
One ESP sends a request and the other sends back.
Make the recipe for both and you can communicate two ways.
