I'm not sure if this the right place to ask, but I try anyway.

I'm looking for a remote controlled relay switch(230v/12v) that is controlled by a webpage/internet and I want this too be one unit whit sim or esim so it can communicate through tcp/ip protocoll or similar. I know there is ethernet relay, and gsm relay that you can call too. But I want to control it by data signal two way, and not by call or sms.

 

This is a very complex project, it does not include 1 relay, there are other modules and programming that you need.
