Why I stopped hacking the Amazon Dash button and learned to solder

Is there something like esp8266 for IR diode and receiver? I am wondering if usage of IR would be better for home IoT projects. WiFi frequencies are quite crowded nowadays and I would think that it is not the case with IR. Also it probably would use less energy.

If LiFi can work, surely IR should be good enough for simple signaling? Maybe there could be also a repeater in every room connected to mains for power and WiFi to signal each other?

It maybe interesting to have IR signals somehow encrypted.

There are endless modules to attach. There is both an IR one and a 400MHz radio tx/Rx one. IR is like 50 cents, radio is like $1.50 I think on AliExpress. The radio is probably better than IR since it works pretty damn far and without LoS.

ESPs have tons of IO. You could add IR to it if you want.
