Esp should check at boot if the controller is connected.

Idea:

boot calls a function from solar tracer to test the connection
solar tracer (epever in this case) tries to fetch a single variable few times until
if it receives all good response -> communication is ok
if it receives them mixed -> communication is working, more or less
if it receives no good response are received -> communication is not working
