Implement ShellyPro3Em
Does the Shelly Pro 3EM only support Modbus/TCP or is it additional? Otherwise I would prefer staying with the default Shelly protocol.
Done ! As you suggested if all Shellys are merged I would continue to write an Abstract Shelly Class for all of them :)
@sfeilmeier maybe we can now merge this - what do you think ?
Added JSON Example in Comment - thank you for implementing this all and also fixing the Samsung ESS legacy Impl - will test at the evening !
