/*
  ClientSendCommand.ino - Example for TasmotaClient to respond to ClientSend ON and
                         ClientSend OFF commands via console or telemetry.
                         In this example the ON and OFF is case sensitive so needs
                         to be sent in capital letters from the Tasmota device.
                         Upon receiving ON/OFF the client will turn the LED on/off
                         respectively.
                         
                         A second function callback is also attached which will
                         respond with a JSON message on Tasmota Teleperiod when
                         requested from the Tasmota device.
