I would like to have ‘text area’ with buttons to change value up/down. Every change should be send to shell program after change too.
I can use DummyHeatingThermostat for that but how can I read value to DummyHeatingThermostat from program ?
I don’t know if DummyHeatingThermostat is best option to use in that case.
Basically I need a text area which value is sent to shell and also that value must be possible to update from shell program.
