Is now few a days that I'm running 3 Touchscreen Thermostats.
What is happening is really strange and I cannot even understand reading the log files because there is no trace.
Randomly some of them disconnect from the server and brake the connection.
First thing I try is to reset the Thermostat, or turn it off and on again, in order to reboot. But still does not connect at first time.
The debug of the thermostat when brakes the connection ends with a mystery sentence "CLOSED".
I also have other sensors like the external temperature that have no problem.
