We spoke about the necessity to monitor the battery level (regardless of which technology we'll choose) of the temperature sensor.
But what if the thermostat were to loose its connection (because of a battery issue or whatever shit can happen) with the sensor for a longish period of time?
I believe we should include a sensor on the Raspberry Pi also to be used in simple setups (without the need for an external temp sensor) as well as a backup solution in the case of a connection loss. That means our heating algorithm should monitor the deltaT between the internal and external sensor (under normal working conditions) to be able to setup a 'degraded mode' heating policy congruent with the prime policy.
