indeed, when thinking about your suggestion it makes more sense to make a slave-channel. as i understand bticino system this kind of slaves are only used in big rooms with more than one temp-sensor to be able to calculate an average-temperature for the whole room. don´t know how this can be managed, maybe someone has more than one slave, will this be also possible?
perhaps ist already too long that i use the name
bus_thermostat so i wouldnt mind. but of course, a thermostat is a device with some kind of control. i know bticino has other sensors what allow some kind of small control (i think it was plu/minus three degrees that where possible to regulate direct on the sensor) - for this devices the name would fit. other idea could be to call it just
bus_temperature_sensor - no matter if it has a possibillity to regulate, main mission of the device is to deliver the actual temperature. the term
bus_thermo_zone sounds for me more like an area. for example my living room is a zone that has two temperature_sensors and four heating_actors.
