| Your home, most probably, has some kind of heating system for those months of the year when the outside temperature is too low to be comfortable. At least, in most of the world, every home has some kind of heating system. Of course, then, why don't we make it smart? | Your home, most probably, has some kind of heating system for those months of the year when the outside temperature is too low to be comfortable.

| The basic logic is simple: whenever at least ONE thermo-valve is open (heating), the generators should be operative. Only when ALL the thermo-valves are closed (idle), then the generators can be turned off (actually the pellet is not turned on or off, but switched between minimum to modulation...). | The basic logic is simple: whenever at least ONE thermo-valve is open (heating), the generators should be operative.

| Maybe i could remove the OrangePi Zero altogether using some ZigBee relays, or maybe coupling ZigBee switches with the relays i have today. This would require to rewrite in Home Assistant the logic between switching the generators and the various protection logic. | Maybe i could remove the OrangePi Zero altogether using some ZigBee relays, or maybe coupling ZigBee switches with the relays i have today.
