I have 4 thermostats located in four different zones and a separate AC thermostat.
I want to get some programmable thermostats for each location. I could buy 4 individual programmable thermostats but they're like $100+ each.
Is there some product where one thermostat act as the master with all settings, schedules, etc. and the other thermostats only act as receivers (i.e. they only receive a command to set the temp).
Multizone thermostat (where one single thermostat can control multiple zones) doesn't work since there's no master location (all thermostats are in separate locations).
