I have an old 2 story house with a steam boiler. I need to control heating with downstairs a sensor during the day and a upstairs sensor at night to manage comfort. I can do this with dual programmable thermostats wired in series but the WAF will be low. Is there a advanced thermostat that can switch between sensors, not average? Could I do this with a home automation set up? I also want to automate some lighting so it my be work the extra expense.
