I have a somewhat unusual situation, I think. I have a finished basement apartment in my house that I want to rent as a vacation rental. Until I can go the whole nine yards and install either a separate HVAC system for the basement apartment or a damper zoning system, I want people staying in the basement to be able to adjust the temperature of the HVAC system, basically overriding the temperature set on the main level thermostat.

I also want to be able to monitor and adjust the temperature of the whole house remotely from my phone or computer via a wifi connection, because we will be away much of the time until we move to the house on a permanent basis.

I haven't found anything that seems to do what I want. I am finding several options for wifi thermostats with remote sensors (Ecobee and Nest, and probably others), but you can't change the temperature up and down with the remote sensor. I have also found a non-wifi thermostat system (Venstar T1800 with T1119RF Add-A-Thermostat) that does exactly what I want, but it doesn't have wifi remote control. Basically, I could install the T1800 where the current thermostat is, and install the T1119 in the basement. Whichever thermostat is adjusted last controls the entire system. But the Venstar thermostat doesn't have remote wifi capability.

Does anyone know of a wifi thermostat that has a second remote thermostat that can be adjusted up and down? Or another solution to my problem?

 

Get the wifi stat of your choice. I like the Honeywell pro 9000. install the stat in the basement and the sensor upstairs.
