I wanted to start a general thread on this topic to discuss anything about it in regards to home automation.
So I have an older revision RCS TXB16 which is a thermostat that speaks 2-way X10 for anyone not familiar with it. It is located downstairs, in an area where 4 different areas downstairs are connected, which I think makes the temp sensor on it not so accurate. Anyway, the house is also a two floor house, and in the hot seasons, it is always 100 degrees hotter upstairs than downstairs (exaggerated).
Some solutions cross my mind about how to remedy this:
[*]The TXB16 can support a remote (RS485?) thermostat which I could place upstairs. Then the main thermostat would average out the two temperatures. With this setup though, the upstairs would be a little cooler, but the downstairs would probably be a freezer.
[*]The other solution I can think of is to add two relay controlled vent dampers, one to shut off downstairs, and one to shutoff upstairs? Although I am renting, and this doesn't sound reversible, and would be a monster of a project picturing myself in the attic and what not (and there are no outlets for the relays in the attic).
So I know RCS makes remote thermostats for their main ones, and I also know RCS makes a zone controller system to work with electronic dampers. I am considering switching to Venstar for Insteon support, but am curious if Venstar has hardware to deal with my scenario above?
Does anyone have any other solutions for evening out the temperatures between upstairs and downstairs?
