Why would I need a C-Wire adapter?

Pull out your current thermostat before ordering! Mine only had 4 wires hooked up (battery powered with heat and AC) but there were 4 other unused wires in the wall. In my case the unused black wire was the C-wire (common wire) which was not hooked up to my battery powered thermostat. So I didn’t need the adapter even though some of these “answers” said I would if I only had a 4-wire system.

Can I use multiple thermostats in same house?

YES, I just installed and set up 2 of these for my own house using only the Alexa App on my phone. I am a Licensed HVAC contractor in WMD Area but it is pretty straight forward installation for anyone. Take a picture of where the wires connected on your old thermostat, connect them to same ones on this one. TWO THINGS; 1- Just pay attention to the warning label on the wiring cover for heat pumps about W terminal. 2- FOR HEAT PUMPS ONLY, O/B is pre-set for O(Energized in cooling) some heat pumps, Ruud, Rheem, Mr. Cool Ducted Mini Split, Carrier Ducted Mini Split, etc. Units use B(energize in heating) make sure to check your heat pump.. To set-up for multiple heating cooling systems, you just have to pick a name for each one from pre selected list or create a custom one based on your heating/cooling system. You can then adjust the time and temperature schedule for each day of the week based on your schedule. It works with Steam or Hot water Boiler and COMBI Boilers, but you need at least 3 thermostat wires. RED to R terminal for HOT on 24Volt side of the control transformer inside the heating system. WHITE to W terminal for HEAT. 3rd Wire to C terminal or COMMON side of the 24 Volt Transformer, you may need a professional to do this if you don't have an existing one. As always; TURN POWER OFF TO ANY APPLIANCE RUNS BY ELECTRICITY. I hope this was helpful.

Will you be able to use remote room sensors?

I would definitely consider this Thermostat, but it doesn't work with remote sensors. We have a single level ranch and I have 3 sensors hooked up to my Ecobee thermostat. For instance, at night the wife and myself like it cooler than most, we set the thermostat for 67 degrees, but with the sensors, I can set all of the other sensors (including the Ecobee) to off except the one in the master bedroom. That way the master bedroom will stay at 67 degrees. We also have one in my wife's home office, so during the day when she's home alone, only her office will be at the set temperature, not the entire house.

Can I set the thermostat to change to different temperatures at different times of day on different days of the week?

Something to consider if you want more than 3 temperature options (Home, Away, Sleep) is to set up routines. Set the routine(s) to a schedule (Days of the week and times of day) and tell it to set a specific temperature on the Thermostat. You could run all your thermostat schedules via routines or (I assume) in addition to the basic (3 tempt) Thermostat schedule. It's more work than I'd prefer but it is an option.

If no one interacts with Alexa for a while at night, she might have a hunch everyone is asleep. When someone interacts with Alexa or uses smart devices, she can tell that someone is home. Alexa learns from your daily interactions and improves over time. You can also help Alexa know when you go to bed or leave home by saying, “Alexa, goodnight.” or “Alexa, I’m leaving.”
