No problems - set from bed

To the folks who recently complain about multiple furnace screen - I don’t know what you did, but open up settings and it’s simple to correct. User error?
We have really enjoyed our new thermostat and this app, installed about 4 years ago. Updates have been good. We've had no connectivity problems, and setting schedules and modifying is straigh simple. It can be set to adjust to outside temps too instead of just time of day. (You can set it to reach the temps you like AT the time you like knowing Sensi will actually turn furnace on sooner and full speed if its really cold out, and closer to the schedule time if it’s only cool out.) I LOVE being able to control our furnace from bed - turning it up early if I wake early, or down if we want to sleep in later than usual. We have even used it from the airport to be sure we returned to a toasty house. I thought our old programable thermostat was fine, but I would never go back now as this system allows much more flexibility for saving energy while you’re sleeping or at work, while still keeping you comfortable. A solid app. We have not tried the beta location app that adjusts temp down 3 degrees if your phone leaves, and turns on as you near home... we keep a pretty predictable schedule and just overuse that if it’s an odd day.

Honest review from a rational person.

I’ll start by saying I got my thermostat free from my local municipality. If the thermostat you’re replacing is an old ‘set it and forget it’ wall dial this will be a huge upgrade. I’m not going to get in-depth with its features other than to say you can control this thermostat with your smartphone anywhere on the planet as long as your thermostat has connectivity to your home wi-if. Now with that said, in regards to connectivity issues voiced in other reviews; yes, it will occasionally lose connection to your home wi-fi. I’m not a network expert. I can’t explain why. I can understand how this immediately throws people into a tizzy. It’s been my experience however that if you just let it be it reconnects itself automatically, usually in less than a couple of minutes. Your experience may vary, again I’m not a network expert. It doesn’t happen often enough though for me to warrant immediately panning it (‘one star!!! This things garbage’). I’d say 95% of the time it opens immediately on my phone. It’s a small gripe for me and the specificity you have in setting heating and cooling schedules outweigh it. Now for the big gripe. After you sign up for this app the your junk mailbox will increase by 40+ messages a day. No joke. Nothing is ‘free’ I guess. Be warned.

Works as Advertised

The WiFi functionality was up and running in about 10 minutes. Very easy if the directions are followed. I love all of the advanced settings related to heat cycles, geofencing, and sensitivity of thermostat. Already I notice that my furnace isn’t running nearly as much this winter and my home is still at desired temps. The only issue I have was that when ordering my new thermostat, the Sensi was advertised as one of the few smart thermostats that “doesn’t need a c-wire” to replace older thermostats. This is a tad misleading. Although you don’t need a dedicated c-wire, your wire configuration has to be altered if you don’t have one. The installation walk-through on the app never addresses this. I installed per the app and furnace wouldn’t turn on. After an hour I luckily found a tutorial video on the app that showed how to use the “fan” wire as the c-wire. This worked, but you lose the ability to use the fan to circulate air. All in all, I love the thermostat and app, but wish the c-wire comparability would have been communicated better. Lots of people are replacing older thermostats that do not have more than 4 wires.
