The updated app includes weather info - that’s cool. Not sure why the charts had to switch from vertical to horizontal but at least they added the outside temp history to the chart. I don’t like the fact that my historical data doesn’t appear. I also think the person who picked the color scheme and the QA person should be fired. Not only is it ugly, the red font is unreadable. The dial to set the temp isn’t as intuitive as you would expect.

G2 thermostat

4 days in and Good so far. We have an older furnace that doesn’t have a control panel per- se, just wires. Thank goodness my husband is an electrician and figured out a way to wire it since we had a “C” wire on the thermostat but didn’t have a “C” at the furnace. Other than that one issue, it was set up very easily. I like having the app on my phone and can adjust temp with occasionally depending on weather, even if I’m not home. I do wish the app had a few more setting options for scheduling rather that just 2 a day; but again, I can adjust from my app if I remember. Haven’t tried setting up the app on more than one phone yet, but have heard that isn’t an option. If so, that’s disappointing.
All in all, decent for the price- FREE through our local electric company.

Thermostat consistently read 4 degrees too high

We were able to get all set up and going after some trial and error and video watching. Perhaps there is something wrong with our unit at it reads 4 degrees higher than actual temperature of the area near the thermostat. I would like info on how to fix this issue or a replacement.
