5.0 out of 5 stars A Great Choice.

We have a Honeywell on our second floor unit and an Ecobee on our first. Power surges took out two previous Ecobees and so we switched to the Honeywell system. In many ways it is superior.

1.0 out of 5 stars Four wires and C-Wire

2026-01-09    -Dale Shoudy

The T9 was unable to detect that my heater/cooling unit had cooling. The only modes it showed were HEAT and OFF and the fan continued to run along with the a/c even when OFF. I realized after I returned the unit that the installation instructions omitted a very important step. My wiring contained a C-wire (with R, W, Y) which had been repurposed from the G-wire. The installation instructions indicated that I subsequently did not need the C-wire adapter. This is false. The C-wire should be moved back to the G-wire and then the C-wire adapter used at the furnace. If you have only four wires in the wall and one is a C-wire, the C-wire adapter will need to be used. I can say that this only applies to a natural gas heating and cooling unit - don't know about other type of units.

This has been great in balancing the temps. It has a few modes but ultimately you’re able to prioritize rooms. There’s also a mode that will run the fan every so often for circulation. The room sensor has really helped balance our temp difference. Works with ring and Alexa, didn’t try apple

I had ordered this product for an install. However, the Install provided both thermostat in the process. So I had to return this item. It was quick and easy return and the company exceeded expectations. Highly Recommend both the product and the company!

2.0 out of 5 stars Need daily use reports

2026-02-12    -Happy camper

This is a good smart thermostat. But i wanted the daily use report or data and the residio app support/honeywell will not give you your own data that they are ccollecting. You get a monthly heat, cooling total hour use report for the month, so you know they are collecting the data. They say the user has total control, but in fact, not when it comes to accessing your own equipment for daily use reports. Only reason is that i want to view cooling use other than via a scheduled routine. Other smart tstats have that feature. All in all, its a good tstat, but im moving over to a nest to have better control over my own data and become a more efficient energy saver in phoenix az. Electric bills during summer average $500/month, 77/78 degrees. 2- 10 seer ac units with a small family!

Just as advertised, easy install instructions, very complete kit for the box we ordered, all is good and running. Love it, ordered another for the other unit in the house.
