The Honeywell T-9 thermostat was extremely easy to connect to my home Wi-Fi and get up and running. I love how easy it is to adjust the thermostat from your device. We went on vacation for a week and it has a great “vacation setting” that can be used to adjust the heat to a lower setting for all the days we were gone. It’s a money saver for sure. My only suggestion would be to have it professionally installed on the wall. That part was way beyond us.
I would recommend this to a friend!

Make sure you check the fine print!! There's a very small note on the door of the wall connector that has some specific connections that are required for a heat pump system. This drove us nuts as we did not notice that until two days later. Once that was connected the unit is a really great themostat!!

Had a semi smart, 2 wire thermostat that was dieing. After a lot of review, mostly regarding shape and programmability, we chose the T9. Luckily my house was wired for either 2 or3 wire install (T9 requires 3). Install was easy, and after reading installation manual setup was pretty clear and easy. Honeywell also included a remote sensor to monitor an additional space (we have a large house). We installed the extra sensor in the basement. It's always a little cooler down there and the system used it's readings when motion is seconded in basement. The main unit also uses motion to trigger the temp readout to ON condition. Overall seems this T9 fit our needs perfectly..

This works just as it states and is amazing. The app and thermostats link well and work well with other trusted household apps.

My purpose in buying the T9 thermostat was to better regulate the temperature in our master bedroom during sleeping hours. Using the remote sensor included in the package, that goal has been accomplished. At nighttime I set the system up so that it looks at that sensor only. The system is very flexible in that you can give "priority" to any combination of the devices you connect to the thermostat (up to 20). If you select multiple devices, it will work toward achieving your desired temperature over the average of the selected sensors.
One reason why I purchased the Honeywell T9 as opposed to competitive units (e.g. Nest) is that my understanding is that some of the others will not allow you to set a temperature and hold it. I would rather have personal control over the temperature in my house as opposed to leaving it to a "smart" algorithm.
The installation instructions are very detailed, but I had a couple of problems. First of all, this thermostat requires a "C" wire. If you don't have this wire, you use the included adapter which must be installed at the furnace end. That can be problematic, depending on your particular furnace configuration. I didn't have the a "C" wire connected to the old thermostat, so I thought I needed the adapter and started that install. The instructions give the expectation that there is a nice, neat terminal strip in the furnace to connect to. Instead, my HVAC unit was like a "bowl of spaghetti" wires connected with wire nuts. I finally realized that the HVAC installers DID connect the "C" wire on the furnace end but that it was tucked inside the wall on the thermostat end. With that realization the installation became relatively trivial. The manufacturer covered this in the instructions but it can be easily overlooked. If you have to dig into your furnace the probability of a DIY error increases dramatically. A video would have been helpful.
My other problem had to do with the setup on the thermostat end after completing the physical install. Certain steps can be postponed until later so they say, but if you do, good luck! For instance, my experience was that I couldn't connect my smart phone to the thermostat because I had initially skipped that step. In the end I did a factory reset, didn't skip any steps and the smart phone connection went as planned.
Another issue had to do with the geofence option. Once your phone is connected you are given the option of setting up geofence. I did that but later decided I didn't want that option, but it wouldn't let me remove it! You can temporarily disable it, but you can't totally get rid of it. Note that if you use geofence you cannot setup a daily / weekly schedule. I had to remove the thermostat from the phone app and, once again, do a factory reset to get rid of geofence. After that, no problem.
I am very optimistic that this product will meet my needs very well and would recommend it to others with the cautions mentioned above. It looks good and performs well.
