I began with a frustrating experience with this thermostat. Wi-Fi connection was challenging and I was ready to give up until I figured out two things. One, since I didn't have a wire that provides power (older home) I found that using lithium AA batteries provides much, much better connectivity than regular AA batteries. Secondly I set up port forwarding as recommended for ports 8092 (UDP), and 80 (TCP). You'll have to log into your router to do this. Update: Nope, still randomly disconnects.

Unreliable. Unreliable connection to WiFi router 20 get away. Unreliable thermostat setting that change back after showing they've been set. Unreliable when AC shuts off randomly even though the ambient temp is several degrees above the set temp. Sometimes the darned thing turns on the AC without indicating that it's on! Really? What is happening here??? Terrible UI, scheduling is a so unnecessarily complex. Extra star since it's cheap and it works. But it could be so much better.

The app is working great so far. Quick and responsive, mostly easy to set up, detailed step by step installation instructions. I can set 6+ steps on my schedule to really fine tune things to be both comfortable and save money. I just wish the schedule let me select specific months it was used for, or at the very least which seasons to use which schedule for.
