Just got these Honeywell Smart Room Sensors for my T9 thermostat, and wow—what a difference they make! Super easy to set up (took me less than 10 minutes for two sensors). The motion detection is a nice touch—now my thermostat knows which room I’m actually in instead of just guessing.

The only hiccup? The included double-sided tape isn’t the most reliable. One of my sensors took a tumble off the wall (RIP, tile floor). I’d recommend using a screw or stronger adhesive if you’re mounting it somewhere high-traffic.

Battery life seems solid so far (they claim a year), but I’ll update if that changes. For $40, I expected a sturdier mounting solution, but the functionality is spot-on. Love being able to prioritize my home office temp while working!

Pro tip: If your sensor doesn’t pair immediately, don’t waste time troubleshooting—exchange it. These either work flawlessly out of the box or not at all.
