Easy to install and compatible with major smart home platforms, it empowers users to control home comfort remotely via the Resideo app. ## Description Smart Room Sensor Place Smart Room Sensors where you want to see each room's temperature and humidity. Use the multi-room display on the thermostat's touchscreen or in the app to easily focus on rooms either based on their occupancy or according to a specific schedule you choose. Review: Perfect addition to our new furnace - After our furnace died during the coldest week yet this winter, we had to finally bite the bullet and replace it. The new one is crazy efficient and works so much better than the old one, but that in itself raised a new problem where some rooms are now sweltering while others are lagging slightly behind. Enter this cute like smart sensor. We placed one in the room furthest from the thermostat and within the first day, noticed a big difference and figured we'd add one more for the opposite end of the first floor. We then set the thermostat to average these readings. You can also have it adjust for only when rooms are occupied, or manually override very easily through the interface, but for us the average feature is working best. You can add up to 20 sensors, which I feel would be crazy overkill for our 1800'ish sq/ft first floor, so we'll see how this do over the rest of the winter. Overall very pleased with easy installation in the thermostat interface and if you can attach a command strip, then mounting them in the desired room is a breeze. I'll revisit the review if anything strange comes up. Review: Good complementary sensors - These addons are great complementary equipment when you have a multizone house that you are trying to heat or cool. I have the T9 thermostat and these connected beautifully. They function well in the Honeywell (Residio) app and they are small and easy to conceal on walls in the areas you are trying to get additional temperatures on. When you go to program the schedule, you can tie in these sensors depending on time of day and room averages you want to account for. ## Features - Compatible with series 3 & Series 4 T9 Smart thermostats.

So say for example the upstairs is much hotter than downstairs. The valves upstairs will be shutoff.** A: This device itself does not control anything. This is just a sensor. This combined with a T9 or T10 thermostat work great for homes with improperly configured zones, or if there was remodeling done that change the heating dynamics of the rooms so to say ( like me removing the sliding glass door in the bedroom and opting for an energy efficient window ). Lets say room A has the t9 thermostat and room b is 1/2 the size of a and has not thermostat but is part of the same zone as A. Room b is bound to get much hotter than A ( assuming no other variables ) Buy one of these and stick in it B and you can now tell the thermostat to listen to this sensor in room b to make room b comforitable. **Q: Assuming I have a T9 installed, can the sensors be used to trigger events on other devices?** A: Yes it absolutely can! Don't forget that there is a motion sensor in there and with HomeKit, you can use these sensors to trigger any number of additional actions! **Q: is a C-wire or C-wire adapter needed?** A: This sensor wirelessly connects to your T9 and T10 thermostat. The thermostat its self will need a c-wire. -Joey ## Customer Reviews ### ⭐⭐⭐⭐⭐ Perfect addition to our new furnace *by M***L on December 19, 2025* After our furnace died during the coldest week yet this winter, we had to finally bite the bullet and replace it.

Great Solution! *by D***S on April 10, 2026* If you have a home with Honeywell T9 or T10 Thermostats, this is a great remote sensor for nearby rooms. In my case, I own a vacation home in Sun City. My home, a Voyage model has two bedrooms and three heating/cooling zones. The thermostat in question is in the common hall just outside the guest bedroom doors. When my family visits, they close the doors at night, making the thermostat unable to read the temperature in the two rooms. The sensors (I needed two) are very easy to set up and give them priority over the main thermostat. I just installed them this last week and they worked exactly as I hoped. After the family left, I returned priority to the main thermostat. Highly recommended! ## Frequently Bought Together - Honeywell Home RCHTSENSOR-1PK, Smart Room Sensor works with T9/T10 WIFI Smart Thermostats - Honeywell Home T9 WiFi Smart Thermostat with 1 Smart Room Sensor, Touchscreen Display - Honeywell Home T9 WIFI Smart Thermostat, Smart Room Sensor Ready, Touchscreen Display, Alexa and Google Assist --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/112160261-honeywell-home-rchtsensor-1pk-smart-room-sensor-works-with-t9](https://www.desertcart.us/products/112160261-honeywell-home-rchtsensor-1pk-smart-room-sensor-works-with-t9) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-04-26*
