HoneywellHome RCHTSENSOR-1PK, Smart Room Sensor Works with T9/T10 WiFi Smart Thermostats

It connected easily to my smart thermostat and makes the temperature control much smarter by turning this remote sensor into the primary control for the thermostat

Work well - have these in almost all rooms and sets priority and averages with T9 - when away you can see if any freezing temps in parts of house so lines don’t freeze etc I. Wibter

Muy bueno pues detecta la presencia humana y la temperatura en el área y se complementa perfectamente con el termostato inteligente T8 .

I like that Honeywell has made their sensors affordable, or more accurately, Amazon pricing on them is good at the sub-$30 level. The sensors I've ordered have been very easy to setup with my T10 thermostat and I like that I can keep an eye on how the temperature is distributed throughout my house, especially upstairs (thermostat is downstairs) and that you can use an average of whichever sensors you want to determine how the HVAC will operate.

Our thermostat unfortunately is placed where it gets morning Sun for part of the year, which has always made it think the home was warmer than reality on cold February mornings! So.. enter these remote sensors at C$24/ea. I placed one out of direct sunlight in the main living area, and used the T9 thermostat's touchscreen to set it up and to use it rather than the sensor built-into the thermostat itself. Problem solved, and the sensor is in a better area of the home as well.Got a second sensor for the master bedroom area, too. These are easy to install (special double sided foam mounting tape included in the package), and use a dedicated RF link to/from the thermostat rather than WiFi (the thermostat itself also does use WiFi).Recommended at C$24/each! I might get more of them..
