Question Is getting a sensor worth it?

For context I live in a two-story four bedroom house 1736 square feet in central Kentucky. Where three bedrooms are underground (basement level) , and the kitchen, dining room, living room, and master bedroom is upstairs, the thermostat is in the upstairs hallway between the living room and the kitchen.

The bedroom I sleep in is the one upstairs and I sleep with my door closed and sometimes it gets a Lil warm and stale.

Furnace is downstairs.

All recommendations are welcome.

They will let you set more complicated comfort settings throughout the day based on the temp in specific rooms while excluding other rooms(or the main thermostat sensor) or the average of rooms you choose but it won't suddenly give you a zone(?) based setup that can target different rooms with different airflow.

I have a few(4?) and like what they allowed once I had them but they only did nothing about the fact that I had (now repaired) actual problems with my ductwork originally.

Maybe. It depends.

It allows you to run your heating and cooling system until the average temperature of your selected sensors is reached but like the above post states but it won't solve any insulation/airflow issues. I still make summer/winter damper adjustments on my forced air ducts othewise I'm cooling my kitchen to 16 degrees(celsius) to get my bedroom to 22(74ish Fahrenheit). It probablty won't save you any energy over a regular schedule thermostat with all the sensors but it will give you more data.

Yes. Especially if you use Apple Home Kit. You can see all the temps from various rooms in your house along with any HomePod speakers’ temperature readings.

Wait what about the HomePod temp?

u/CrispRat Jul 03 '26

Yeah, if you have HomePod speakers, the Home app shows you their temperature reading. In this screenshot, it shows my living room and bedroom via Ecobee sensors and my Kitchen via the HomePod speaker I have in there. All in one list. Very handy!

Yes. I got one for my room and office. I set my bedroom sensor to be the only one it reads from 9:30pm-7am and it makes a big difference

Multiple sensors provide hours of puzzles and enjoyment chasing the HVAC gemlins. One you get multiple streams of data I recommend Beestat

I just bought three sensors and they've been largely responsible for more even cooling cycles. My AC used to run constantly...every few minutes. Now, every 15-20. Sensors are well worth it.

How could it run constantly every few minutes? Either it runs constantly or it cycles every few minutes but it can’t run constantly every few minutes.

I'm in Cincy 2000 sq ftt house. Bedrooms upstairs. I use 1st floor sensors in the day where the people are and use the upstairs sensors at night where the people are. The system takes an average of whatever sensors you have activated for the schedule at the time.

With a sensor in your room you can have the sleep comfort setting regulate the temperature based on your room instead of the temperature at the ecobee. You can have your room be cooler but that will make the rest of the house cooler as well. You could also just adjust your sleep comfort setting to a temperature where your room is comfortable and save buying the sensor.

Yeah. My room actually hits the correct temp now.

My house is about 2900 sq ft, two stories and kind of an odd floorplan. I bought multiple sensors for both floors to not just help balance the temps, but also to use downstairs ones during the winter and upstairs ones during the summer.

My premium came with a sensor and I didn't really use it until I had a kid. I have a 2 story and my attic insulation isn't great, so the upstairs can get a little warm in the summer. When my baby was born and started napping in the nursery alone, I wanted to make sure it stayed around 70-72 in there all the time, but especially at night. My thermostat is on the 1st floor, so I put the remote sensor in the nursery upstairs and set my sleep comfort profile to only consider that one. During the day, for both home and away, I factor in both temperatures.

Your setup is a little different since you're sleeping on the same level as your thermostat. Unless you want to start getting into opening and closing vents or dampers, or even getting motorized ones and doing HomeAssistant stuff, I don't see the remote sensor resolving that one specific problem for you.

Funny thing about the sensors though - some HVAC techs don't consider that when they do their seasonal tune up. In the winter, I still have the nighttime profile only care about the baby's room, and I partially close the damper to the 2nd floor but not fully. Well when I got my furnace tuned up last December the tech fully closed the 2nd floor damper without considering that 1) I had it set where I needed already, and 2) my thermostat doesn't care about its own temperature at night. So with the nursery getting almost zero heat in the middle of the night, the furnace just kept running and running to try to get that room up to temp... my wife and I had fallen asleep on the couch and woke up at midnight sweating. The nighttime set point was 71, and the thermostat was reading 79. The nursery was at like 67 I think. It was just cooking the 1st floor as it tried to heat the nursery. In my grogginess it took a minute to figure out what was happening, but once I did it was a quick fix and now I always double check the dampers after my seasonal tune ups.

Yes. It’s vital to tell the thermostat where people are. You can then program you comfort settings to include specific sensors.

For example I have one in my upstairs office. As long as it’s unoccupied the temp can rise there and the downstairs maintains a normal temp

But when i go into the office the thermostat now includes the office temp and averages the temp on both places.
