ecobee 2pk Smart Sensor: Wireless Thermostat Accessory, UL Listed, Energy Star Certified, White, Includes Lithium Battery

So I got a two pack of ecobee sensors yesterday, it is a good idea but don't work the best as it averages out the temperatures and prioritizes the room you are in. So as I was downstairs it was warmer and the heat did not kick in making the temperatures upstairs drop slightly but more in my room as no heat was running. I usually keep my heat at 21.5 but the temperature in my room was 20, so when occupied the furnace had to run long and hard to get it up to 21.5. As I prioritize that room it keep that room at 21.5 while the rest of the house was hot. But as it averages out on the main thermostat it will read a wrong, 21 as you can see. I had my other thermostat above and it was 24 degrees.. while in my room was 22 because it overshot. Don't recommend them. The ecobee thermostat itself is great with a proper set schedule, do not use these sensors.

Product will not mount on the wall using the supplied wall mount. This failure turns a great idea into a waste of money

There is a firmware issue causing these not to pair with some older thermostat models. Ecobee has known of this issue for at least 10 months and is still only "colleting data". Meaning they are not actively prioritizing or developing a solution. If your thermostat is running an older version of firmware, do not buy. You will likely spend a ton of time troubleshooting only to be told it's a firmware issue. An honest company would note this on the product page to prevent customers the headache.

Way ways to expensive and not worth buying. The technology is old and should be using mmave at this point!!!!!

I've bought two thermostats; they work well. My parents like that

I switched to Ecobee from another popular smart thermostat brand because there was a lot of things that really bugged me about that thermostat. The Ecobee 3 Lite blew me away. The advanced features it gives you for those of us that understand what these extra settings are for, are just amazing. I was surprised at how well engineered the Ecobee thermostat is, the thought that went into the design, settings and functions. It literally does everything I could want and things I didn't even know I wanted. I know calm down right, it's just a WiFi Thermostat. NOPE. It's how ALL WiFi thermostats should be made and how they should function. It gives you plenty of abilities if you want them, but without forcing anything onto you or making things confusing. You get to decide what type of setup and how things will work for you. Eg: Just a "Hold this temperature" type setup, or a program to run at desired times, or when you are away, asleep, or awake etc. I just wish that I had bought this Thermostat sooner. I was missing out for so long and was frustrated with my other thermostat needlessly. Even the little sensors you can put into other rooms to make your home more comfortable. Just WOW! They thought of it all. My house is so much more comfortable now and my Ecobee thermostat is taking care of it all flawlessly. Bravo to the Ecobee team for engineering an amazing thermostat. You folks nailed it! Thank you for making such a wonderful device with all the advanced features you could ever want. You have made me a customer for life and I will be converting my friends and family as well!

Ecobee's SmartSensor is simply perfect! It is actually one of the secret ingredients to making your home feel just right. It’s designed to pick up both temperature and motion, so your thermostat knows not just how warm or cool a room is, but whether someone’s actually there. You can place it in rooms where you spend the most time—like your bedroom or home office—and it’ll help your thermostat balance comfort in those areas, rather than just where the thermostat is installed. It’s like giving your thermostat a set of eyes and ears around your home so it can keep you cozy and help save energy without you lifting a finger. Let me know if you’d like help getting it set up—I’m happy to walk you through it!

It literally was a dud for me. I followed all the onboarding and troubleshooting steps and it never registered on my Ecobee. For reference, I’m the CTO of my company so it’s not for lack of understanding how to set these things up. It just simply was a dud. Still waiting for a refund but we’ll see.

I bought these smart sensors thinking they would help determine hot and cold spots throughout my house and they never work. They say a room is occupied when no one is even in there. It just tells you what the room temp is. I had this mounted on my wall in the living room with my alarm system set. At 1:30 am it detected motion when nothing was in my room at 1:30 am and 10 min later the cops are banging on my door because of these sensor that went off saying my living room was occupied at 1:30 while I was sleeping. So then I had to explain to the officer what the sensors even were and that everything was fine. Waste of money don’t buy it. I can buy a cheaper device telling me what my room temp is…

I’ve got five of these through the house, now two years old. One has completely stopped working and another drops in and out. Replaced the batteries to no avail l.

These satellite sensors have completely changed the climate dynamics of our home. Let me explain. We live in a 100+ yo brownstone with small rooms and several floors. Up until we bought our Ecobee thermostat & sensors 5 months ago, we had no real way to calibrating room temps. Sometimes I would fiddle with the register grates, but then rooms that had been cold were now hot and vice versa. Impossible to find middle ground. Once we installed the Ecobee T stat & sensors, it has all been calibrated for us. If I wanted a previous cold room to warm, I’d put a sensor in there. If the room with the thermostat was too hot, I can now adjust the temperature range. Really glad these guys helped me find a solution and it also seems to be saving me some money in the meantime.

Definitely would not recommend these room sensors. They do not work and are a waste of money. It adjusts the temperature 5-10* colder in my 3 year olds room so during the night it drops into the 50’s. You would think the room sensor would not let that happen.

Works perfectly fine for temperature monitoring, but for the price should also measure humidity. there are parts of the world where humidity control is a concern, and being able to monitor it in different parts of the house would be extremely useful, as the thermostat is able to turn on the ac to lower the humidity.

I am a renter and have seen my electric bill jump so much in the last 2 yrs. I saw on my bill that they had a program that they would come out and access ways you can save money free of charge. My landlord was 100% behind this! Well they came and installed an ecobee thermostat! The one we had here was very old ! Now I can program what temp I want during the day for ac/heat as well as my night temps! I saw a change in my savings the first month ! I continue to see savings 6 months later. The reason is because you are not having to keep changing your temps. This is so easy ! Check with your electric company they have contacts with ecobee then you can get the extra room sensors ! Been worth it ! Save the money you save for something fun for yourself!

I have one for each room and though it is nice to get an idea of which room tends to run hot to be honest unless your house is on an automatic zone setting then your AC will run and run and run and one part of your house will be freezing while the other part is ok.. I ended up removing all of them and now the main thermostat controls everything and so far so good.

Not up to expectations. Had to replace from 2 property. It gets minds of it own amd start AC in middle.of winter...

After latest software upgrade the thermostat does not work properly. Temperature drops significantly and heater just won’t turn on. I do not recommend this product.

I’ve always been using the solution. I believe the main flaw is on the temp sensors not being smart enough. I say this based on all tests and tweaks I’ve made with it over the course of using it. Temperature detection is spot ON but occupancy detection does not. The main flaw is the refresh rate for occupancy detection. It can’t be changed and takes more than 20 minutes to refresh which does not help when doing follow mode. If they can add the option to adjust the refresh rate for occupancy feature then I can recommend it and support it.

This unit has been a pain and aggravation since I purchased my home and it’s only been a year

The thermostat always reads warmer than what it really is in the house, even with the extra sensor which has now died and is useless so it's either really cold in the house during winter and I have to turn the threshold up or it's really warm during summer and the a/c will constantly running. The extra sensors are never in stock and you can't get them anywhere else. Kinda useless to have an accessory for a main product that is never available.
