ecobee Smart Sensor for Doors & Windows 2 Pack - Wifi Contact Sensor for Home Security, Energy Savings - Compatible with Smart Thermostats - Temperature sensor, white

When I changed out my 23 year old furnace/ac it was also long overdue to change out the thermostat.I have been very pleased with the Ecobee thermostat and remote sensors that can be paired with it and placed around the house. It came with one sensor and I bought and additional pair of the sensors to spread around upstairs and be able to weight the averaging for AC purposes more heavily based on the up stairs rooms.I like the ability to check the temp in the various rooms of the house thanks to the sensors and set the thermostat up or down as needed, even when I am out of the house.

I bought the Ecobee thermostat, room sensors, and these door sensors when they were on sale. So far they work GREAT!!! They notify us through the app every time someone opens or closes those doors (which can actually be quite annoying). We also set up the thermostat to turn off the AC when one of these two doors has been left open for more than 5 minutes. It always notifies us that it has been open for more than 5 minutes, and that it is shutting the AC off.Con: We wish you could set certain times of the day when it wouldn’t notify our phones. And have it be different for each person who has the app.

I only wanted this product for the thermostat. I already have a security system.Unfortunately, you have to pay $5/mo. to use this with the thermostat. It will tell me there is a door open, but won't pause the HVAC. It doesn't track that this is a 'security system' that is worth paying a monthly fee. Installing these also triggered a trial of the security plan, which took up the top half of the screen on the app and moved my thermostat controls to the bottom half of the app.Overall, this product was a bad experience. I wish I could return it, because I could have my actual security system (Eufy is great!) tell me if a window is open (and with cheaper sensors and no monthly fee). All I wanted was a more efficient HVAC, and Ecobee failed miserably, which is sad because I love the thermostat. Hopefully they don't decide to start charging a monthly fee for that.

I've long avoided door and window sensors because most of them have an ear-splitting alarm built in, and while I understand the reason for that, I'd rather my dog not be traumatized every time I accidentally set it off. So these ecobee contact sensors are actually pretty perfect for me -- without the monitoring subscription. They're simple to set up, I don't need to change the batteries often, and they do nothing more than send a notification to my phone when the door/window is opened or closed. That's it, and that's the main thing I need from them.For everyone else... Well, you're probably going to find them useless without a subscription. If you pay for their monitoring subscription, the sensors can alert you to motion, turn off your HVAC if a door or window is left open, tell you when someone's home, and remind you to arm the system when you're leaving. Without the subscription, you get none of that, so keep that in mind when considering whether to purchase. Granted, the subscription's pretty cheap, but it is extra money you'll be spending each month.

The sensors themselves are very well built and are very easy to setup. They also seemed a bit overpriced for what you get perhaps 20 to 25 dollars per sensor would be more appropriate than 40 dollars per sensor. Also it seems to require a Ecobee Haven subscription to make any use of them and for me not having an Ecobee camera it just doesn't make sense. I am currently using Ring Cameras and already have a subscription for that so I don't really need another subscription just to receive notifications from these sensors. Also they sensors don't seem to support IFTTT.What would make these sensors a whole lot useful is if Ecobee enabled their use without a Haven subscription or lowered the cost of the subscription for people not using the cameras. Also it would be really nice if they enabled IFTTT support with them, in my opinion that would make them a whole lot more useful.

Love the idea and they work fine. But the sticky came off when I needed to move one side. Bummer

Product works as designed and helps save energy bill costs when the door is left open bringing in groceries and works with the Ecobee Premium thermostat to turn off units. It has a toggle feature that notifies me about the door opening/closing and that is nice to have when you have kids. Excellent addition to smart home.

I just bought two more of these to add to my home security. They are easy to install -- but MAKE SURE you get the placement right before adhering them to the wall or door jamb. I had to buy super glue to reposition one of them, because I made a mistake. I've been using the Ecobee thermostat for years, and I'm happy with it, so I expanded my Ecobee collection with these door and window sensors.
