Review: Great accompaniment to Ecobee system - These are easy to setup and pair quickly with your Ecobee system. No issues to date and have had them installed for over a year. Customer service with Ecobee has been top notch as well with trouble shooting other Ecobee products we have and had questions about.
Review: Perfect if you're looking for simple - 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.

## Features

- Real-time notifications whenever a door or window is opened or closed through the ecobee app. No Smart Security Subscription required to use this feature.
- When paired with the ecobee Smart Thermostat Premium, it can play a chime when your door or window is opened, for greater peace of mind. No Smart Security Subscription required to use this feature.
- Place SmartSensors near your valuables like drawers, safes, and medicines cabinets, and receive instant notifications if they are opened.
- Installation is quick and easy. Simply, attach a SmartSensor to a door, window, entryway, or other areas that contain valuable items drawers, safes, and medicine cabinets.
- SmartSensors gives you peace of mind that’s powered by an easily replaceable battery designed to last up to 3 years.
- With an ecobee Smart Security subscription you’ll unlock real-time push notifications when the system is armed. It can detect motion from a range of up to a 120° arc 16 feet away, notifying you when doors or windows are opened unexpectedly, or when unexpected motion is detected in your home.
- Save money and reduce energy waste, automatically. If an entryway is left open for 5 minutes, your HVAC system will turn off and notify you, helping reduce your energy bill and help the environment. Requires ecobee Smart Security Subscription and ecobee Smart Thermostat

## Questions & Answers

**Q: Does the door/Window sensor tracking needs subscription for the app ?**
A: This probably needs an updated answer since it's 2023. Through the Ecobee app, you can see the open / closed status of the sensor(s). However, if you have Apple HomeKit, you can configure it to notify you about it changing state (open / close) separate from Ecobee entirely.

**Q: If left open will these shut off the thermostat?**
A: No! The lock will engage after 30 seconds of closing or immediately after door has been open for 30 seconds...kr you can just eave door open! It does not affect the thermostat.

**Q: Is this Home Kit compatible?**
A: I don't use home kit, bu the thermostat is  homekit compatible and you can only use the door/window sensors with the thermostat... so I would say yes.

**Q: Where can I get a single pack?  I live in a top-floor condo and have one point of ingress.**
A: 🤷🏽‍♀️  I think they come as two pck only

### ⭐⭐⭐⭐⭐ Good product
*by K***N on December 2, 2025*

They are good quality. They are kind of big for a sensor. They function well, I am not sure if it is my app or the sensors sometimes they give a delayed notification. I am pretty sure it is the app because if you go to the app after closing the door it is showing closed then a few minutes later I will get the notification.
