IKEA Matter Contact Sensor
This $8 contact sensor is big because it’s built around a AAA battery, but it does the job: open or closed. I see it as an automation sensor more than a full security-system replacement, especially if you’re already using your security brand’s sensors on exterior doors and windows. If you don’t mind the size, it’s an easy win for filling in gaps.
Pros
- +Very affordable for a Matter over Thread contact sensor
- +Reliable basic open/closed reporting in my testing
- +AAA battery is easy to source
Cons
- -Physically large compared to many premium sensors
- -Battery access requires a pry tool
