Reed KumoSensor

The Reed kumosensor-door and window contact sensor

Amazing and 100% reliable. I used to use the regular sensor tags for my doors which wasn't the best at monitoring the door opening and closing. This reed kumosensor on the other hand is amazing, works every time and easy to install. I have it on every door in my house. The timer function is great to set what time you want to arm and disarm your sensors automatically!!

Exactly what I needed

I was looking to add some sensors for sliding doors. These fit the bill nicely. They are pricier than the other sensors, but I'm getting good temperature data from them which is a nice bonus.

Works Great!

I bought this in conjunction with the water temperate sensors from Adafruit to measure the water in my pool. Works great as long as you don’t let in fall in the water like I did the second day. Will buy more for my fish tank and pond as well.
