Smart Home door/window contact, alarm system, break-in protection, compatible with Apple HomeKit

I only bought this for use with HomeKit and mainly automations. I prefer having base stations with my accessories as it is more reliable and I don’t like having devices connected via WiFi as I always find they disconnect to often.I have the contact sensors set up to send me a notification on my iPhone through HomeKit when no body is home and I also have it to play a burglar sound through my HomePods and also turn on various lights. The Bosch app it’s self is not the best you have to update everything individually and there’s no option to check for updates for al your devices at once. I am notified the second the doors are opened through HomeKit so it’s an absolute perfect set up and can be found at £25 sometimes which is the only time I buy them. There cheaper compared to a lot of reliable sensors compatible with apple HomeKit. On one of them I did have the adhesive come off it a few times but I bought some good double sided tape instead and it works like a charm.

Magnets are strong hence the gap between magnet and sensor can be larger than otherwise. Wifi reception is strong. The furthest away from wifi access point or bosch controller is more than 30 metres

Good product!It satisfied the basic needs

I cancelled them

One completely dead and the other fine. I purchased 4 thermostatic radiator valves and one of those was dead. Its ridiculous to recycle dead products to new customers

Combine it with the radiator thermostat and the home controller from the same company and it saves so much hassle. I don't have to ever remember to turn the radiator down when I open a window or turn it back up when I close the window. The room this is in is way nicer now. But be aware you need the home controller from bosch for this to work and that is not cheap just for one window. Think it through.
