Review: Great HomeKit support - 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.
Review: Do what they are designed to do. - 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
