Just had 2 new composite doors installed and there was labels in the door jamb about these, I scanned the QR code and was able to enquire about the sensors. They are actually free and included with my doors (in the post to me now!)
From what I can see, they actually sense whether the door lock is locked or not and then you can install a App which can notify you if you leave the geofence area and doors or windows are unlocked :o
I have emailed them for more technical information, it would be great to be able to integrate these with HA. They seem to have been out for a few years here in the UK, but its the first I had heard of them. https://getkubu.com/manual/
Sorry for delayed reply but did you have any luck with these? We have Kubu-compatible doors and windows, and I emailed the company a while ago. They said they were planning to release some Matter-compatible sensors at some point but no sign of them yet…
Didn’t get much back from them, have discovered they operate at 868MHz, so have ordered a receiver to try and get it working with HA to receive the signal and send over MQQT.
I already have one that works on 433MHz to receive my oil tank sender, so hope the same code can be repurposed on this frequency.
Its a low priority project, so may be some time until I get back to it.
That would be great. I built an ESPSomfy-RTS 433MHz controller to control our blinds and it works really well with HA. It’s beyond my capability to reverse-engineer the Kubu radio signals though! Do let me know if you have any luck.
thanks for the info about the 868Mhz - this might potentially interfere with the Reolink Home Hub then - it advertises using a sub-1G frequency for communication between the Hub and the Reolink battery-doorbell
