I was bemoaning the lack of Zigbee (or Z-Wave) smoke and CO detectors in the UK the other week, now that I'm on the lookout as my Nest Protect devices are expiring. Then spotted this in my local B&Q (equivalent of Lowe's or Home Depot, I guess).
Okay, the smoke version would fulfil what I need in this house, just without the link in to Hubitat. But then I did some Googling and found this that the smoke unit is known as a WST-630 which is compatible with their hitherto unknown ZigBee 3.0 module. A little more digging and there's a Z-Wave module too!
Anybody else found or played with these yet, or do I need to approach my "local ASM" as they advise? These look very interesting indeed.
