I emailed Swann a few weeks ago about their SwannOne smart home stuff, and finally got a response, here’s the exchange:
I would like to know what protocol the SwannOne sensors (door/window and
motion) use? If it is Zigbee, do they use the HA 1.2 profile?
And the response:
Thank you for contacting Swann Technical Support.
With regards to your concern, the answer is Yes, our system uses Home Automation (HA) 1.2 profile.
They do a twin pack of door sensors for £44.99 making them £22.49 each which so far seems the cheapest I have found. (http://www.maplin.co.uk/p/swannone-wireless-windowdoor-sensor-twin-pack-a63tr).
The motion/temperature sensor doesn’t seem too badly priced either at £34.99 (http://www.maplin.co.uk/p/swannone-wireless-pir-motion-and-temperature-sensor-a61tr)
These also appear to be available from Screwfix.
They word it as if it only works with their hub but given that it’s using the Zigbee HA 2.1 profile I suspect it’ll work with ST.
Anyone tried any of these yet?
