Thanks Andrew,
Great spot on the power metering - I couldn’t wait to use it so I’ve implemented it myself and logged a PR. It’ll be interesting to see what other devices Drayton come out with, an underfloor heating controller’s been promised for a while (it was in the app release notes), and support told me it was going to be for wet systems, looks like it’s available in Germany).
I was wondering - is there a reason there’s a channel for “Zigbee Connected”? Would it make sense to use that for setting the thing Status to offline, e.g. when a device is out of range, or a smart plug is powered off or trv/roomstat battery flat? From what I can see it’s offline when "DisplayedSignalStrength": "NoSignal", or RSSI/LQI are null.
Finally I’m on OH3, and seeing the error logged about Representation property 'networkAddress' of discovery result for thing, but it seems benign, and I’ve not spotted any other issues.
