I managed to get around to trying this plugin (with UI5). Thanks for making this!
It does most of the basics that I need (Boil & Off) plus some others that I've not tested yet (and unlikely to use day-to-day).
I am pleased to see that I can probably set up scenes with Advanced settings to set many other iKettle options (like temperature, warm-up, etc.), but I've not tried them yet.
The status in Vera updates nicely from "Kettle Idle" to "Boiling". I notice that when it reaches temperature, the status changes briefly to "Kettle Busy", before returning to Kettle Idle. I'm not sure why that is, or what it means. It is nice to see I can display this status text in HomeWave too, but I'd suggest removing the unnecessary Kettle prefix, so that it is simply Idle, Boiling, Busy.
I did try to set up a basic scene to trigger when "Device is boiling", but unfortunately this didn't trigger. Is that not implemented yet?
Great work so far.
