Thanks.
Shall look at the flow soon.
It is only going to be 3 maybe 4 colours.
I've installed your ui_level
node. That seems to be working fine.
Oh, somewhere - recently - I remember being told that I can send "text" payloads into the gauge and it will parse the "text" as a number.
So I can send "88" and it will be parsed by the gauge as 88 (number).
But I may be dreaming that someone said that.
