Grafana Value Mapping with Current Boolean Value

[Andrzej15]

HI Guys,

i've got some trouble with the Grafana Value Mapping for the Singlestat Visualization.

i use the Shelly relay to proof if the socket is on or off. I've got a json value which my IoBroker can already read. Works fine.

So in Grafana i only see the Value true or false. But i couldn't match them with the value mapping. Nothing Changes.

Does anyone have an idea? i am new in Grafana, so i am sorry if this is a bad question....
