edit - found my solution i had to choose string and now it works
i Installed Openhab 3 and Mosquito as Docker Containers, everything is connected and working.
So i started to add some Wlan Sockets ( NOUS A1 with Tasmota installed), i wars able to get the On/Off working.
Now i wanna “install” other Stats like e.g. Power / Uptime …
But i think i do something wrong her.
I add Screenshots about my config
Here are the Stats i want like Sensor → ENERGY → Total
So i created a Channel (under my Socket Thing)
and then a item - with the JSON but i get NULL as result (i used total her because there is a definitely a reading (see picture 1)) - and i think somewhere here is my mistake…
