SHELLY PLUS 1 AND ADDon TEMPERATURE

hello everyone, it’s been days now that I’ve been trying to make the temperature control of shelly plus 1 work I OPENHAB but unfortunately its ADDON is not recognized… Does anyone know how to do it?

also the Raspberry 3 is not found on the net so I can’t get there to bring us images for floor plans
Thank you all for your help

A bit more information about your installation (openHAB and Java version e.g.) would be very helpfull.

hi…according to your experience the problem can be dictated that shelly plus1 and addon is powered by 230v?
I also downloaded a beta bilding from Shelly and I didn’t solve it… that is, I don’t see the temperature probes on the ADDON
