Hi,  
I use two Shelly 1PM Gen 4s and one EM Mini Gen 4 to measure my PV inverters. On v3.80~27, they are recognised most of the time and work satisfactorily. When I install ~33, they are no longer displayed. I thought they weren’t dimmable!?

Furthermore, even on ~27, I have the issue that the EM Mini’s values aren’t included in the solar calculation in my VRM dashboard, and therefore not in the forecast either. Please find the screenshots attached.

Hütte PV is measured by the 1PM Gen 4, while Hausdach is our main Fronius PV system.

It would be great to get any hints or a fix in the future. Thanks a lot!
