Hi,

I am using 10 different units of HS110 and monitor their respective datas through home Assistant integration.

I have a problem with one device,  HS110 v2 with firmware 1.5.6 is working fine as you can see on the first graph here under but has randomly a surge in the values as you can see on the 2nd picture 515350 Kwh.

The other HS110 are performing fine without sudden unexplaied surge.

Hard reset done but still those surge occurs.

device connected is a FAN

thanks for your help
