Zigbee dimmer wrong kwh value after domoticz update

[kshesq]

Hello domoticz friends,

I noticed something strange with 2 zigbee dimmers I own. they are ROBB Smart 400w dimmers and I use them to light 2 chandeliers I have hanging in the living room.

They are connected through ZigBeeforDomoticZ plug-in and recognized as ROB_200-011-0 and I get the widgets: ROB_200-011-0_Power, ROB_200-011-0_Meter and ROB_200-011-0_Ampere
After installation the current power values are correct. when running 8 60w bulbs at 50% the power output shows about 240w and at 25% I get 120w
I am aware that the bulbs at 100% would require more power than the 400w dimmer would supply but I never run the lights at more than 50%.

After updating domoticz (2026.3) these outputs change with roughly a factor 10. So running the bulbs at 50% gives me a value of 2400w.
I can fix this by removing the dimmer from domoticz and ZigBeeforDomoticZ plug-in and then connecting it again in ZigBeeforDomoticZ plug-in and re-create it in domoticz. Only recreating the widgets in domoticz doesn't work.

This happened now in the last 2 domoticz updates (also to version 2026.2). Before that I don't know because I only have the dimmers since 2 versions ago.
Any help in this would be very appreciated.
