Sum helper from „Group“ lost unit since last update and graph is not showing correctly

[3gfisch]

The problem

Hi, i had a working sum helper from the group section to sum up my home power usage in watts (PV power + Grid power) both single sensors show up correctly but since the last 1 or 2 updates the unit is missing from my sum and therefore also the graphs look strange. See screenshots. I could not find a setting for the unit so I don’t know how to fix it, also I don’t want to lose data of this sum and make a new one in yaml (running since a year) Thanks a lot

Problem:

Helper configuration:

The two inputs look ok as far as i can see:

Had still the same problem after the newest update today. But i found a temp fix: in the group option i added an other power sensor (a Shelly which was off) to the sum. Applied it. Then the unit appeared again. Then i removed it again and the unit stayed but after reboot was gone again :( Then i tried to swapped the order of the 2 sensors that the Shelly is first then my sensor which is a sum helper also, but still the unit is gone after reboot :(

Any ideas what i could try or how to debug the problem further? Does it try to make the unit of this helper before the other helper is up and running or something like this? Thanks

It is old issue... more than 6 months, it is annoying :-/ I have the same at any reboot for some Group Sensors (all energy sensors in W). Any update in the group configuration as "Ignore non-numeric" switch rebuild the Group Sensor to expected behavior with the right unit. Most of the Sensors come from ZWaze or Shelly. I may come from device class not set but how it is possible and how to fix it or force ?

Found a workaround for me, i renamed the entity *_back and disabled it. Made a new sum with the combine helper and gave it the old entity name. Since its only power and from this energy is integrated with an other helper it looks like my long therm energy statistics still work :)
