"history-graph" card is not combining sensors with same unit on the same graph


For a reason I don’t understand, sensor “avgpower30s” is defined with units “W”, but it does not display on the same graph as the other sensors with the same units “W”.

What am I missing ? Running Home Assistant 2022.2.7

The top graph has no unit of measurement. Did you recently change the unit of sensor.avgpower30s to “W”?

If so the graph will eventually update (24 hours).

No I didn’t change any units on that graph. I deleted “home-assistant_v2.db” today because I changed another unit from C to °C and the mix of the two units did not combine into a single graph. I noticed that behavior right after deleting the DB.

But no change on this “W” graph. Should I expect to still wait 24hrs for it to fix itself ?

Interestingly enough, changing “hours to show” to something shorter like “4 hours” fixes the problem. I think one of the first sample, after deleting the DB, bears not unit.

Like you said, it should clear itself in 24 hours or so.

Confirmed, gone after 2hrs.
