HA version 2022.11.1
HA companion version 2022.10.1
This problem has been going on since I started using HA, about 3 months ago.
An Ipad is running the companion app. A dashboard is showing temperature graphs for 4 rooms.
Every now and then, all 4 graphs are identical. If I switch to a different dashboard and back again, the graphs are updated with the real values.
The solution is probably to use a “better” card than the sensor card, but I thought I’d report this in case someone else is experiencing the same problem.
