2 years ago As a workaround I commented this lines and all my motion sensors starts to show right graph https://github.com/StyraHem/ShellyForHASS/blob/a8fc34ce016462f12b73d5e9871fb38553859376/custom_components/shelly/binary_sensor.py#L169-L172
Btw, do not know is it have negative effect on other sensors or not. But binary sensors shouldn't have units of measure.
Environment
Describe the bug
Shelly Motion sensor exports a unit_of_measure property which is null. This trips up the history_graph component which now tries to display a line graph rather than a binary state graph. This report applies to all the binary sensors exported by Shelly (vibration, connected status).
Steps to Reproduce
Click on the entity to bring up details, the graph is a line graph (with no data because value is not numeric)
Expected behavior
Compare to a sonoff motion sensor which does not export unit_of_measure and displays graph correctly

Additional context
This has shown up recently, within the last few upgrades. It might have been a change to the history_graph that triggered it because I do not see changes to SHelly Motion. But I think root cause is the incorrect export of unit_of_measure.
