Erratic SoC % in a very short time
Morning,
The last 3 days, I have noticed my SoC to be having a very erratic behaviour, that have not seen before. Rapid increases and decreases with the load not justifying such readings.
Any views on why this happens? Please see below screenshots from 16th, 17th and this morning.
Grateful for any replies.

Issues with SoC in almost all cases indicate not working communication to the battery.
