Monitoring Cell Health- Home Assistant wizards

I am rubbish when it comes to HA. I have managed to get it running on a Pi400 and have started to use it to view the individual cell voltages and SoC to monitor the cell health.

I have managed to create a report (in History) which shows what I am after.

I am sure that there will be a way of exporting the actual values (to import into Excel), but I have no clue on how to do so. There's a few HA wizards here, so anyone want to throw a shekel to an ex-leper give me some advice?

Many thanks in advance.

My question is why? This is your type of deviation? This system have 10 years warranty so why bother to do it it now when it's in beginning of its path. Regards

Since when has needing a valid reason ever been the rationale to do something? :-)

Take a look at this
