EDL21 - Wrong "Sum active instantaneous power" values

[olu12345]

The problem

Hello everyone,

I have the problem that as soon as the "Sum active instantaneous power" values ​​become negative, they jump to over 160,000W (positive value).

I have a photovoltaic system and during the day the values ​​are negative.

What version of Home Assistant Core has the issue?

core-2023.5.2

What was the last working version of Home Assistant Core?

core-2023.4.5 or below

What type of installation are you running?

Home Assistant OS

Integration causing the issue

edl21

No response

Anything in the logs that might be useful for us?

See line number 220, the value is at 164488.35 W.  

The correct value should be approximately -2500W

Additional information

The Meter is a DZG DWS7420.2.G2

Can you try to downgrade pysml to version 0.0.9 to see if it fixes the problem for you? I suspect that the workaround that was included in 0.0.10 for some DZG meters causes it.

I was able to reproduce the problem based on your log and released pysml version 0.0.11. It restricts the newly implemented DZG workaround to meters with serial numbers below 60000000: mtdcr/pysml@7c96d22?diff=unified

This is probably going to fix the problem for you, but in case 60000000 isn't the correct limit between devices containing the bug (probably pre-G2) and those without (probably G2), this value might need to be adjusted in the future to cover other users. It may also turn out to be unfeasible to use a single serial number to detect the presence of this bug.

@StephanU tagging you, to make you aware of this issue and the new version of pysml, because you handled the previous updates.
