Works also for a Powerqueen 24V 100Ah #1

Just to let you know: I used your script on the bms of a Powerqueen 24V 100Ah instead of 12V, it works perfectly :)

Thank you!

dmytro-tsepilov commented 4 weeks ago

Thank you for your feedback! It's very helpful!

Also using this on Powerqueen 24V 100Ah succesfully, however with 1 issue.

When current goes out of the battery it is reported like 4 million Amp !

@Hannibal2206 Hi, thanks for feedback. I uploaded new version v0.1.2, The current value should be fixed there.

Try it, and let me know please.

Mediacj commented 2 weeks ago

Thanks for the update!

I indeed also had that high current during discharge, installed the update, and now it shows -0.0. Is there no value available during discharge? And during charging, does it now stay at 0.0

dmytro-tsepilov commented 2 weeks ago

@Mediacj Hm, that's strange. Can you please run script with --verbose option, during battery charging or discharging (with some load) for more information. And post output here, please.

For example: python main.py AA:BB:CC:DD:29:11 --bms --verbose

Mediacj commented 2 weeks ago

Ok I will do that!

Mediacj commented 2 weeks ago

I was mistaken, sorry. The value in the JSON is correct, but I think there is an issue with my Home Assistant template sensor! So everything is ok now, thx!

During charge:

Yes, I see exactly the same behaviour !

Thanks for the quick update !!

dmytro-tsepilov commented 2 weeks ago

@Mediacj Thanks for verbose data. So it looks good now :) "current": 2.65 - when charging and "current": -22.2 - when discharging, the negative value

Hannibal2206 commented 1 week ago

Hi,

Thanks again for your code to start with and alsof or the quick fix on the negative current issue

I would like to express my gratitude, is there a way I can donate to you for this ? via Paypal maybe ?

BR, Han
