8 months ago I was just reading through a few issues - discovered that this part had changed (didn't realise)
'I assume you are using the wrong protocol_version (JK02 vs JK02_32S).' from @syssi https://github.com/syssi/esphome-jk-bms/discussions/329#discussioncomment-5926542
Updated and all works (love it when a plan comes together) - hopefully if anyone else has this.
Thanks for this
Hi,
I wonder if anyone can help - my ESP32 home and Home Assistant have been working perfectly on my bluetooth link to my JKB2A20S20P (via my ESP32 )- and then collecting that info into Home Assistant. It's been running for about a year, some time outs and usually ESP issues but nothing a simple restart wouldn't fix.
I don't know what happened, something broke - I thought it might be the ESP32 so I replaced it, still the same readings. I get perfect readings on bluetooth with the BMS app (so I know the BMS device is sending out ok readings)
When I connect the ESP Home - it connects to the bluetooth and the readings are spurious for example here's some of my logs (ignore the names, I never bothered to rename them but it all works fine) - Cell voltages appear to be reading but total voltage, temperature etc but others are just either zero or some weird number like this 'capacity remaining': Sending state 14286.84863 Ah' (max Ah normally is 272 so that number should be anything below that.)
here's a brief log capture from the ESP
Like I say, everything was working perfectly a couple of days ago, rebooted the ESP and then this ... replaced and still the same.
Any ideas what's broken and where - I've rebuilt the code and now updated Home Assistant as I was a few versions out of date - no difference, still the same.
