Depth of Discharge 30-88%

Issue Description

Hello,

Since updating my Marstek Jupiter C Plus to firmware version 140, the official Marstek App allows setting the Depth of Discharge (DoD) value from 30% up to 90%.

However, via this MQTT integration, the maximum allowed value is currently capped at 88%.

Could you please update the upper limit to 90%? Alternatively, could you point me to the file where I can adjust this limit locally myself in the meantime?

Thank you!

#edit: from 30% up to 90%. not 10% up to 90%.

Thanks for the report — I can take a look, but I’ll need logs to debug this.

Please add:

1. hm2mqtt logs (DEBUG)

   • Home Assistant → Settings → Add-ons → hm2mqtt
   • In the add-on configuration, set:
     • log_level: debug
     • debug: true
   • Restart the add-on
   • Then paste the relevant log excerpt here (around the time the problem happens)

2. Hame Relay logs (DEBUG)

   • In the Hame Relay add-on, enable debug logging (log level debug) and restart
   • Paste the relevant log excerpt here

Important: please redact/replace any IDs (deviceId/MAC, tokens, MQTT credentials, etc.) before posting.
