Exception raised while updating state of sensors dc_status, system_mode and battery_priority (3 phase based system)

[trevordowling]

Describe the bug

An exception is raised while updating state of sensor dc_status, system_mode and battery_priority.

(Note: possibly this is not a bug in PredBat but more an issue with the GivTCT MQTT defs and the differences between the single and three phase systems)

Error entry is only generated if not running REST (as far as I can tell)

  ValueError: Sensor sensor.givtcp_{geserial]_battery_priority has device class 'None', state class 'None' unit '' and suggested precision 'None' thus indicating it has a numeric value; however, it has the non-numeric value: 'Grid' (<class 'str'>)

Looking these entities up in the Developer Status shows that they are listed as State 'unknown'

However reviewing the REST data dump (http://[192.168.1.147:6345/readData]) all three entities are visible and defined.

"System_Mode": "Grid_tied"
"DC_Status": "Normal"
"Battery_Priority": "Load"

Expected behaviour No MQTT error reported

Predbat version

v8.15.1

Environment details

GIV-3HY-11 GivEnergy battery module stack - 51.8 Ah | 20.29 kWh | (6 Packs) HAOS on PC hardware (dedicated)

Screenshots If applicable, add screenshots to help explain your problem. The most useful ones can be your battery chart, the Predbat HTML plan and your current settings in HA.

Log file Can you capture a log file from the time of the issue, debug mode is not normally required.

Predbat debug yaml file Enable debug mode and let Predbat run for one cycle. Look in the 'debug' directory under the Predbat add-on and take the .yaml file for the time period in question. Rename the predbat_debug_XX_XX_XX.yaml to predbat_debug_XX_XX_XX.yaml.txt and upload it to Github. This will allow your plan to be reproduced and also stores all your settings for review.

definitely looks like a givtcp issue not predbat

predbat is issuing the command to givtcp and for whatever reason its not working correctly for your inverter
