Firmware update causes messed up sensor IDs

[RustyDust]

With a recent firmware upgrade Sonnen changed the IDs for some sensors returned by their API. Since the integration creates sensor names based on those IDs this may have a major impact on collecting stats and running automations.

Example

sensor.sonnenbatterie_xx_meter_production_4_1_w_l3 may now be sensor.sonnenbatterie_xx_meter_production_0_1_w_l3

Note the difference in the numbering right after production_.

Solution

To check whether you are affected

• go to "Settings -> Devices & Services -> SonnenBatterie -> xx Entities"
• check for entities
  • marked as "unavailable"
  • marked as "disabled"
• if you see those entries, check the "disabled" ones for candidates that might replace the "unavailable ones"
• enable the disabled sensors you want to use
• verify the newly enabled sensors provide the data you want/need
• check your helpers and automations and replace the old values with the newly enabled sensors.
