I have looked and can’t find an idiot’s guide.
Everything was working fine but now for the last month pretty much have not had any readings come through.
You don’t. It is no longer needed. Assuming your Home Assistant version is up to date.
All the energy sensor needs to appear in the Energy dashboard is a unit_of_measurement in kWh or Wh, a device_class: energy, and a state_class: total_increasing or total.
Entity sensor.gas_consumption_dcc_sm_profile_reads (<class ‘custom_components.hildebrandglow-dcc.sensor.GlowConsumptionCurrent’>) with state_class measurement has set last_reset. Setting last_reset for entities with state_class other than ‘total’ is not supported. Please update your configuration if state_class is manually configured, otherwise report it to the custom component author.
