Solar-Log


The solarlog integration uses the open JSON interface on Solar-Log PV monitoring systems to allow you to get details from your Solar-Log device and integrate these into your Home Assistant installation.

Before being able to use the integration, you have to activate the open JSON interface on your Solar-Log device. This can be activated from the Configuration | System | Access control menu of your Solar-Log device. When activating the interface, a red warning triangle with security information and risks is displayed.

The solarlog integration uses the default host address “http://solar-log” if you don’t specify a host. If your device isn’t accessible on this address, use its IP Address instead.

The open JSON interface is deactivated by default. To activate the open JSON interface, a user password must first be set. The password isn't needed for accessing the open JSON interface.

Configuration

To add the Solar-Log integration to your Home Assistant instance, use this My button:

Additional template sensor

In case you would like to convert the values, for example, to Wh instead of the default kWh, you can use the template platform.

# Example configuration.yaml entry for sensor template platform
template:
  - sensor:
    - name: "Solarlog yield day"
      state: "{{ (states('sensor.solarlog_yield_day') | float(default=0) * 1000) | round(0,default=0) }}"

Sensors

The following sensors are available in the library:

name Unit Description
last_update Time of latest data update.
power_ac W Total output PAC from all of the inverters and meters in inverter mode.
power_dc W Total output PAC from all of the inverters.
voltage_ac V Average voltage AC from the inverter.
voltage_dc V Average voltage DC from the inverter
yield_day kWh Total yield for the day from all of the inverters
yield_yesterday kWh Total yield for the previous day from all of the inverters.
yield_month kWh Total yield for the month from all of the inverters.
yield_year kWh Total yield for the year from all of the inverters.
yield_total kWh Total yield from all of the inverters.
consumption_ac kWh Current total consumption AC from all of the consumption meters.
consumption_day kWh Total consumption for the day from all of the consumption meters.
consumption_yesterday kWh Total consumption for the previous day from all of the consumption meters.
consumption_month kWh Total consumption for the month from all of the consumption meters.
consumption_year kWh Total consumption for the year from all of the consumption meters.
consumption_total kWh Accumulated total consumption from all consumption meters.
installed_peak_power W Installed solar peak power.
alternator_loss W Altenator loss (equals to power_dc - power_ac)
capacity % Capacity (equals to power_dc / total power)
efficiency % Efficiency (equals to power_ac / power_dc)
power_available W Available power (equals to power_ac - consumption_ac)
usage % Usage (equals to consumption_ac / power_ac)
The solarlog integration is using the sunwatcher pypi package to get the data from your Solar-Log device. The last five sensors are not reported by your Solar-Log device directly, but are computed by the sunwatcher package.
