inverters image

This is a Hassio addon to monitor voltronic axpert inverters through USB and publish the data as JSON to an MQTT broker. It publishes the data to 3 topics:

  • 'power/axpert' for the parallel data (some of these values seem to be only for the connected inverter even though they are returned by the parallel data command)
  • 'power/axpert_settings' for the configured settings
  • 'power/axpert{sn}' for the data from the connected inverter (configurable, {sn} is replaced with the serial number of the inverter)

You can then configure the sensors in Home Assistant like this:

sensors:
  - platform: mqtt
    name: "Power"
    state_topic: "power/axpert"
    unit_of_measurement: 'W'
    value_template: "{{ value_json.TotalAcOutputActivePower }}"
    expire_after: 60

The values published on 'power/axpert' are:

  • SerialNumber # of the first inverter in the parallel setup
  • TotalAcOutputActivePower
  • TotalAcOutputApparentPower
  • TotalAcOutputPercentage
  • BatteryChargingCurrent
  • BatteryDischargeCurrent
  • TotalChargingCurrent
  • GridVoltage
  • GridFrequency
  • OutputVoltage
  • OutputFrequency
  • OutputAparentPower
  • OutputActivePower
  • LoadPercentage
  • BatteryVoltage
  • BatteryCapacity
  • PvInputVoltage
  • OutputMode
  • ChargerSourcePriority
  • MaxChargeCurrent
  • MaxChargerRange
  • MaxAcChargerCurrent
  • PvInputCurrentForBattery
  • Gridmode
  • Solarmode

The values published on 'power/axpert_settings' are:

  • AcInputVoltage
  • AcInputCurrent
  • AcOutputVoltage
  • AcOutputFrequency
  • AcOutputCurrent
  • AcOutputApparentPower
  • AcOutputActivePower
  • BatteryVoltage
  • BatteryRechargeVoltage
  • BatteryUnderVoltage
  • BatteryBulkVoltage
  • BatteryFloatVoltage
  • BatteryType
  • MaxAcChargingCurrent
  • MaxChargingCurrent
  • InputVoltageRange
  • OutputSourcePriority
  • ChargerSourcePriority
  • MaxParallelUnits
  • MachineType
  • Topology
  • OutputMode
  • BatteryRedischargeVoltage
  • PvOkCondition
  • PvPowerBalance
  • MaxBatteryCvChargingTime

The values published on 'power/axpert{sn}' are:

  • BusVoltage
  • InverterHeatsinkTemperature
  • BatteryVoltageFromScc
  • PvInputCurrent
  • PvInputVoltage
  • PvInputPower
  • BatteryChargingCurrent
  • BatteryDischargeCurrent
  • DeviceStatus

I have 3 inverters in parallel and a raspberry connected to 1 of them with a USB cable . Linux doesn't seem to recognize it as a USB to Serial device and it only shows up as /dev/hidraw0.

A description of the serial communication protocol can be found here

Install

Add https://github.com/MindFreeze/home-assistant-addons to the addon store repositories and you will get a Axpert Inverter listed there. Note that this assumes the inverter is /dev/hidraw0. If you have other USB to Serial devices connected this might be wrong.
