Datapoints and units

Datapoints and units

Available datapoints depend on the inverter type and on which values the inverter actually sends.

Main groups

In MQTT and in the JSON output you will mainly see these groups:

• RawData: original inverter replies and command answers
• EspData: device information, Wi-Fi and MQTT status
• DeviceData: mostly fixed inverter information
• LiveData: current live inverter values and DS18B20 temperature sensors
• Status: connection and status information

MQTT layout

With the normal MQTT topic layout:

• <MQTT topic>/EspData/<name>
• <MQTT topic>/DeviceData/<name>
• <MQTT topic>/LiveData/<name>
• <MQTT topic>/RAW/<command>
• <MQTT topic>/Alive
• <MQTT topic>/DeviceControl/Set_Command_answer

With JSON mode:

• <MQTT topic>/Data

If Home Assistant discovery is enabled together with JSON mode, the normal MQTT datapoint topics are still published as well.

RawData

Typical raw keys include:

• QPI
• QMN
• QPIRI
• QPIGS
• QPIGS2
• QPIWS
• QALL
• Q1
• CommandAnswer

This section is mainly useful when support or troubleshooting is needed.

Notes

• Not every inverter exposes every field.
• Some values may appear under slightly different names depending on the inverter family.
• If a field is missing on your device, that does not automatically mean something is wrong.
