Solar2MQTT can forward raw inverter commands. This is powerful, but dangerous.
Warning: commands are not syntax checked. Wrong commands can misconfigure the inverter.
Send commands to:
<MQTT topic>/DeviceControl/Set_Command
Read the answer from:
<MQTT topic>/DeviceControl/Set_Command_answer
The latest answer is also stored in:
RawData/CommandAnswer
Open Debug and use the Command Sender field.
Typical PI serial examples:
QPIQMNQPIRIQPIGSQPIGS2QPIWSQALLautodetect
- Simulator commands are not stored. After reboot the device returns to normal hardware mode.
- Raw command answers are visible in the Debug page, MQTT answer topic and debug report.
- If you are unsure about a command, do not send it.
If something does not work, start with wiring, settings and the Debug page.
Solar2MQTT is a community project. Some devices work immediately, others need a little troubleshooting and a good debug report.
