DeyeInverter

Small utility to read data from DEYE Inverters through the Solarman Datalogger. Works with S/N 17*

Tests indicate that the full ModBus is available through the TCP connection. Probably this can lead to modifying Inverter Configuration via TCP calls.

Thanks to @fjcarretero https://github.com/fjcarretero for his incredible support on understanding the data from and to the datalogger. Thanks to @xtheone https://github.com/XtheOne for his original V4 reader that was an inspiration (and I borrowed some code).

Configuration

Edit the config.cfg and enter the following data:

[DeyeInverter]
inverter_ip=192.168.X.XXX
inverter_port=8899
inverter_sn=17XXXXXXXX
installed_power=XXXXX #power in Watts e.g. for 4.5kW write 4500
mqtt=1  # set to 1 for MQTT output, 0 for JSON output.
mqtt_server=192.168.X.X
mqtt_port=1883
mqtt_topic=XXXXXXXXXXXX
mqtt_username=
mqtt_passwd=

Known Issues

The inverter is not fast enough to answer, you can get timeouts if you query it too often.

Contrib

Python is not my strongest suite, feel free to suggest, rewrite or add whatever you feel is necessary.
