Huawei SUN2000 monitoring

If you want a simple and reliable solution for monitoring SUN2000 inverter and only collecting parameters to InfluxDB database I’ve added a support for this inverter in my hard.

The daemon is written in Rust and doesn’t need any special python/perl dependencies to work.

The SUN2000 can expose RS-485 data via internal WiFi interface or even (with newest firmware) via Smart Dongle-WLAN-FE.
All interfaces are well described here in this post:

If you build the hard, the following minimal config is needed to connect to inverter and pass the data to the InfluxDB:

[general]
log=/var/log/hard.log
influxdb_url=http://127.0.0.1:8086
disable_postgres=1
disable_onewire=1
disable_webserver=1

[sun2000]
host=192.168.200.1:502
