Tool written in GO for reading metrics from Sofar LSW-3 and writing results into MQTT topics. Program queries logger modbus port in infinite loop and sends data into MQTT topics (e.g. mosquito in HomeAssistant).
- Download go 1.19
- Clone this repo
git clone git@github.com:kubaceg/sofar_g3_lsw3_logger_reader.git
- Go into project directory
cd sofar_g3_lsw3_logger_reader
- Copy example config
cp config-example.yaml config.yaml
- Edit
config.yaml
in Your favorite editor, fill all required stuff - Build program
make build
or build for ARM machines e.g. raspberryPimake build-arm
- Run
./sofar
orsofar-arm
Data will be sent into MQTT topic with name {mqttPrefix}/{fieldName}
where:
- mqttPrefix is value defined in
config.yaml
e.g./sensors/energy/inverter
- fieldName is measurement name, all available measurements are described in
adapters/devices/sofar/sofar_protocol.go
, e.g.PV_Generation_Today
Full topic name for given example values is /sensors/energy/inverter/PV_Generation_Today
.
Additional field is All
which contains all measurements and their values marshalled into one json.
This is based on program written by @sigxcpu76 XtheOne/Inverter-Data-Logger#37 (comment).
