Solis to Web

Gets Solis Inverter data and stores as web pages

Tested with Solis 4G Mini Inverter

• Uses MQTT, subscribes to inverters 'update' topic and gets messages with Paho
• Messages are stored as json files
• Creates index.html showing yield, power, etc and graphs with Plotly
• SolisCloud not needed, data stays local

Requirements

A Solis Data Logger stick (Solis-S2-WL-ST), a MQTT broker (Eclipse Mosquitto) and optionally a web server.

To run Mosquitto with Docker, see here.

Make sure Data Stick is inserted in the Inverter and can connect to the MQTT broker (Mosquitto).

Goto webadmin page of Data stick:

• Set MQTT Broker under to "Advanced > Mqtt Settings"
• Check "Status > Remote Server Information", it should say "Connected"
• Also get your "Device serial number"

Configuration

If config.py does not exist yet, copy defaults from config.py.dist to config.py first.

Edit config.py:

• set BROKER_HOST
• (optionally) set auth with BROKER_USERNAME and BROKER_PW, remove settings to disable
• change TOPIC to your device serial number

Remeber check for config changes after updating (see commits)

NOTE: Environment vars will overwrite config settings

Running

Either use uv or Docker.

If you do not have uv, check installation. It will take care of depedencies (e.g. Paho and Plotly modules).

Output html and json files are stored in 'www' dir (optionally use e.g. NGINX to serve).

uv

Run in background and log to solis.log: ./run.sh

To run in foreground: uv run main.py

docker

Run latest image from GitHub:

docker run --volume "$PWD/config.py:/app/config.py" --volume "$PWD/web:/app/web" ghcr.io/mkorthof/solis-mqtt-to-web:latest

Or use env vars e.g.:

docker run --env BROKER_HOST=1.2.3.4 --env BROKER_PORT=321 --env TOPIC="/ginlong/ABCDEF1234/update" --volume "$PWD/web:/app/web" ghcr.io/mkorthof/solis-mqtt-to-web:latest

To run both Mosquitto and Client (detached):

./docker-run.sh

docker compose

Run Mosquitto and Client using compose (detached):

./docker compose up -d
