Marstek Venus E2 with hame-relay and hm2mqtt

[eddieb]

As discussed in an other topic.

I have my Marstek Venus E2 working with hame-relay and hm2mqtt working all in docker ...

install https://github.com/tomquist/hame-relay

compose.yaml

Code: Select all

services:
  mqtt-forwarder:
    container_name: hame-relay
    image: ghcr.io/tomquist/hame-relay:latest
    restart: unless-stopped
    dns_search: .
    volumes:
      - ./config:/app/config
    environment:
      - LOG_LEVEL=info
networks: {}

Code: Select all

cat config.json
{
  "broker_url": "mqtt://your-broker-ip",
  "username": "your-marstek-user",
  "password": "your-marstek-password",
  "inverse_forwarding": "true"
}

install https://github.com/tomquist/hm2mqtt

compose.yaml

Code: Select all

services:
  hm2mqtt:
    container_name: hm2mqtt
    image: ghcr.io/tomquist/hm2mqtt:latest
    restart: unless-stopped
    environment:
      - MQTT_BROKER_URL=mqtt://your-broker-ip:1883
      - MQTT_USERNAME=''
      - MQTT_PASSWORD=''
      - MQTT_POLLING_INTERVAL=60
      - MQTT_RESPONSE_TIMEOUT=45
      - POLL_CELL_DATA=true
      - POLL_EXTRA_BATTERY_DATA=true
      - POLL_CALIBRATION_DATA=true
      - DEVICE_0=HMG-50:0019aa0d4dcb # 12-character MAC address
#      - DEVICE_0=HMA-1:0019aa0d4dcb # 12-character MAC address
networks: {}

The DEVICE must be HMg-50 for VENUS E2
the MAC must be the Bluetooth MAC address of your battery

from now on hm2mqtt polls the Marstek cloud every minute and sends data over mqtt
as I had MQTTAD running, some 94 devices are created in domoticz !

- don't be surprised to see some timeouts on polling
- don't be surprised to see some very strange values in the TEMPERATURE devices
