No Entities in Home Assistant

[dajomas]

Python: 3.12.2 HA Core: 2024.2.0 (on a VM) SmartMeter: Landis&Gyr E350 (DSMR 2.2+) P1 connected to an RPi via serial splitter (used ser2net in the past which worked but ser2net was not stable enough)

I created the following compose.yaml file:

version: "3"

services:
  mqtt4dsmr:
    image: "ghcr.io/antonijn/mqtt4dsmr:latest"
    environment:
      MQTT_HOST: "***"
      MQTT_PORT: "1883"
      MQTT_USERNAME: "***"
      MQTT_PASSWORD: "***"
      DSMR_VERSION: V2_2
      SERIAL_SETTINGS: V2_2
    devices:
      - "/dev/serial/by-id/usb-FTDI_FT232R_USB_UART_A50285BI-if00-port0:/dev/ttyDSMR"
    restart: always

via MQTT Explorer, I can see a topic dsmr which only contains a status with value online but I can't find any entries in the homeassistant topic and in HA, I can't find any dsmr entries either.

Did I miss anything? Where should I find the dsmr entries in HA?

Thanx for your help.

1. What does docker logs mqtt4dsmr report?
2. Are you using the MQTT integration in Home Assistant? Are other MQTT devices working as expected?

/srv/mqtt4dsmr $ docker logs mqtt4dsmr-mqtt4dsmr-1
2024-02-21 11:49:12,346 INFO Using mqtt4dsmr v0.9.4

And yes, I am using the MQTT integration succesfully with Zigbee2MQTT (2 instances, over 80 devices), ZWave JS UI (formerly Zwave2MQTT) and ITHOWiFi

I suspect this has something to do with the serial settings. If you set the environment variable LOG_LEVEL=DEBUG in the container, do the logs show that any serial messages are received?

I suggest you try SERIAL_SETTINGS=V4 or even SERIAL_SETTINGS=V5.

The device will only show up in Home Asssistant after a serial message is successfully read from the P1 port; only then does the application know exactly which information is available. Perhaps I should make this situation easier to troubleshoot - have the device show up in Home Assistant with a message that it is not receiving messages. Something like that.

[dajomas]

I set SERIAL_SETTINGS=V5 in compose.yaml and export LOG_LEVEL=DEBUG on the commandline and ran docker compose up -d

/srv/mqtt4dsmr $ docker logs mqtt4dsmr-mqtt4dsmr-1
2024-02-21 17:30:36,110 INFO Using mqtt4dsmr v0.9.4

2024-02-21 17:30:36,139 INFO Connected to broker
/srv/mqtt4dsmr $

And nothing changed in MQTT and HA

The LOG_LEVEL=DEBUG option must be specified in compose.yml, sorry for not making that clear. Have you tried serial settings V4? I suspect we're dealing with the DSMR 4 version of this meter.

[dajomas]

I'll give that a try now. On the meter it actually says DSMR 2.2+

I finally got it working!

Problem was on my end: a fault cable. Replace the P1 cable and all is working now. DMSR_VERSION and SERIAL_SETTING are set to V2_2 and I have a DSMR Smart Meter device in the MQTT devices list
