    I seem to have solved my problems, here's the docker file:

    version: "3.9"
services:
  espruinohub:
    image: espruino/espruinohub
    hostname: espruinohub
    container_name: espruinohub
    privileged: true
    environment:
      - TZ=Europe/London
      - NOBLE_HCI_DEVICE_ID=0
    network_mode: host
    volumes:
      - /home/pi/espruinohub/config.json:/data/config.json:ro
    restart: unless-stopped

  node-red:
    image: nodered/node-red:latest
    environment:
      - TZ=Europe/London
    ports:

    network_mode: host
    volumes:
      - node-red-data:/data
    restart: unless-stopped

    volumes:
      #- ./mqtt/config/:/mosquitto/config/

      - mqtt-data:/mosquitto/data/
    network_mode: host
    ports:
      - 1883:1883
      - 9001:9001

volumes:
  node-red-data:
  mqtt-data:

    I need to find the folder where to store the Espruino web pages.

    I have wrote my own docker compose file now which works quite well, but one question about the config.json:

    "mqtt_host": "mqtt://localhost",
  "//mqtt_options": {
    "username": "user",
    "password": "pass",
    "clientId": "clientid"
  },

    if I have an open MQTT broker, do I just omit the username and password fields?

    There are like 20 devices in range, I can't really understand what is the problem.
    I will probably reinstall everything again.

    Great I will give it a try, I want to see if it can pickup the light pulses of my energy meter.

    I think we are missing each other, yes exactly I want to use the EspruinoHub installed on my Raspberry so that I can connect remotely from my laptop (which is far away from the BLE sensors) to the ide and then program the sensors via the WebBluetooth option.
    Yes I could do the same thing via SSH into the box and run the commandline but this is not always possible because of firewalls and other controls.

    I seem to recall that not having SSL enabled on webpages doesn't allow the WebBluetooth dialog to be available?

    Wow that is amazing, I am guessing the dynamic range is not that great?

    Yes but that was my point, you should mention that in the manual that without SSL is not going to allow.
    Yes of course I can use the public web version which has SSL.
    Cheers.

    Hi there,
    I noticed that the Espruino Hub software is installed without SSL certificate.
    Thus it is unable to connect via Bluetooth.
    Any instructions available to add https?
    Cheers.

    Hi there, this simple code gives me a

    should it not just work in the web as in the console?

    Hi there,
    I have the Espruino Puck Lite and would like to know when I call the Puck.light() which pins is reading?
    Do I always need to add a light dependent resistor?
    Cheers.
