    I have setup cgateweb wtih MQTT , CGATE and Home Assistant recently.

    Am wondering if any other topics can be subscribed to other than lighting?

    I'd like to be able to read CBUS temp sensors from CGATE since its posting that data regularly on measurement app. I also have irrigation.

    Anyone have any luck with this?

    Regards,

    BenC

    I did mine slightly differently so i could get the temp sensors and other items working:
    Cbus --> HomeBridge (Homekit) --> Home Assistant

    Works well, and i get the full history of temperatures (interesting to compare in vs out over time).

    I also have integrations going the otherway, so I can trigger sonos to play/pause/next from the eDLT for example based on certain groups turning on/off/level.

    Still a work in progress, but getting there. Best bit is it works on the SHAC touchscreen (after you update the firmware to the latest version of android via the OEM's website), so have now ditched the SHAC in favour of this.

    Assuming you are using the CGate to MQTT from https://github.com/the1laz/cgateweb
    Steven has only coded it to work with the lighting application - 56

    There was a fork created to work with HVAC application - https://github.com/mminehanNZ/cgateweb which you may be able to tweak to work with the temp application or if you have a SHAC/NAC you can publish your temps via MQTT with a LUA script.
    Code:
    -- Get temperature and units of channel 1 of sensor 1 on the local network
    -- temp is a float and units is a string (eg '°C')
    
    temp_rack = GetCBusMeasurement(0,166,1)
    temp_indoor = GetCBusMeasurement(0, 166, 2)
    temp_outdoor = GetCBusMeasurement(0, 166,3)
    temp_studio = GetCBusMeasurement(0, 26, 1)
    mqtt = require("mosquitto")
    
    client = mqtt.new()
    --log("created MQTT client", client)
    
    client.ON_CONNECT = function()
    --  log("connected to MQTT broker")
            local qos = 1
            local retain = false
      local mid = client:publish("temperatures/studio", temp_studio, qos, retain)
            local mid = client:publish("temperatures/rack", temp_rack, qos, retain)
            local mid = client:publish("temperatures/indoor", temp_indoor, qos, retain)
            local mid = client:publish("temperatures/outdoor", temp_outdoor, qos, retain)
    
    end
    
    client.ON_PUBLISH = function()
        client:disconnect()
     
    end
    
    broker = 'X.X.X.X' -- Broker ip adress
    client:connect(broker)
    client:loop_forever()

    Thanks @Damaxx !! You have just opened my world to new possibilities!

    This took all of 5 seconds to setup on my SHAC and post the temps every minute. There is so much automation to be done now ...:D

    could this be modified to publish everything to an mqtt server to send and receive payloads?

    this would make cgate and an mqtt intermediary redundant

    I've got the first two items worksing but not HA. Are you using the Homebridge MQTT plugin to get Homebridge to talk to HA or there another option?

    I really struggle with JSON, any edits can't be saved due to some error. On the face of it the syntax looks simple, structred but I'm clearly not 'getting' it. This it the instructions I've tried:
    https://github.com/cflurin/homebridge-mqtt#readme

    Thanks,
    Rob

    Have a look at this one zei20t - https://github.com/Nick-Adams-AU/5500SHAC-Cbus2MQTT

    So the SHAC will talk to a MQTT broker directly?

    Hi all,

    Managed to get CBUS -> Cgate -> HomeBridge -> HA, and all without any lag/delay on an RPi4 to control lights and blinds. See https://github.com/anthonywebb/homebridge-cbus/ for full list of support devices.

    Steps to reproduce:
    1. Install Homebridge: https://homebridge.io/
    2. Install HA: https://www.home-assistant.io/
    3. Install Homekit Controller on HA: https://www.home-assistant.io/integrations/homekit_controller/
    4. Connect the Homebridge to HA via the Homekit Controller on HA.
    5. Connect CBUS to Homebridge: https://github.com/greiginsydney/Homebridge-cbus-installer
    6. On HA, go to Configuration -> Integrations -> Homekit Contoller -> Reload
    7. Give it a minute, and your devices should appear in HA.
    8. (Optional) Install the Homekit integration on HA: https://www.home-assistant.io/integrations/homekit/
      1. The connection QR/code given by the HA integration is the one you should connect with in your iOS app.
    Some notes:
    • I have found it is essential to connect Homebridge and HA (step 4), before completing step 5. Once the CBUS devices are loaded onto the Homebridge in step 5, initialising a connection between Homebridge and HA becomes impossible (granted, this could be due to the complexity of my local cbus network).

    i ran HA and MQTT which was easier to manage than using homekit (in my opinion)

    pretty much any device or connection could stop and start and everything would pickup where it was again.

    now using a SHAC with Narkov's script to push all comms via MQTT and into HA removing the need for the cgate server.
