MQTT and Homekit

[wullimann]

Hi,

I configured a custom mqtt server to my switches that are already setup with homekit. The servers a stored properly in the devices but the mqtt server logs don't show any activity from the switches to connect the server. Do you know if mqtt action is disabled when setup with homekit?

Can you describe the steps you took to set the devices up?

First I set it up for Homekit with my iPad. After it registered with my wifi I changed the mqtt server

meross setup --gateway 192.168.64.124 --mqtt 192.168.64.15:8883 --wifi-ssid xxxxxx --wifi-pass xxxxx 

I checked:

meross info --gateway 192.168.64.124
Getting info about device with IP 192.168.64.124

}
Got response: {

        triggerx: [],
        timerx: []
      }
    }
  }
}

But there is ablosutely no activity in die mosquitto log:

/var/log/mosquitto$ sudo tail -f mosquitto.log 
1610522949: Saving in-memory database to /var/lib/mosquitto/mosquitto.db.
1610524750: Saving in-memory database to /var/lib/mosquitto/mosquitto.db.

The MQTT Explorer on my Mac shows no activity either on the server. Since my setup differs from the setup in the docs here in terms of homekit, I deduced that this is the catch.

I would suggest you follow the guide first to make sure that your MQTT broker is configured correctly and you can control the device by sending

{
    "header":{
        "from":"/appliance/2009091137638951852148e1e93155f4/publish",
        "messageId":"7c2834f83f9cc5b1c7ae1049280a9f3f",
        "namespace":"Appliance.Control.ToggleX",
        "method":"SET",
        "payloadVersion":1,
        "sign":"e48c24e510044d7e2d248c68ff2c10ca"
    },
    "payload":{
        "togglex":{
            "channel":1,
            "onoff":1
        }
    }
}

to /appliance/2009091137638951852148e1e93155f4/subscribe

Once you're happy it works, try again to setup with Homkeit and then MQTT
