I am creating a new app for the LinknLink eMotion sensors, in particular the eMotion Pro and eMotion Ultra.
The test version is in the store [LinknLink | Homey](https://homey.app/a/ady.linknlink/test/)

Version 1.0.1 of the app is now live.

Have you setup the MQTT client on the sensor.
You will need to put Homey’s IP address in the settings.
Then set the user name and password that you have configured in the Homey app settings.

A bit offtopic: But can you tell us how well there sensors behave? By example compared to the Aqara Fp2?

And 192.168.50.88 is the IP address of Homey?
If you look in the Detected tab and tap on Get Devices, do you see anything in there?
Edit: Also make sure the device is not locked in the settings. I’m not sure if this is required, but mine are not locked.

The Pro version only has a basic zone feature, which is based on distance from the sensor.
But the Ultra is more like the fp2.
Generally I am pretty happy with them, but they are not perfect, as with any of this type of sensor.

While the Log is enabled, could you restart the app and then go back to the log page and after a minute or two, tap on Send Log.

Interesting the log shows the broker is having problems connecting to the selected ports.
Maybe try choosing different ports and restart the app again.

For your information, I have these plugins installed and they do not interfere with each other.
Mqtt broker
Mqtt client
Mqtt Hub

And you haven’t used the same port for those as the LinknLink app?

This is what I get when I restart the app:

Was there a particular reason you changed the default ports?
The ones I used as default shouldn’t interfere with anything else.
You could also try using the MQTT Broker that you have installed by switching of the option to use the built-in broker and then point the app and the device to that port and credentials. No point having two broker running on Homey

Well, honestly I don’t understand it. Some plugin is causing a conflict — something’s happening. Which one is it? I don’t know.

If you have the MQTT broker app installed, you should be able to configure the setting for it in their app settings page.
Once you know what settings it’s using, switch off the option to use the Homey built-in broker and enter the the port, username and password that is setup for the broker app. You can use the localhost for the url.
Then save the setting and restart the app. It should then connect to the MQTT broker app. Again you could send the log once you’ve done that if you want me to check it.
Obviously, you then need to ensure the presence sensor is configured with the correct details as well.
