Describe the bug
The treadmill Deerrun (PitPat-T01) is not working properly. The device turns on as soon as I start the QZ app but speed controls do not work. The treadmill just randomly beeps every few seconds, even without any interaction within the app.

To Reproduce
Steps to reproduce the behavior:

1. Go to 'main screen'
2. Click on '+' (multiple times) for speed
3. Speed does not change on the treadmill nor on the app

Expected behavior
The treadmill speed should be set to the same level as in the app
