AttributeError: 'H180Motor' object has no attribute 'serial'

We have H180 and whether it is connected or not we are getting:

I modified https://github.com/MITHaystack/srt-py/blob/master/srt/daemon/rotor_control/motors.py#L352 to:
Motor.__init__(self, port, az_limits=(-0.7,359), el_limits=(8.4,80), baudrate=2400),
and the error is gone. Also (89df766):
Motor.__init__(self, port, az_limits=az_limits, el_limits=el_limits, baudrate=baudrate),
is working. I got :

During handling of the above exception, another exception occurred:

Doing (esp8266/source-code-examples#26 (comment)):
sudo usermod -a -G tty,dialout $USER
fixed it and now its working.

FYI: I also get these warnings in a loop. This starts to show up when I launch the browser and SRT's Dash.

WARNING:waitress.queue:Task queue depth is 2
WARNING:waitress.queue:Task queue depth is 1
WARNING:waitress.queue:Task queue depth is 1

WARNING:waitress.queue:Task queue depth is 1

To fix this, maybe one more parameter should be added to the config file: DASHBOARD_THREADS by default set to at least 6 (I set 8 and the warning is gone in Firefox 123):

and passed to here:

I also got during env activation:

$ conda activate srtpy
WARNING: No ICDs were found. Either,
- Install a conda package providing a OpenCL implementation (pocl, oclgrind, intel-compute-runtime, beignet) or 
- Make your system-wide implementation visible by installing ocl-icd-system conda package.

From activated env I did:
conda install -c conda-forge ocl-icd-system
and the latter warning is gone.
EDIT: fixed in AlexKurek@3bbc50a
