"Sensor Unplugged" warning missing on app start w/ no sensor

[nilbus]

It did seem to work though after plugging and unplugging a sensor.

So still seeing this issue where Sensor Unplugged is missing. If I unplug and replug "hot" I get:

My derby_config.yml is:

admin_password: <%= ENV['DERBY_ADMIN_KEY'] %>
# device_glob: "/dev/tty{USB,.usbserial}*"
device_glob: "/dev/tty.usbserial"
lane_count: 3
sensor_class_name: MicroWizardFastTrack

Any ideas??

That "actor" that crashes is assigned to reading data from the USB serial device. ENXIO is an error that means the device is not there, which is expected but not handled directly, thus you see the error. After that actor crashes, it should remove that device and stop trying to talk to it. Then every 5 seconds, it continues to try to open the device again and start communicating with it. In other words, despite that error, I would expect it to continue to read times from the track sensor. Have you tried it afterward to see if it works?

I will investigate the separate issue of the "Sensor Unplugged" notice not showing.

I just pushed a fix for the sensor unplugged notification. Glad you pointed this out to me. Thanks!

I have tried afterward and still does not work. Tried following the plug sequence completely, unplug, wait 10 -20 seconds plugin again and get now response. It is like the code did not recover tho not sure what logs I should look at.
