Device tracker not working in 28.2

Configuration
1

After I upgraded to 0.28.2 My device tracker seems to not be working anymore. The log posts the following error:

16-09-22 23:17:04 homeassistant.bootstrap: Error during setup of component device_tracker
Traceback (most recent call last):

Basic rebooting and reinstalling the update doesnt seem to fix the issue and I’m not sure where to go from here.

Has anyone else experienced this?

You’ve cut off the error which is either in the few lines above or below your log.

My bad, try this one:

It seems that your known_devices.yaml is not valid. By any chance, do you have a line that ends with a semicolon in there. Like hello: ?

I’ve added a pivotal story to generate a better error in the future :thumbsup:

I think the same thing happened to me after a recent update (probably 0.28). The issue was caused by a new known device which had square brackets in its name. I fixed it by putting double quotes around the name (something I always do, no matter the entity).

Thank you both for your advice!

So it appears that a new device (Apple Watch… I always figured they had some sort of wifi in them) did cause the issue because it was only defined, but non of the entities were listed or populated.

I added the MAC address, the name, and visibility and tracking options and rebooted the server. That seemed to have worked well, although it took a really long time for HA to start back up. the log file now lists this:

So keeping an eye on this it seems as if iCloud is the only device tracking system as it doesn’t seem to want to load NMAP (see the error above). I’ve tried reinstalling NMAP on the Mac but that doesn’t seem to solve the issue.
