Core: Owntracks: Unsupported message type (_lwt)

[tsvi]

Make sure you are running the latest version of Home Assistant before reporting an issue.

You should only file an issue if you found a bug. Feature and enhancement requests should go in the Feature Requests section of our community forum:

Home Assistant release (hass --version):
0.55.0

Python release (python3 --version):
3.5.3

Component/platform:
Owntracks

Description of problem:
I get error messages for an unsupported message type:_lwt and then a traceback NoneType object is not callable

Expected:
If decided to leave _lwt (last will and testament) message by owntracks unsupported, clean up the log so we don't get the traceback. Otherwise, support _lwt messages.

Problem-relevant configuration.yaml entries and steps to reproduce:

1. 
   
   
   2.
   
3.

Traceback (if applicable):

2017-10-08 07:54:27 WARNING (MainThread) [homeassistant.components.device_tracker.owntracks] Received unsupported message type: lwt.

Throwing in my two cents that I'm seeing this issue also. 👍🏻

This should really be fixed in OwnTracks. HTTP is stateless so there should be no will submitted

This is the regular owntracks (mqtt) not the http version.
