Automations stopped working after Autostart setup

I’ve got a strange problem, I’m using PC with Ubuntu 16.04 and the Python 2.7.12 virtual environment for HASS 0.63.3 as here.

I’ve been manually starting HA in the past with:

sudo su -s /bin/bash homeassistant
source /srv/homeassistant/bin/activate
hass

Yesterday I setup Autostart using systemd from here and followed this to the letter with no issues. Now, the majority of things are still working as before, but several of my automations seem to have stopped working.
These were all working a couple of days ago and nothing else has changed… Both the below components load on startup… can’t see any errors… anyone with any ideas??
Thanks in advance…

The Doorbird event does not seem to happen when the button it pushed:

- alias: Doorbird ring
  trigger:
  - platform: event
    event_type: doorbird_doorbell

The lights no longer turn on when Plex is paused…

- alias: "Lounge Room Media player paused"
  trigger:
    - platform: state
      entity_id: media_player.tv_ua65js8000
      from: 'playing'
      to: 'paused'
  condition:
    - condition: state
      entity_id: sun.sun
      state: 'below_horizon'
  action:
      service: light.turn_on
      data:
        entity_id: light.tv_4
        data:
          brightness_pct: 20

Have you had any progress with this ? I noticed this evening that Plex is no longer changing states.
At least I thought wasn’t…
I went to watch a movie and the lamp didn’t turn off. Not being bothered to look into it straight away I just turned the lamp off manually.
When I paused the movie and the lamp came on I thought it must have just been a strange glitch, but then the light didn’t turn off when playing again so I’m not really sure what’s going on.
I haven’t noticed any issues with other automations.

Nah, the problem seems to happen when HA auto starts on boot. Now I stop it after boot and restart manually - not idea what’s going on…

Bugger ! Mine was slot simpler, I just restarted Rasplex and everything is working as per normal

Long shot but are you sure your automations are switched ‘on’ in the states menu? On occasion mine switch themselves off.
