I’ve been having a heck of a time trying to get all of this down. While trying to run:
notify:
- name: savefile
platform: file
filename: file.txt
- alias: Device Discovered
trigger:
platform: event
event_type: device_tracker_new_device
action:
- service: notify.savefile
data_template:
message: '{{ trigger.event }}'
I get the error:
2017-05-18 21:47:27 ERROR (MainThread) [homeassistant.core] Error doing job: Task exception was never retrieved

Does anyone see anything weird about what I’m trying to do?
