Netatmo automation - 'device' triggered through UI doesn't work, 'event' triggered does

Upgrading /restarting my home automation with Fibaro HC3 and considering how much I will use HA at this point…so far my HA green is opening a lot of doors I never thought possible.

I am currently being distracted trying to use my netatmo cameras as motion sensors. Everything is working, network-wise (though I want to keep trying to get it working without relying on Nabucasa), but I have been having difficulty getting a scene to work.

I first tried using the UI config, and ended up with the following trigger from “Camera detected a human” (shown as YAML for comparability):

device_id: 794373375f7cb4336b62255331227eb5
domain: netatmo
entity_id: e1cb89771a80fac50848baabef4742c1
type: human
trigger: device

This doesn’t work. I’ve tried a few other permutations like ‘outdoor event’ also without success.

So I tried listening for events and eventually got this trigger working:

event_type: netatmo_event
event_data:
  type: human
  data:
    event_type: human
    camera_id: re:da:ct:ed:mc
trigger: event

I certainly could go ahead using the event based method, but I’d prefer to be able to rely on the UI where possible.

Any hints? Might this be a bug in the integration?
