Have you edited the action to “notify.notification_devices” for the forum? I would expect it to look like “notify.mobile_app_<your_device_id_here>”. If that’s what you’ve actually got, I’m guessing it’s a notify group rather than an Android companion app action. This is probably the problem - try putting just your phone’s notify action in there.
I think your YAML structure needs tweaking. For example, I believe the ttl and priority options need their own data: key. It can get complex with all these nested data: keys. You could try this, which mirrors a pattern that works for me::
- data:
message: >-
Bezoek aan de garagedeur om {{ now().strftime("%d/%-m/%-Y om
%H:%M:%S") }}
data:
data:
ttl: 0
priority: high
channel: alarm_stream
clickAction: /lovelace-mushroom/security-garagedoor
image: /local/tmp/snapshot-garagedeur.jpg
entity_id: camera.camera_garagedeur_substream
actions: ...
I’ve never used the channel option, so don’t know if that needs to move as well. I’ve also no experience of the clickAction and entity_id options, so you might need to experiment a bit.
This is a notification group? Does it have an iphone in the list? click_action, ttl, and priority are android specific keys and cannot be used in a text to an iphone.
