I feel like this came up awhile back in the Android app discussion, and that it’s not an easy thing to add. I can’t find the specific posts.
You might be able to do this using Tasker, but I haven’t tried it.
- OH triggers a notification in the OH Android app
- Tasker sees/deletes the notification
- Tasker pushes its own notification with action buttons
- Pushing an action button sends a command to OH
It would be a lot of work, so I’d only want to do this for a handful of very specific actions.
