Had some fun playing with the Channels API. I came up with a simple HomeKit scene for my wife: say "Fixer Upper" and it:
- Uses ADB to turn on the TV with a Fire TV Stick,
- Reads the
upnextlist from the DVR, to find theIDof the next unwatched episode of her show, - Plays that recording
It's powered by the fixerupper Python3 script, below, and I use a homebridge plugin called cmdswitch2 for the HomeKit/Siri tie-in to a command. You need to turn on ADB Debugging on the FireStick, and generate an adb "key" (which I did with a python module called adb_shell and its keygen command ).
The only hitches: it takes some time for the TV to be powered up over ADB (~15sec or so), and by then the playback has started, but the Fire TV pauses it. So I monitor for a pause for 25 second, and use the API to resume if one is encountered.
Also, sometimes the Channels API goes down and is unreachable (Cannot connect to host 192.168.0.XX:57000). Restarting Channels on the Fire Stick manually resolves this. Possibly it was getting overwhelmed with too many requests during testing...
