Support for Philips 55PUS8108/12 (API 6.1.0) - Entity unavailable when off & Toggle issues

[Bjoern3D]

Describe the bug
I am trying to set up the integration with my Philips TV (Model 55PUS8108/12). I suspect this is related to Issue #6 regarding newer API versions (API 6.1.0).

I have successfully retrieved the Username and Password using the philips_android_tv script and configured the integration using the HTTPS protocol.

I am experiencing two main issues:

1. Availability: When the Ambilight is active, the entity shows as on. However, when the state is off, the entity becomes unavailable in Home Assistant.
2. Control: Changing Ambilight modes works fine. However, turning the Ambilight OFF via Home Assistant does not work correctly. The switch in HA immediately jumps back to on.
   • Observation: Interestingly, if I check the Ambilight menu on the TV with the remote afterwards, it shows as "OFF", but the command seems to be stuck or not fully confirmed via the API.

System Health

• Integration Version: 0.2.12
• Home Assistant Core: 2026.1.3
• Home Assistant OS: 17.0
• Supervisor: 2026.01.1

Additional Context

• I used the python script from suborb/philips_android_tv https://github.com/suborb/philips_android_tv/tree/master to obtain credentials.
• The pairing type reported by the TV is digest_auth_pairing.
• secured_transport is true.

Any help or guidance on how to support this API version would be appreciated.

Device Information
The TV is a 55PUS8108/12 running on Linux (likely Titan OS/Saphi, not standard Android TV).
Here is the system output from http://<ip>:1925/system:

Addendum: Error on HA Restart / Startup

I noticed another critical behavior related to the "unavailable" state.
If the TV/Ambilight is OFF and Home Assistant restarts, the integration fails to initialize entirely with a Config entry not ready error.

The log confirms a JSONDecodeError. It seems that when the TV is in standby, the API returns an empty body or invalid data instead of a JSON response, causing response.json() to crash the setup process.
