feat(power): control TV screen

[khmm12]

It brings ability to directly turn off/on TV screen. Similar to "Settings -> Energy Saving -> Screen Off".

• Add missing permissions
• Add methods
• Add screen state property

Thanks, but this doesn't seem to work on LG Oled B8 with firmware 04.10.25, which model did you try it with? (I registered the client by deleting the existing .aiopylgtv.sqlite file.) To be clear:

• turn_screen_off : doesn't do anything
• if I put the screen to Off state manually under Energy Saving then any command will turn it on again, such as:
  • turn_screen_on , info_button, etc.

aiopylgtvcommand 192.168.1.78 turn_screen_off
None

Greetings @chros73 👋

I tested on C9 04.10.03.

turn_screen_off : doesn't do anything

Could you try with extra permissions? (e.g. from lgtv2)

WebOS also supports low-level method com.webos.service.tv.power/turnOffScreen, but it completely turns screen off, so TV doesn't change the power state and doesn't activate screen on remote actions.

If I put the screen to Off state manually under Energy Saving then any command will turn it on again

Which is expected, Webos leaves from Screen Off mode on any button/command with some exceptions like VolUp/VolDown.

The main problem is LG doesn't provide detailed documentation for their API 😞.

Does this work on a C8?
