Snapshot and Restore functions in order to store and revert to a previous state (Sonos.snapshot equivalent) #356
Description
Snapshot function
This function should store all the parameters that the TV have in the current state.
Take a snapshot of what is currently playing on one or more TVs.
This action, and the following one, are useful if you want to play a doorbell or notification and then resume playback afterwards.
Restore function
Should be able to call the parameters stored by the snapshot function and put the TV back in that state.
The parameters should be able to restore the following, at least:
- Source (TV, HDMI1, HDMI2, App Plex/Netflix, etc)
- Channel used (if TV is source) or Movie/in case of Plex/Netflix
- Volume level
- Audio Out channel (Aux, HDMI soundboard)
- this list is not exhaustive, and could and should be continued to reflect the purpose of the function as needed
As a solution to be checked and analyzed in order to similarly implement:
sonos.snapshot and sonos.restore as implemented in the Sonos Integration
A functionality like this should allow using the TV for announcements, notifications and other short (or not) briefings with the certitude that we could get beck to the previous state of the TV.
