did you think about automating even the switching of the brightness? HA could do this based on the day-night cycle, dawn, etc. or it could also work with a room brightness detector
Hah, great question. I did. And then I realized, this only works if the TV is on the moment the switch happens.
Which in the evening is actually pretty commonly the case... But never in the morning.
oh right, because the TV is not available on the network when it's sleeping.
then you could save the desired brightness into some variable, and when the TV gets turned on apply the settings. I believe HA should be able to make an event when that happens. if there's a large delay, you could make a timer that forcibly refreshes the TV state every few seconds
Hmm, you mean when HA sees the TV come back? Interesting, that might work.
I's rather not do the force refresh option, because sometimes you do want different profiles. Very dark show, sometimes I want the bright setting at night. Very overcast day, sometimes the dark setting is better during the day.
