yes there is. thats what the app does for engaged or asleep state when specified in the settings.
yes you could do that. then create or the update the rule for engaged state to turn lights blue and dim them. use 60 secs for the power stays below so when the tv power is below the threshold for engaged for 60 seconds the room will move to checking then vacant.
if you do this whenever the room is set to engaged it will change the light color to blue and dim them. which works if you are only setting the room to engaged using the power plug for the tv. but if you also have contact sensor on the room door(s) and use those contact sensors to set also set the room to engaged it will also change the light color to blue and dim them.
not sure if this last part is OK for you?
if it is not … here is what i was thinking:
- adding power as an option to locked settings the same way it is an option for the engaged and asleep states.
- adding power range as a condition (not a trigger) to the rules. so when room is engaged and power is outside of a certain range you could use the while color for the lights. and if the room is engaged and power is inside of a certain range you could use the blue color and dim the lights.
i think the 2nd option is more flexible and will take care of broader range of use cases including yours.
will wait to hear from you.
