Logitech harmony hub and Alexa

Sometimes the harmony hub does not turn off my projector 4K Sony vpl285es , happened twice and knew only the next day that projector was on, Does the projector goes into sleep mode or does this have a negative impact on projector life.

You may want to adjust the delays or the off command. Some projectors require you to hit Off twice in a row. Or they won't turn off between the projector syncs. Etc.

You might have to adjust those delays, or add in delays to make the power off command more reliable.

From my own experience with my harmony hub, if the harmony hub does not have a good wi-fi connection because it is too far from the router then it does not always work correctly. Do you know if this may possibly be an issue for you or do you get good wi-fi signal in the room your harmony hub is in?

Also, I'd advise you set a timeout on your projector of 3 or 4 hours (if you can), I think this will be long enough to be reasonable for the longest of movies and not interrupt your watching.

If it has timer events in the Harmony, you may also want to send a standard 'off' command for the projector which occurs at a specific time. Like at 3 AM or something like that. This way, if it is left on by mistake, it gets another chance for a power off command later on.

This, of course, is the power of more advanced control systems which offer 2-way communication via Ethernet or RS-232 control with logic.

Are you on?
Yes I am!
Well you are supposed to be off!
TURN OFF!!!
Okay.
Are you on?
Nope!
All is well.

^^ Delays are usually the problem in most of these programming-type automation projects. Control4, URC and more have the same issues.
