I am trying to setup my smart home to use motion sensor to

I am trying to setup my smart home to use motion sensor to turn on and off led lights throughout my house. I need to decide how long it should wait without detecting motion to turn off the lights. I am afraid that setting it for too short duration like "5 minutes" will put too much wear and tear to the switch and not really save energy because LED are so efficient that the act of switching them on and off could take more energy than had they been lit for 15 minutes rather than being lit for 5 minutes ....unlit for 5 minutes ...and lit again for 5 minutes ?I think I was told that turning the PC and and off is more wasteful than just letting it turned on, and they may have told me about about over appliances too.Personally even if I don't save energy I like to keep lit only when needed as long as I don't waste energy either by the act of the switch going on and off, or put too much wear and tear on the switch. Of course I don't actually touch it, but there is still some mechanism going on and off in the switch and if that's triggered for 10,000 a year vs 1,000 times a year it still matters no ?

I'm in the process of replacing a switch with a 600 W dimmer

Hi! I'm in the process of replacing a switch with a 600 W dimmer in the bathroom. Single pole. The original switch operated two lights - a recessed heat lamp light, and a vanity light. Total of about 400 watts in the room. I thought I reconnected everything correctly but clearly didn't because now only the heat light works.JA: I'll do all I can to help. How long have you been dealing with this?Customer: A day. :)JA: Do you plan on doing the work yourself?Customer: Yes.JA: Anything else we should know to help you best?Customer: I think I explained everything. As least that I'm aware of. I also replace the fan switch in the same box and its working fine.

When I open my refrigerator doors or the dishwasher cycles the over head high hats lights dim. When I removed the high hat switchs and put a regular switch the high hats didn't dim. What could cause the dimming if the switchs are not defective?

We have 6 recessed lights in a room. I can only install 5 because the 6th will always burn out. Even the very moment I install the bulb, it burns out. Thanks.
