I do not like a timer system,
It comes on weather you are home or not, it wastes energy
a motion sensor does not waste energy, and you will have hw within 5 seconds

Or a system that constantly circs the water

I will stick with a low voltage motion sensor. it is more to my liking

the pump tied into the light switch of a bathroom works great if you are just doing 1 bathrom

Yes, and the other down side, you have to actually be aware of the schedule of the occupants, which may even require a conversation.

If the heating appliance is within 5 or 6' of the point of use, which renders a recirculating system unnecessary.

Whatever floats your boat.

What kind of water heater do you use? Instant or a tank?

I have a circulation pump on my hot water lines located in my master bathroom, the furthest point from the water heater. It has a timer. It also shuts itself off when the water reaches 95F. It uses the cold water line to send the water back towards the water heater. It has saved us a fair amount of water over the years, though I can't say how much. Before I installed it I could run 5 gallons of water out the tub before the water was hot enough to take a shower. I know it was 5 gallons because I ran it into a 5-gallon bucket and used it to flush the toilet. Now I run out about a gallon to get it to shower hot. The bigger water saver for us was going to front-loading clothes washer. That saved about 20% of our monthly usage. Having a 50-gallon gas water heater I really don't see an increase in gas costs from this setup. I mainly did it to cut down on the time it takes to get hot water for a shower.

If you have an instant water heater you want to use a setup like you're looking at. Constantly circulating the water would defeat the energy savings of a tankless water heater.

Lights and pump would share the same 120V, pump would be just another light.

Your system is working the same as the Lobster.
