So I'm back to an old problem of mine, the recirc pump on the hot water.
The wife insists that the pump be on all the time but it is pretty wasteful of energy. We have solar hot water but on a cloudy day or in the winter, the backup has to come on.
I have the pump as an output on Elk M1 Gold. I need to use a motion detector in the bedroom to activate the pump in the morning. I usually shut it off manually at night or it shuts off at 11pm.
What I'd like is for it to shut off when she is out of the house. Lots of ways to do that but it needs to be on for 5+ minutes before she gets home. What I would love to do is shut the pump off when she leaves the house and then turn on when she is 2 miles from the house (ie returning home). She carries a droid and I can get her to keep GPS on if needed.
The other thing I'd like is a low circ mode - like run the pump 2 minutes every 15 when someone less sensitive is at the house (think babysitter) to give reasonably hot water most of the time but not 120+degrees within 5 secs from every tap like my wife wants.
I'm thinking a software HA add on to the ELK could do this but which one?
There are probably other more sinister uses of geofencing the wife but I assure you mine is pretty clean.....
