I'm looking for a way to limit my charging (time) at home so I'm looking for a timer/control.

 I've been using a regular mechanical timer (https://www.amazon.com/gp/product/B00435KOUY/ref=oh_aui_search_detailpage?ie=UTF8&psc=1 ) which is pretty economical and has been working fine for over a year now,
...........

Have you checked the temperature of the connections after several hours of use?

I find that the connections on the 10' 14/3 cord get significantly warm so I'm hesitant to add more connections thus looking for a controllable socket.
There out there but all seem to be part of a compleat system (vs stand alone).

I have to think Zero will eventually have to include delayed/metered charging to its system. 
It's too important to many customers not to provide it & to me the Laymen, it doesn't seam that difficult/expensive to do.

Yes, and heat has not been a problem at all. I have a 25-foot 14AWG power cable that I got from monoprice (https://www.monoprice.com/product?c_id=102&cp_id=10228&cs_id=1022801&p_id=5279&seq=1&format=2 ), and 14 AWG is rated for 15A continuous even in a conduit, so it's certainly adequate for a free-air application like this.

But you're right, if there's going to be a problem with heat generation, it's going to be at the connectors. So I regularly check to make sure things aren't getting corroded, and the outlet sockets aren't "sprung" so there's not enough tension to ensure good contact. I also like to bend the prongs inward just slightly on the male plug, again just to make sure there's tension between the mating parts of the connection. On my setup, nothing even gets warm.

I forgot about monoprice when I ordered my power cords from Amazon.
Probably paid 2-3 times more (but at least shipping was free).

... looking for a controllable socket. ...


I looked at the Wemo Insight automatic standby, which doesn't work (99 watts is the limit) but it looks like you may be able to program it.

If you know Python, this looks promising:

The Wemo Insight has a current_power() method:

http://ouimeaux.readthedocs.io/en/latest/_modules/ouimeaux/device/insight.html

I'm thinking to monitor as follows:

every 5 minutes:
  if charging load detected on switch feeding the zero, record load
  if load 5 minutes ago is greater than current load, and current load < 500w, turn switch off

obviously all numbers tunable, and maybe there will be a need to do a rolling average, but it ought to work

It's like flying, but with more traction.  And none of that Z-axis complexity.

Lost my faith in Zero with my 2011 S, but regained it with my 2014 SR.  Diginow SCv2 changed my SR from a fun ride to primary transport.
