Yes, ms_v_env_temp is already being used for that purpose.

That seems simple enough... except adding a new standard metric looks
like it would have implications for the protocol in ovms_server_v2.cpp.

OK, that's what I assumed for 'on', but I thought I'd better ask advice
given this comment in vehicle_nissanleaf.cpp:
// detecting that on is stale and therefor should turn off probably shouldn't
// be done like this
// perhaps there should be a car on-off state tracker and event generator in
// the core framework?
// perhaps interested code should be able to subscribe to "onChange" and
// "onStale" events for each metric?

OK, I have done that.

Yes, I am also familiar with Tom's work from the mynissanleaf.com forum.
I think he has mostly been working with a different model year, so it
will be interesting to compare the differences between the two.
