problem with delayed charging and lifetime cumulative energy

I hope this is the right place for this.
I recently installed an openEVSE (current firmware) and I have a
few questions / problems.
1) Delayed charging is not working for me.I drive a Think, which is older and does not
fully support the current version of J1772 (for example, it will not stop
charging when you push the trigger on the gun). But
I tested delayed charging at a friend's house on his openEVSE (older
firmware) and it worked.When I set
delayed charging on my unit, the EVSE closes the contactor at the set time, but
the car does not charge.Oddly, the wh
do begin counting up very slowly, but the current shows 0amps.I think it may be charging the 12V through
the DC-DC converter?But the traction
battery does not charge.Any idea what
to look at?
2) What is sleep mode?Whenever I am not charging, and I push the button one time, the EVSE
switches to a pink screen and says "sleeping".Is there any significance to it?It sounds like it is waiting for something,
but I don't see any way to stop sleeping.
3) The lifetime cumulative energy (wh consumed) is way
off.After a charging session, I will
note the wh consumed for that session and then push the button to open the
contactor.Then after disconnecting and
going back to the ready screen, the lifetime total increments by the amount
used during that session.But each time
I toggle between sleep mode and ready mode, the lifetime total increments
again.This is not a huge deal, but I
don't think it's supposed to work that way.
