Where can I get the most current firmware?
The kit I just received has FW version 4.8.0 and the session KWh doesn't reset between charge. I see that it may be corrected with a later than 4.8.0 version but the official repository (open_evse) in GitHub has only 4.8.0.
The most current tested release is 4.8.0. If you would like to run the development code you can download, compile and load from https://github.com/lincomatic/open_evse.
the session kwh (left) should reset and add to the total (right) as soon as you unplug the vehicle.
The standard 4.8.0 release should work fine. After the session, unplug the EV. The session is added to the total, the next time you connect is should start at 0.
Development code is not pre-compiled. Periodically we compile, test and release. 4.8.0 is the latest.
I suspect I have the same issue as Francois but have been too lazy to report it.
The session kWh does not reset if you use the timer function. In my case I have it set to start at 11:00pm and finish at 07:00am. When I'm using the timer the session kWh does not reset. Interestingly the elapsed time does reset, there must be some difference in how each item is reset.
If I don't use the timer the session kWh resets each time.
