Why do I see rejected status when starting a remoteStartTransaction?

Following the OCPP specification, zappi will reject a remoteStartTransaction in the following scenarios:

1. A charging session is already on going 
2. The charger is in an unavailable or faulted state 

In some scenarios you may find that a remoteStartTransaction is incorrectly rejected. This can occur if the previous transaction did not close correctly. If your charger is incorrectly rejecting remore start transaction commands, please do the following:

1. Check that the criteria above has not been met 
2. Reset the charge point 
3. Once reset, confirm the charge point status is available or preparing (if a vehicle is plugged in)

Additional troubleshooting

If you continue to see rejected messages, it may be because a charging session is still open, please carry out the following:

1. Using the myenergi app or the buttons on zappi start a charging session by moving from STOP mode to one of the charge modes. A vehicle should be plugged in.
2. Allow charging to continue for around 2 minutes 
3. STOP the charging session using the myenergi app 
4. Wait for the stoptransaction message to be received on the OCPP platform you're using.
