Recommended lock settings for OCPP

If you're using your zappi in a public place you might want to restrict access to your zappi so it can only be used by authenticated users. zappi, using OCPP, achieves this by moving zappi from STOP to one of the charging modes such as FAST after a user successfully authenticates and back again after the charging session has completed. 

To do this you'll need to configure the lock function on zappi. This will:

1. Only allow charging by authorized users 
2. Prevent the adjustment of device settings 

Important: zappi settings can still be accessed at the device by using the 5 digit PIN code. It's important you change the PIN code on the device from the default to prevent unauthorised access. You can also disable PIN code unlock and only allow remote unlocking of the PIN lock, when zappi has access to a communications network, in the OCPP Configuration.
