Why does the Zaptec charger send blank ID tags?
If Authorisation required is turned off, the charging station doesn’t include an ID tag in its OCPP messages, resulting in a blank tag being sent to the 3rd-party OCPP server. Since most OCPP servers expect an ID tag for authentication, this can cause requests to fail unless the server handles empty tags.
How to fix it:
Enable Authorisation required to ensure a valid ID tag is always sent.
Or set a Default ID tag in the installation settings to replace the blank tag.
When using Authenticate through OCPP, keep Authorisation required enabled for reliable authentication.
