IEC104 / MQTT Gateway

MQTT Connection

Use a single + where the device MAC address appears in the topic.

IEC 104 Outstation

IEC 104 Connection Security

Comma-separated IPs and/or CIDR ranges. IEC 104 has no authentication of its own, so anyone who can reach this port can connect - leave blank to allow any source (not recommended once your master IPs are known). A connection from outside this list is dropped immediately, before any protocol exchange. Takes effect instantly, no restart.

Data Retention

Dashboard HTTP Port

Requires an application restart to take effect.
