ZigBee Gateway API: Server API and Gateway API for SEG-X3 and SEG-X5

Short answer: The OWON SEG-X3 and SEG-X5 gateways offer an open Server API and Gateway API so a third-party cloud server or mobile app can control and monitor the ZigBee devices on the gateway. Commands and messages use JSON over TCP/IP, TCP or UDP.

What integration interfaces exist?

The SEG-X5 datasheet shows three interfaces between the gateway and third-party systems: an app API, a Server API and a Gateway API. Third parties can connect their own cloud server, PC dashboard or mobile app to the OWON gateway and the surrounding energy, HVAC, sensor, lighting and care devices.

How do ZigBee devices join the gateway?

Set the gateway to permit joining, then power on or reset the ZigBee device. The device joins the gateway's network automatically, as described in the OWON device quick start guides.

What about the SEG-X6?

The SEG-X6 quick start guide describes a ZigBee 3.0 gateway with 4G LTE Cat1 but does not list an API.
