HTTP-based Device Connection¶

EnOS Cloud provides a device side SDK for HTTP protocol-based device-side development.

If the provided HTTP SDK cannot meet your needs, you can develop a custom device-side SDK according to EnOS device protocol provided for you in this section to establish an HTTP-protocol-based data transfer channel between the device and EnOS.

HTTP Ports¶

Domain	Port	Protocol	Notes
iot-http-{env}	443	HTTPS
iot-http-{env}	8080	HTTP	It is recommended to use this when the security requirement is relatively low.

Where, “{env}” is the domain name of the EnOS environment. For example, if your logged-in EnOS domain is “app-portal-cn5.envisioniot.com”, the domain name will be “iot-http-cn5.envisioniot.com”.
