[ENG] 15.4. [DKSF 48.5 IU] The Control of the 1-wire Smoke Sensors

The interface of URL-encoded commands in the device can be used to integrate with web applications without using the SNMP protocol. Through the interface of URL-encoded commands, control of 1-wire smoke detectors is available.

Request about the relay state


N — the number of the smoke sensor.

Return values

Error in the request (wrong format, wrong number of sensor)

To add a login and password to the structure of a URL-encoded command, it is possible to use the next scheme:

  • http://<username>:<password>@<host>:<port>/<URL‐path>?<parameters>


<username>:<password> – are credentials for authorization in a device web interface;

<host>  is an IP address of a device;

<port>  is a port of an HTTP server;

<URL‐path>?<parameters>  is a URL-encoded command
