Add a Sensor to Ctrl

In this section, we will explain how to add an SG Wireless sensor to Ctrl.

1. Navigate to Sensors and click on Add Sensor.

   

2. Enter the Sensor’s MAC address. You can enter just the last 3 segments.

3. Choose the device you want the sensor to be initially linked to.

4. Enter an appropriate Sensor Name and Sensor Description to better identify it.

   

5. The new sensor will appear on the Sensors page and in the linked device’s Sensor tab.

   

Each sensor can be linked to multiple devices, allowing for versatile integration. The data collected by the sensor will flow through the connected devices and ultimately reach Ctrl.

On your Dashboard, there should now be a Temperature and Humidity widget. These will update when the device sends sensor data to Ctrl. Multiple sensors will show up in a different colour with their name in the legend.
