With the addition of binary sensors and alarm sensors, you may notice that some sensors are displaying new information. These new sensors work a bit differently than multilevel sensors because they do not clearly communicate what they are. So we set them up to allow users to configure them.
Initially, a binary sensor or alarm sensor will display the message "Setup required." To set up a binary sensor or alarm sensor:
Click on the Name of the device, then choose Edit.
A device that supports binary sensors or alarm sensors should have a category of the appropriate name in the list of edit options. You can configure what the sensor displays on the main page when it hasn't received any data yet, when it returns a true response, and when it returns a false response. You will need to select the sensor from the dropdown list, but you only need to fill out one of the three response fields.
For example, a motion sensor will display the true response when it detects motion.
