Characteristic Properties

Use the following JSON in your characteristic properties so that the Home application displays a smoke sensor with status tampered.

{
  "SmokeDetected": 0,
  "StatusTampered": false
}

Example

Implementation with an Omron PLC

This is an example of a smoke sensor element wired in NC with a safety if the sensor is open.

Smoke Sensor Omron PLC

In this example our PLC address is CIO10
