+Cloud Execution
+
+Works with: 
+
+* [Ecolink PIR Motion Detector with Pet Immunity](https://www.smartthings.com/works-with-smartthings/sensors/ecolink-pir-motion-detector-with-pet-immunity)

+* [Capabilities](#capabilities)
+* [Health](#device-health)
+* [Battery](#battery-specification)
+* [Troubleshooting](#troubleshooting)
+
+## Capabilities
+
+* **Motion Sensor** - can detect motion
+* **Sensor** - detects sensor events
+* **Battery** - defines device uses a battery
+* **Health Check** - indicates ability to get device health notifications
+
+## Device Health
+
+Ecolink PIR Motion Detector with Pet Immunity is a Z-wave sleepy device and wakes up every 4 hours.
+Device-Watch allows 2 check-in misses from device plus some lag time. So Check-in interval = (2*4*60 + 2)mins = 482 mins.
+
+* __482min__ checkInterval
+
+## Battery Specification
+
+One CR123A Lithium 3V battery is required.
+
+## Troubleshooting
+
+If the device doesn't pair when trying from the SmartThings mobile app, it is possible that the device is out of range.
+Pairing needs to be tried again by placing the device closer to the hub.
+Instructions related to pairing, resetting and removing the device from SmartThings can be found in the following link:
