Sorry for the troubles. We have identified an issue with previously paired EcoLink Motion sensors that were missing specific information. If your Ecolink motion sensor stopped working following the update to version 2.1.5, please remove the cover of the sensor and while the cover is off, immediately go to your hub's web interface and then "Devices". Click on the link to your Ecolink Motion Sensor, then click "Configure".
If this doesn't solve the problem, you may need to exclude and re-include the device. If the issue persists, please send us an email at support@hubitat.com along with your device model (the model can be found on the back of your sensor) and a screenshot of your Device Detail page (including Data table).
