Hi all,
It looks like I accidentally removed a device from the app (Aqara double rocker remote switch). Suddenly I noticed a little red mark in my automation lists. I thought I remembered that somewhere in the app there was an option to place deleted stuff back? Am I tripping, or is there such an option?
@teun487 Hello!
No worries, you’re not tripping! There is indeed a way to get your deleted devices back. When a device is accidentally deleted, you can re-add it to the original family, and the basic information, automations, and scenes of the device will be automatically restored. The red exclamation mark in your automation list indicates that there are devices offline or deleted within this automation, which is likely due to your removed device.
If you find that devices are frequently deleted by mistake, it might be helpful to enable the anti-mistaken deletion function. This can help prevent accidental removals in the future.
Feel free to try re-adding the device and let us know how it goes, or if you have any further questions! 
Hello @teun487
If you have deleted the device, you can only return it by adding it again to the application, put the device into pairing mode as indicated in the instructions for the device and in the application, click add device and. go through all the steps and it will be added.
