How to efficiently "flush" emulated hue?

Evening All,

I had an issue with my emulated_hue component and the fix was to:

1. Delete the emulated_hue_ids.json
2. Delete all the deviced on alexa.amazon.com

The above two steps have generally fixed the issue for me in the past. This time I had to do carry out a third step.

3. Stop the “offending” amazon devices.

Now my question is about the last point “Stop “offending” amazon devices.”. For some reason, although I deleted all the devices shown at alexa.amazon.com, some of the echo dots are still retaining the lights and sending requests to my pi.:

This was stopping the emualted_hue from working. I tried removing the devices and adding them again (as others have suggested in the cominuty) however this did not work for me. I ended up unplugging all the amazon devices and leaving one which I hopped wasn’t one of the *“offending” devices. I got lucky as when I rebooted the pi I didn’t get the above errors. I then scanned for devices and added all my lights again. A new emulated_hue_ids.json was created (the “offending” devices were stopping this from happenign it seems).

I’ve since plugged them back in and I am getting the errors again. The lights do work, however if my emulated_hue breaks again it would be nice to know how to properlly “flush” the amazon devices so I don’t have to go round unplugging all my dots & echos.
