“Child device with device network id C0A80015:0578 not found” is the message I get when trying to remove my Sonos from the web IDE.
It’s not being used in any smartapps.
Any help appreciated.
delete the network id for the device in the IDE and you should be able to delete the device in the IDE.
Genius! I changed the device ID to be 1111 and was able to delete it. Thank you.
