Alex,
You can PM me few email accounts that you might have used and I’ll reply to the address that matches the existing account.
Alternatively you can put your Garadget into listening mode, connect any smartphone/computer to its PHOTON-XXXX hot spot and go to http://192.168.0.1/device-id in the browser. That will give you the device ID which I can use to lookup the account that owns it. Again, for security reasons I’ll only give the info to the email address on that account.
