I just got the GMC-500, it works great and is responsive, I have set up WiFi but I can't find the "Counter ID" and "User ID" numbers who gives them to me or where can I get them to find ? Thanks.
Go to https://www.gmcmap.com/manageDevice.asp and see your Geiger Counter ID which is your device ID. User ID is just the login name you use for this forum I think
