Hey @JazNz! The blue light flashing indicates it is in setup mode, and is a great start. I recommend plugging the chime in close to the router, and starting a new setup of the device in the app (Menu> Set Up a Device). With this being a new network, you’ll want to check things such as special characters in SSID or password. Check out this help center article for more connection tips.
If the above does not help to resolve your concern, our support team will be happy to troubleshoot further with you!
