Guardian Valve Controllers require an active internet connection transmitted over a 2.4 GHz band for installation on the app. Although many modern routers do transmit both 2.4 and 5 GHz bands, your valve controller will only pick up the appropriate 2.4 GHz band channels when you view available connections through our Guardian app.
However, once your devices have already been set up on the app, if you do have an internet outage, the Valve Controller will still close your valve in the event of a leak.
Please note that in order to monitor your system status using the app, remotely control your valve, and receive notifications, you will need your phone to be connected to the internet.
