Hi Patrick,

You need to be using the external IP address in order to access the OpenSprinkler outside of the WiFi network (eg: cell network). The other caveat is the OpenSprinkler port must be port forwarded through your router.

The external IP can be found at or typing ‘ip’ into Google.

To port forward your OpenSprinkler, you will need to identify your router model and consult it’s documentation for opening a port. The default port is 80. Some guides are available here: If you need assistance let us know.
