Definitely! The G1 WiFi Gateway's Ethernet jack is an alternative way to connect to your network instead of using WiFi.
If you have already set up the gateway in the SensorPush app, just plug an Ethernet cable from the gateway into an open port on your router or network switch. The gateway will start communicating with the SensorPush Cloud automatically. You don't need to set it up again.
If you have not yet set up your gateway, add it in the SensorPush app as usual (this links it to your account). When you reach the step where you choose a WiFi network, plug in the Ethernet cable instead and wait for the "Connected via Ethernet" message to appear. Then you can finish setup.
A few things to know:
- Your network must assign addresses automatically (DHCP). Static IP addresses aren't supported.
- Web-based sign-in pages (like you often see in hotels) aren't supported, whether you use Ethernet or WiFi.
- If your network has a firewall, see What ports do I need to open for the Gateway?
Ethernet is also a good fallback if your gateway won't connect to your WiFi network. See My Gateway won't connect to WiFi.
