Use a computer to connect to the wifi access point named Hoxton Direct hotspot.
After a few moments a Hoxton Direct popup should appear.
Use the dropdown menu to select the wifi network the sensor will ultimately sit on when installed.
Enter the wifi password.
After clicking the Connect button, you will be disconnected from the Hoxton Direct hotspot and be reconnected to the wifi network your computer was on before.
Wait up to one minute, during which the sensor will indicate a successful wifi connection with a solid red and green LED.
If the above steps do not work, please power cycle the sensor by removing power for 10 seconds, then reconnecting. Then retry the steps above. If still no progress see the Troubleshooting guide.
