I scanned the QR Code on the included card. It brought up instructions to allow me to add to the dashboard. The instructions then had me switch my phones wifi to be the hotspot for the sensor. That lost internet connection. The webpage on my phone put an overlay on top of the instructions which may it impossible to read.
I asked ChatGPT for help. It told me to use the browser and connect to the IP address of the sensor to finish setup.
To be honest, my first experience with this monitor is not good. This should have be an easy setup.
The address ChatGPT told me to use was: http://192.168.4.1
