I spent about an hour and a half trying to get the this app weather station to connect to WiFi. To make things easier, do create a account with wunderground. After an account is created, then add your device to get a station ID and Key. Do copy the credentials.
One time I did get a WiFi connection with my iPhone but no internet connection. I tried everything and Sainlogic instructions get confusing. I tried maybe five times. iPhone 11, iOS 16.1.2. Sainlogic may not be up to date with recent iOS updates that may prevented WiFi connection.
Reading the three setup guides and manuals, it finally worked when using my laptop to connect the console to the WiFi On the laptop, connect to the weather station on the WiFi list, type in http://192.165.5.1. Then fill in the information. Once entered the weather station connected. On Sainlogic need to add the device using the device credentials info from wunderground, all things worked.
