Set up WD to use WeatherFlow - Temp reads ok for about 5 min then 12.4F lower

VERY odd - I set up a trial version of weather Display yesterday to connect to the WeatherFlow. All was well for about 5 minutes, then the outside temp from the Air module suddenly started ready 12.4 deg F LOWER than the actual Air outside temp as shown on the iPhone connected to the station. Air batteries are brand new Li as recommended at 3.552V, and WD is reading wind correctly. The barometer and humidity are also displayed much lower than on the iOS console.

What have I done wrong here?

HI
email or PM me your station ID and I will test here

I MIGHT have stumbled on a solution ---- I logged on to my router and selected Bind MAC/IP in the wifi device list for the WeatherFlow Hub. As soon as the WiFi router restarted, the data came into WD as it was supposed to. When the hub was just set on the router for plain DHCP, it was getting an IP address each time it tried to upload. I watched the router page as it connected and disconnected. Now it seems for the past 30 minutes anyway, that it keeps the same IP address and WD is happy once again.
