Hi,
Terminology...
You are talking about the Weatherlink App and I was presuming the Weatherlink.com site as per your subject line!
On the Weatherlink App I checked yours and mine. Need to keep in mind that my station and Weatherlink.com settings are in Celsius so if I look at another site on Weatherlink.com or Weatherlink App, like yours that uploads in Fahrenheit, it shows up for me converted to Celsius. When checking it,
Your Station screen shows Temp 34.2°C and Feels like 40.5°C
My Station screen (WiFiLogger/basic WL.com) shows Temp 24.6°C and Feels like 24.7°C
My Station screen (Weatherlink Live/Pro WL.com) shows Temp 25.1°C and Feels like 25.1°C
Your Station Tier screen: Basic shows Temp 34.3°C and Feels like 42.3°C
My Station Tier screen: Basic shows Temp 24.6°C and Feels like 23.8°C
My Station Tier screen: (Weatherlink Live/Pro WL.com) shows Temp 24.6 and Feels like 24.8°C
There is some difference due to time when checking but not significant.
But when I check Temp and Feels like in my CumulusMX there is often a 2 to 3°C or more difference. I believe it is because of wind at the time as that will have a great impact on the feels like! CumulusMX updates wind more frequently than WL.com.
Enjoy,
Paul
