Incorrect wind direction

Tempest just out of the box and mounted, but getting an incorrect/false wind direction. Only reading as from north, no matter which direction I turn the unit. Definitely blowing from the SSE during the entire time since it went online. Have tried the Direction Offset, and still no joy.

Also, when instructions say “point the arrow in the direction of north”, does that mean the printed arrow and logo is FACING north, or the opposite (facing south, pointing “up” as if north is straight ahead)?

@samwalkerobx The blue arrow must be facing towards the North direction. Once the Tempest is brought online it needs wind from all directions to settle in and the balance the sonic transducers. Give it some time to balance and if it doesn’t then have WeatherFlow take a look at your data to see if there is a possible hardware problem

To followup on KJ’s point. . .there are 4 Sonic Transducers underneath the “cap” or top of Tempest. With your back to the North, holding on to your Tempest and looking a the Blue arrow and Blue logo on the “back” of Tempest. . .there Must Be a Sonic Transducer directly Above that blue (North) arrow. The Transducers are arranged in a N / S E / W. configuration If you notice any one of them being slightly off. . .that is not exactly N-S E-W. . .then the unit probably will need to be exchanged.

Thanks, sounds like I need to practice a little patience. Appreciate the quick response.

If you have rotated it all the way around so it has seen wind from all directions it should be calibrated. It doesn’t take long. If you are only seeing wind from one direction submit a support ticket.

I have two weather stations, and the Tempest required a -25 degree offset entered into the settings to make it accurate. I will remove it from its mount later this week to ensure the sensors are all properly installed.

It took about 24 hours to calibrate, and it is now working properly. Thanks again for the input!

@samwalkerobx Good to hear the wind is working correctly.
