1. you can try getting the two pipes of the U-piece leveled by having them bent - may need special tools
2. put some material between the U-end where the WS80 sits and the first (top) bracket holding the WS80 pipe so it will compensate the tilt and become vertical.

The optical sensor will be added in parallel with the current WS90, providing more rain status data. It does not replace the current WS90 design; it is just an extra add-on that might help improve the sensor for low or high rain rate conditions.
It is always worth trying something different. Since this is just an idea, there is no guaranteed good result. It is just a keep-and-trying method. It won't worsen it, but I don't know how good it will be.

Very good- this is just what I thought - and it shows the creative and innovative approach at Ecowitt 
one also has to be ready to fail - at least at the first steps - but without leaving trotten paths no or very little innovation is possible

Weird all my other apps show on my phone under settings except for the weatherlink app.
I deleted the app and reinstalled it and the wind section now shows in the app but doesn’t display any data for wind.
Not sure if something is going on with the app itself or a setting im missing

I just set up the anny with a separate wireless transmitter and the 6313 console. I am setting up the rest of the sensor suite at a later time after some construction around the house is done. I needed to setup the anny on top of the roof prior to everything.
I also have the weatherlink app on my phone.
The anny works properly and the wireless transmitter is sending data to the console just fine on a different channel than what the sensor suite is set up for. The console is also displaying the indoor temp, humidity, and barometric pressure just fine.
Here is the issue:
On the weatherlink app it displays the temp, humidity and pressure as is displayed on the console but the wind is not displaying on the app.
Also when i go into the settings it asks if i want to upgrade from “station tier basic” for $47. I am subscribed to the pro after paying the $47 when i set up the Weatherlink account on my phone. It also shows on my console my subscription is “pro”.
Is the wind not showing on the app have anything to do with the subscription and why is the pro not showing on the app but is in the console.
Am i missing something or setting something wrong?
Thanks
