How do I fix the Pollen platform after upgrading to .82?

Configuration
1

I see in the release notes that the Pollen platform has a breaking change, tried updating numpy with sudo pip install numpy --upgrade and it appeared to work but still getting the following in my log

@bachya Can you please explain how I get all the sensors back. I’m currently only getting the index sensors. The average sensors are not being returned. Thanks

I’m not sure what’s happened. You shouldn’t have to update numpy manually – your excretions point to an issue there.

Thanks for getting back to me. I wasn’t clear in describing the problem. I have successfully been using the pollen platform on release 81.1.6 As soon as I updated to 82 I started getting the errors in my log that I posted.

After I read thru the release notes again I got the idea that I needed to do something in order to correct the problem, hence the numpy upgrade. But that didn’t work either.

The release notes state a breaking change, am I suppose to do something different in Home Assistant 82 that I didn’t have in 81.1.6?

Thanks

If you take a look at the PR that made the change, it says

Breaking Change: Because of the longer statistical view, trend attributes will no longer return a value of “Flat”. All automations relying on that value will need to be updated.

So on my reading, only automations need to change, not the component itself.

Thanks to post Problem after upgrading to 0.62 @andreas.w my Pollen problem has been solved
