Sorry, missed that part.
Correct, a rain sensor will help in micro-climates. Also, in the app we allow you to enable using personal weather stations. While these can provide much more localized data, be wary when opting in to use them. I’ve seen a lot of instances where the data is of bad quality.
In the next version of our app (2.0) we will allow you to choose a preferred weather station to use.
So, if you know and trust a nearby PWS, you can choose it ahead of time.
