Tempest Integration with Rachio

What is the benefit of paying for an integration code from Rachio for my Tempest vs just linking my station to WeatherUnderground and choosing it as a PWS in the Rachio app?

I didn’t know that was the case also until I tried the integration. Not worth it. Glad I could use weather underground and get my station without the fee. Can’t wait to get the monsoons and see how it works.
