@sumo try searching on pwsweather (link) and here is a writeup about how to look for a good station on weather underground (link).
I use a cheap Acurite 5-in-1 station. There is a good way to accurately calibrate them for rain, which is the most important parameter that Rachio requires. Netatmo will work as well, but it’s more expensive and harder to accurately calibrate.
