When I first started setting up my Rachio 3, I noticed the broken Weather Intelligence Plus calendar and weather station errors in the web interface and it massively reduced my confidence in the system as a whole.
Seems odd that Rachio would continue to publish a web interface that is broken and no longer supported. Why do it? For a new user like me, it causes a lot of unnecessary angst during the initial learning curve / setup process, and for the company it gives a really lousy impression.
Rachio should take down the web interface, or update / fix it. If not, then at the very least, post a warning message on the landing page informing people that the page is broken and not to use it,
