About 25% of the time - when I try to go into the rachio app on my phone - it shows the controller as offline. About 50-75% of the time when I try to turn on (or end early) a quick run - it is extremely unresponsive (even though online). For instance, I was recently replacing a lot of my sprinkler heads. I would test out my different zones here and there… 1/2 the time, the zone wouldn’t start - and at least 1/2 the time, when I wanted to end that run early (pressing the stop button) - it would take 20-30 seconds to respond (if it responded). So the latency in the unit responding to commands is extremely bad.
I already have an investment in this - so I am not going anywhere - but at this point, if I had to replace it - I certainly would try another brand.
