I want to revive this because it's still very hit-and-miss for me. It rains infrequently in San Diego, so it's often a long time between instances where my rain sensor activates. The last time my 'rain sensor activated' rule triggered properly was on Nov 21, but I got a notification from my Rachio v2 last night that rain sensor had activated (correctly), but the recipe didn't run. I manually checked it, but it still didn't trigger. I had to manually set up a rain delay.
It's frustrating because I have no obvious way to debug it. All I can do is look at the IFTTT history and see that it didn't trigger in response to the registered Rachio event. Is there any way to figure out what's going on? Should I at least be able to successfully manually check the rule when the rain sensor is activated and have the rule run? It's just not working for me.
