True but to expect iro to support a photo cell is a bit much but supported by lots of automation systems for turning on lights at night. If you go,with a home automation system you could do things like I have done by hooking a motion sensor to turn,on,your landscape lights between the hours of 1 am to sunrise. Or engage geofencing to close your garage door when you leave. I also have my thermostat downstairs warm up at 5 am for my wife in the morning, plus turn on a few lights if and only if the outside temp is below 60 (I'm not onboard with nest quite yet).
These are things that the iro could never do for you, and shouldn't.
But I understand where you are coming from, I do, I'm just selfish and want more water saving features like flow sensors, well pump delays and some type of moisture sensor that is affordable and not a turd. Oh and HomeKit integration would be the bomb.
Now if rachio built a home,automation system, I would invest, all in...I like their style.
