It works well even in the largest house.

So I had some issues setting this up on a poorly set up wifi network. Both 5ghz and 2.4ghz had the same ssid. And this only connects to 2.4 new firmware fixes the issues but I couldn't load it from the network I was setting it up on. customer service was amazing and offered to send me a new controller. I declined as I had a deadline to install this system. Took it home set up a network with the same ssid and password, did all the firmware updates. There where three. And dropped it right in. Set up all the sensors and have a happy customer. The sensors are super sensitive, I had it shut the water off several times during the install.
