There's not a lot of 3 zones transformers that also support control from the application, so I really wanted this DEWENWILS transformer as I have three zones for house spotlights: house facade, garage, and dormers on the roof. The original purchased transformer came with what appears to be a faulty zone three nbsp;the lights would just blink but would not stay on. The service was quick and efficient: the company sent me a replacement which worked perfectly. Now I have independent schedules for different zones, and can control it from my iPhone. (Thank you, Mia, you were great!).

Box is well constructed and fully capable of handling my style and number of lights. To get it connected to wifi, had to connect and program on older router with dedicated 2.5 band. Connection was then easy. Lacking considerably for programming via the cell phone. The app doesn't work as expected. After setting a time to turn on, doesn't work. The setting for turning off, has worked most of the time. Additional programming for the app would definitely help.

I replaced a 15 year-old 300W, 3 zone transformer with this one. I have it installed on the interior wall of my garage where the old one was. The new one is half the size, very quiet when running, and took about 10 minutes to connect and set up with the app. This does not support an optical light sensor (for dusk to dawn operations), but with the Wi-Fi connectivity and the app, you can set a schedule relative to sunrise and sunset. It seems to be well made. Assuming it lasts, this will be a great purchase.

Pretty much everything in our house is smart so I was excited to be able to upgrade our landscape lights using this wifi landscape transformer. I had an existing 300 watt transformer with a photo sensor on it so my lights would turn on at dusk and turn off at dawn. What's nice about this WiFi transformer is that you can utilize three separate zones and control them at will or program them based on your needs.
