Easy to install. Wi-Fi connected over a long distance. The app is excellent. The downside is the operating temperature range, which isn't listed on Revain. From -14Β°C to +60Β°C. Converts this 14F to 140F. I was hoping to use it to control my Dock Defroster. As soon as the temperature dropped to almost zero, the device switched itself off. I'm praying the unit is still powering the defroster as I'm not around to check and it's record cold. 14F as the low operating range is too high for outdoor use in the Midwest. If they can improve on this (let's say 30F below) this device will be amazing. I was able to program it to turn on at 32F AND wind speeds less than 1 mph (it takes the wind speed from a local weather forecast on the internet). All kinds of parameters can be programmed for a variety of devices. Easy to use and powerful application. It even let me know that the device was shutting down with a warning and a message. However, with a limited range of outdoor operating temperatures, it will not be effective for my needs.
