Rotary technology is a new way to power your home. It’s turn-key. Just wrap it in a shell, and you’re all done. The rotary technology is designed to provide the best power delivery in a compact system that’s lightweight, efficient, and easy to install. Rotary technology is an innovative solution for versatile home automation needs, utility, or tool systems. It can be used for everything from doorbells, to thermostats and even simple out doors with a single charge of the battery (as long as the system has an annual fuel usage of less than 160 pounds).
