KeyToUse was founded with a simple mission: to make smart home automation and industrial IoT solutions accessible and affordable for everyone. Whether you're a homeowner wanting to control lights and fans remotely, or a business owner managing multiple power sources, our products are designed to simplify your life.
Our core technology is built on Espressif's advanced chips – the same reliable hardware used in millions of IoT devices worldwide. This allows us to deliver high‑performance automation at a fraction of the cost of traditional systems. Every KeyToUse device undergoes rigorous testing to ensure durability and safety.
Every KeyToUse Core Module — and every product built with it — is rigorously tested for reliable performance and accuracy. Security is built in from the start, with encrypted communication that works smoothly even in multi‑user environments. Every action is logged with date and time for full transparency.
The module also supports up to six external sensors — three for "on" events, three for "off". This flexibility lets your product respond to real‑world conditions like temperature, motion, or water level — giving it an edge over standard smart devices in the market.
We're constantly innovating, and our upcoming iOS app and new product lines will bring even more convenience to our users.
Control all your KeyToUse devices from one intuitive mobile application. Available exclusively from our website.
Note: The app is only available for direct download from our website.
