Find the right device for your home
Optimaatti supports multiple smart home ecosystems. Shelly devices connect directly, Tuya/Smart Life works via cloud, and Philips Hue connects through a local Bridge.
Supported smart home systems
Choose the ecosystem that suits you, or combine several.
Shelly
Direct WiFi connection without cloud service. Best suited for water heaters, heating, and large loads. Fastest response time and widest support in Optimaatti.
Best when you want a direct connection and precise control. Top choice for new users.
Tuya / Smart Life
Connect your existing smart devices to Optimaatti by signing in to your Tuya account. Thousands of devices from dozens of manufacturers: eMax, Nous, Woox, Moes and many more.
Best when you already have devices in the Tuya or Smart Life app.
Philips Hue
Local connection through the Hue Bridge. Control lights, plugs, and rooms automatically based on electricity price.
Best when you already have a Hue Bridge and Hue lights.
Zigbee
Zigbee devices connect through a separate coordinator device. Energy-efficient mesh network.
Best for experienced users who want to expand with Zigbee devices.
Matter
Next-generation standard for smart home device interoperability. Support in testing.
Coming later. The Matter standard is still in development.
