1. A 2.4 GHz Wi-Fi network
KB panels join 2.4 GHz Wi-Fi. Most home routers broadcast both 2.4 GHz and 5 GHz. If yours combines them under one name, you may need a separate 2.4 GHz name while pairing.
2. The Smart Life app
Install Smart Life from the App Store or Google Play, create an account, and add each panel. Give every switch a clear name such as "Bedroom light" or "Hall fan", because these are the names you will say to Alexa or Google.
3. Link Alexa or Google Home
In the Alexa app, enable the Smart Life skill and sign in with your Smart Life account. In the Google Home app, add a device, choose "Works with Google", pick Smart Life and sign in. Your switches then appear in the assistant's app.
Without the internet
If the Wi-Fi goes down, KB panels still work by touch. Only the app and voice control wait for the connection to return.
