Secure with end to end encryption

In environments where the local Wi-Fi network cannot be secured, the option to disable local communication (available in the Home settings) will prevent WiZ products from accepting local UDP messages.

It will restrict communications to encrypted messages going through the WiZ Cloud only.

This option might add a few milliseconds to the response time.
If the Internet connection is down, lights will not be controllable using the WiZ app, even locally.
Disabling local communication will also cause Guest users to lose their access to the lights.
