Use lights in Yeelight App offline

Is it possible to control my Yeelight bulbs with the app using Lan (no internet connection). The lag is simply too much when using it online

You can turn on “LAN Control” in device control page.

I already did that but the app still uses my internet connection to send the command to Yeelight servers which in turn turns on my lights. It does not use LAN even though LAN mode is activated.
