Scenes Transitions without Philips Hue Hub/App

I’ve got Home Assistant OS running on Odroid with ZigBee dongle and zigbee2mqtt. I’ve got some Philips Hue bulbs but no Philips Hue Hub, no Philips Hue app. I’ve got some scenes for the bulbs which I’ve created in HA.

Is it possible to create automation to activate a scene with a transition? And is it possible to have different transition times depending on which event triggered the automation?
