Sonoff alexa integration, without HA cloud, but integrated into HA

Hi guys!
So i have a couple of sonoff plugs and Philips Hue lights. My intention is to get a Sonoff RF Bridge and sensors that i can use with both the Hue lights and the Sonoff plugs, but i don’t want to pay for the HA cloud. So is there a way that i can still use the plugs with Amazon Alexa (i thought of wemo simulation, but haven’t flashed any sonoff yet) and integrate them into Home Assistant? Philips Hue still works with Alexa without HA being connected to Alexa.
