readily available apps are: mihome and yeelight. if you want DIY - node-red, hass, domoticz - and you can control it with anything you can imagine. not sure on 3rd party apps on play store.
can those be added in apps like all4hue, where i control all my hue-compatible bulbs or do i need to control them through Mi Home app?
no, it doesnt need gatewat BUT if you put it on chinese server these will be visible in your gateway. IMPORTANT INFO!: YEELIGHTS LIGHTS ON CHINESE SERVER NOW WORK WITH GOOGLE HOME!!!! !!!!!
I've expired this as the original code has expired but the other two at the top are still working at the moment
Does it connect with the gateway?
