Info about sonoff and yeelight

Hello Guys,
I already have a yeelight system… but I have the probem that when someone at my home switch off the light button I can’t manage the yeelight bulb.
My question is if I install in my home the sonoff wifi switch, if sonoff is in the OFF state, I can manage the yeelight? or I have before to switch the sonoff to the ON state and then manage the yeelight bulb?

If the sonoff will be off, you will not be able to control the yeelight.
But but if you work with Sonoff you dont need the yeelight you can off / on the sonoff switch.

yes… you are right… I’m asking this because I don’t want every time the homeassistant need to reconnect to the wifi bulb…cause it require some time before it connect to hass and if you want to change the rgb colors in few seconds you can’t. @mp3llll
