I saw a lot of possibilities to add the Yeelight bulb 
but none optimized. For now as I have a Robockock vacuum, I went for Xiaomi Mi I/O binding Xiaomi Robot Vacuum Binding from @marcel_verpaalen. Works really great 
for the vacuum ! My question is more about the yeelight. I have seen on other platform the possibilities to connect the lights without token.
Is the yeelight connection without token could come to this binding ?
Is there an updated binding giving me this possibility ?
Before I start moving my yeelights from server to get it in mi home app and extracts this token.
Of course the bulbs are in dev mode and currently working with an other controller.
PS: i saw the yeelight binding but I think I read that it is not mantain ?
