Yes, it works like a charm !
Well... almost... for some reason the on is off and the off is on.
Its not important for me as I'm not using easyiot cloud web interface. Just curious why 0 turns it on and 1 off (for now I'm using nodemcu09 0 maybe this is the reason)
About the hat... well... I'm the Head Ref at FIRST robotics completions. There are young kids around so I'm wearing this Lego hat I ans with a motor and lights etc.
Now they will be able to turn it on by themselves....
