If we set our bulbs to developer mode, then surely we can create a smartthings device handler to control? We would not need to contact the cloud? I am trying to cobble this together, however, I am far from an accomplished developer. Is there any decent code that you can point me at to use as a starting point. I am most keen to ensure the interaction is two way. (ie get the device properties available in smartthings)
I set up node-red and successfully controlled a light using the npm published yeelight nodes. So I am pretty sure this is feasible.
