In addition to Tasker actions, it would be very very useful if Yeelight could support events as well. Events are information that the app sends out when a specific thing happens, and Tasker listens to such events and can run an action when they occur.
One very good example would be to send and event when a bulb goes online and offline. This would allow doing something automatically when the physical light switch is flipped on or off. This could also work with light groups and rooms - in such case the event would only be sent when all the bulbs come online or offline.
Hopefully it’s someting you’ll consider adding.
