Currently the Sensor → IFTTT → Bulb has 4-10 seconds delay maybe due to various reasons. But I think it would be best to have a direct trigger from the sensors to the wyze bulbs like how the the wyze sense to wyze camera with only 1-3 secs delay only.
@Edgy, have you explored the Shortcuts feature of the app? Using Shortcuts, you can use Wyze Sense events to trigger actions on the bulbs. More info on Shortcuts is available in the Support link, top right.
