Smart Home Scene Linkage (Legacy)

Provide scene automation capabilities on the smart home app, and enable multiple devices to simultaneously perform different actions when a preset trigger condition is activated. For example, this condition can be associated with any device, time, or environment. For example, automatically turn on the air conditioner before the user arrives home, turn on the air purifier when PM2.5 exceeds 100, or send an alarm and even make a phone call if any smoke is detected.
