⚠️ Warning: If the voice assistant doesn't see the light bulb, check: The light bulb and the phone are connected to the same Wi-Fi network. In Mi Home, the device is tied to the same region as the account (for example, "Russia", not "China"). In the settings of the assistant app (Yandex)./Google Home) Local area network access allowed.

💡

If Alice doesn’t recognize the light bulb’s name, try renaming it Mi Home using simple words without spaces (e.g., “lamparoom” instead of “lamp in the room”).

5 Automation and Scenarios: From Simple Timers to Complex Rules

The true power of smart light bulbs is revealed in automation, and let's look at the options from simple to advanced.

• ⏰ Timers: time-on/off, for example, simulated home presence ("On at 20:00, off at 23:00»).
• 🌅 Schedule: smooth awakening (increase in brightness from 6:00 to 7:00).
• 🔗 Scenarios: Action combinations, like "Cinema": turn off the main light, turn on the backlight at 30% brightness, and set the blue color.
• 📱 Conditional Automation (only in Mi Home): "If the phone connects to home Wi-Fi, turn on the light bulb».

How to create a script in Mi Home:

1. Open the tab "Automation» → «Add».
2. Select a trigger (time, location, action of another device).
3. Specify the action for the light bulb (brightness, color, on / off).
4. Save and activate the script.

💡

For advanced automation (such as communication with motion sensors or weather conditions), use Home Assistant or Node-RED. These platforms allow you to create rules like “If it rains and is dark outside, turn on 70% warm lights.”

An example of a complex scenario:

1. Trigger: The Xiaomi Motion Sensor detects movement.
2. Condition: Time between 18:00 and 22:00.
3. Activity: Turn on the bulb at 80% brightness with color temperature 3000K.
4. If there is no movement for 5 minutes, turn off the lights.
