You only need lights when it is dark and there somebody in the room to use it. Both conditions are easy to automate. With the price of motion sensors and smart lights, there are no reasons we need to use the switches anymore.
This routine is part of the Automation Bank, a community-driven list of over 50 practical automation ideas for your smart home. Read more about Automation Bank or search ideas by room, by device or by use case. Also, have a look at best home automation ideas as voted by our users.
We believe that light automation is one of the first things you need to do for your house and below is the guide on how to do that.
How Does It Work?
- There are two ways you can smarten your lights.
- Install a smart switch. The benefit of this is that you will save on the bulb costs and nobody will accidentally switch off the dumb lights. Cons is that you cannot control the color/brightness and so on. You also need a neutral line in the box with your switch.
- Install a smart bulb. The cons are that it is usually more expensive and somebody can switch off the smart lights using a dumb switch.
- Another important element is the motion sensor.
- Make sure that you install it in the right spot to cover the whole of the room and also avoid false triggers
- Make sure that your motion sensor will also have a luminance sensor. It will allow you to also detect when it is dark enough in the room to switch on the lights. You can rely on time, but the luminance sensor is a much more reliable approach.

- Grohe 22503LN0 (from $14.00) is even more expensive. For the additional price, you have flow sensors capable to detect the pipe bursts without the sensors and better overall build quality. At the same, it has fewer options for integrating with your smart hub.
$99 - $400
Door/Window SensorReports if a door or window is open or closed
$20 - $30
Motion SensorDetects any motion. Ideally combined with luminance sensor.
A relatively simple device, with the price mainly dependent on the protocol you are using:
- Z-wave Motion Sensor: Our favouritez-wave sensor is Dome Motion and Light Sensor ($40.57) for a good battery life, responsiveness and price. It also has luminance sensor built in. For a multisensor we recommend Zoos 4 in 1 multisensor ($36.95) or Aeon 6 in 1 ($59.99).
- Zigbee Motion Sensor: SmartThings sensor ($24.41) is the best for its price and stability.
$25 - $60
MultisensorMeasure several environmental factors such as temperature, humidity, or light levels
This is a more complicated device than a motion sensor and can be used where multiple environmental factors need to be detected:
- Z-wave: Our favourite z-wave sensor is Aeon 6 in 1 ($59.99) for its reliability and flexibility in use. It detects motion, humidity, temperature, light lux, UV, vibration sensor and has 2-year battery life
- Zigbee: Samsung SmartThings Multipurpose Sensor ($19.68) give you open/close, vibration, orientation, angle (tilt), and temperature measures for multipurpose functionality
$20 - $60
Water leak detectorA sensor that will trigger the shut-off valve to work
- Samsung Leak Detector ($19.53) is the most affordable and simple solution. At this price, you should cover all the areas in your house. Requires A Smart Hub
- FIBARO Flood Sensor ($62.99) is a very good Z-wave leak detector. It has great battery life, easy to pair and very accurate at alarms. Requires A Smart Hub
$20 - $55

Voice assistant:AI driven device that can respond to voice commands
There is no right answer which Voice Assistant to choose, but we have the following recommendations:
- The most comprehensive: Amazon Alexa ($99.99) has a lot to offer. Zigbee radio means potentially one hub less (although we still recommend getting a dedicated hub). It also has the biggest ecosystem to tap into (including Ring, Phillips Hue, TP-link)
- The most intelligent: Google Home is using the brains behind the biggest search engine in the world to deliver the best answers for your questions. It is definitely more capable compared to Alexa

How to Set Up?
Section below will have step by step instructions how to set this automation routine in the most popular smart hubs like SmartThings, Home Assistant, HomeSeer and Hubitat
Please leave comments below if you have any questions, or interested in the instruction for a specific system. This will help us to better focus our effort.
Setting in this up in Home Assistant
Setting this up consist of three main parts. I am will give you a live example that I run on my smart home setup (See my Github for details).
1. Connect your switch/bulbs and motion sensor to your system
As the example, I have a night lamp in my bedroom that I use as the secondary light. I am using Yeelight which is a color bulb. I decided to pay more for color because I am also using it for notifications (time to sleep and windows downstairs are open)
Yeelight bulbs easy to integrate and they usually auto-detected by Home Assistant. In my case, I decided to hard code it in my configurations.yaml
yeelight: devices: 192.168.1.17: name: Bedroom
For a motion sensor I am using Aeon 6 in 1 ($59.99). As with all Z-wave devices, it does not require any config changes.
2. Create automation rule to switch on Lights.
Automation rule is simple – if there is a motion and it is dark, switch on the bulb.
- id: kitchen_lights_on alias: kitchen lights on trigger: - platform: state entity_id: binary_sensor.aeon_labs_zw100_multisensor_6_sensor from: 'off' to: 'on' - platform: numeric_state entity_id: sensor.aeon_labs_zw100_multisensor_6_luminance below: '12' for: hours: 0 minutes: 5 seconds: 0 condition: condition: and conditions: - condition: state entity_id: binary_sensor.aeon_labs_zw100_multisensor_6_sensor state: 'on' - condition: numeric_state entity_id: sensor.aeon_labs_zw100_multisensor_6_luminance below: '10' action: - service: switch.turn_on entity_id: switch.kitchen_lights
Use Multiple Triggers
Note that I am using multiple triggers. This is to cover situations when you are cooking in the kitchen for a long time. In those situations, the motion sensor will be always on, but once it gets dark you would want your lights on.
3. AUtomation rule to switch off lights
This step is equally important. You need to set up automation to switch off lights as well as switch them on.
- id: kitchen_lights_off alias: kitchen lights off at night trigger: - platform: state entity_id: binary_sensor.aeon_labs_zw100_multisensor_6_sensor from: 'on' to: 'off' for: hours: 0 minutes: 10 seconds: 0 - platform: numeric_state entity_id: sensor.aeon_labs_zw100_multisensor_6_luminance above: '12' for: hours: 0 minutes: 10 seconds: 0 condition: condition: state entity_id: switch.kitchen_lights state: 'on' action: - service: switch.turn_off entity_id: switch.kitchen_lights
There is a more elegant solution using wait_template. It basically would allow to combine both on and off automations in the single automation. I want to make sure that my condition “there is no motion for 10 minutes” can be implemented as well, but most likely to switch to wait_template soon. See more details here
