Low voltage refers to any voltage below 50 volts. Therefore, 12 volts is classified as low voltage.

12-volt lighting can be used in any garden, whether large or small.

• No electrician is required for installation, as it’s easy to install everything yourself.
• Unlike a 120/230-volt system, the cables do not need to be buried at least 50 cm under the ground.
• It is very safe for children and pets.
• It is easy to expand and quick to connect.

No, the voltage used does not directly affect the light output of a light source. The number of lumens indicates the amount of light a lamp produces.

The number of lumens corresponds to a lamp’s light output. The higher the lumen value, the more light the lamp provides. Our lighting products offer a higher lumen output than most fixtures on the market.

Wattage refers to the electrical power used. With incandescent lamps, wattage was often used to indicate brightness. However, with the advent of LEDs, brightness is now measured in lumens.

Depending on where you want to place your lights in the garden, you can choose the appropriate IP rating to ensure your lights keep shining, no matter the weather. Some IP values you should know:

• IP44: Handles minor water splashes. Ideal for lights exposed to light rain but not direct jets of water.
• IP65: Protects against powerful water jets from all directions. Perfect for lights exposed to heavy rain or located near fountains.
• IP67: Suitable for lights close to the ground or at risk of temporary submersion. Dust-tight and submersible for short periods.
• IP68: Designed for permanent submersion. Ideal for underwater lighting in ponds or swimming pools.

Our lighting products are IP67 rated.

Yes, the switch retains its status if the power is lost.

Yes, the light source retains its status when the power is lost. Once power is restored, it resumes its previous state (e.g., brightness or color temperature).

You cannot connect a 12 V lamp to a 120 V system, or vice versa.

Besides 12-volt lighting, you need a transformer, main cables suitable for outdoor use, and waterproof wire connectors.

No, 12-volt lighting should be connected to the transformer, which can then be plugged into a standard power socket.

A transformer is needed to convert the 230 volts from the power socket into 12 volts. The low-voltage lighting system won’t work without it.

By adding up the wattages of all your lamps and accessories, you get the total load. Based on this, you choose a 24 W, 100 W, 150 W, or 300 W transformer.

No, the transformer can be connected to any standard power socket, whether earthed or not.

This depends on your lighting plan. Look at where the power socket is and then where you want to place the lights. The cable must be long enough to run from the power source to each light.

Connect the fixtures to a main cable rated for outdoor use—SPT-3 type with a minimum temperature rating of 60°C. Choose the appropriate wire gauge based on the longest distance between the fixture and the transformer:

• 8 AWG: up to 250 ft (76 m)
• 10 AWG: up to 150 ft (45 m)
• 12 AWG: up to 100 ft (30 m)

The main cable can be extended using waterproof wire connectors. However, it’s not recommended to extend the cable attached to the fixture itself. Instead, it’s best to place the main cable as close to the fixture as possible.

The number of lamps you can connect to a cable does not depend on the cable, but on the total wattage supported by the transformer.

Yeismooi’s lighting system operates on 12 volts, which is low voltage. Low-voltage cables do not need to be buried. Make sure the cables are placed safely, to avoid damage from shovels or animals chewing on them.

Yes, you can choose to leave them exposed or conceal them under soil, gravel, or tiles. You may also run them along the back of a garden border to keep them out of sight.

The cable distributor can be used if you don’t have enough connection points in your wiring system. It allows you to connect three lights to one point. You can also use it at the transformer, enabling two or three main cables to run directly from it. Alternatively, use the distributor to branch out from a connection point where a lamp is already connected—by placing the distributor in between, you can connect the lamp and an extension cable at the same time.

The transformer must always be connected to an active power socket for the lights to work.

Wi-Fi is a technology that allows devices to connect to each other over a wireless network. Wi-Fi uses radio waves instead of cables to provide high-speed wireless internet access.

2.4 GHz refers to the frequency band at which the Wi-Fi signal is transmitted. Wi-Fi on the 2.4 GHz band has many benefits, such as a strong signal that can pass through walls, doors, and ceilings. This provides greater range.

Our products only support 2.4 GHz and do not work on 5 GHz networks.

The 5 GHz band has a shorter range compared to the 2.4 GHz band because higher frequencies have a harder time penetrating solid objects. In contrast, the 2.4 GHz band offers longer range but at lower speeds. The 5 GHz band provides higher speeds, which are useful for tasks like video streaming. However, this has no added value for Yeismooi products.

No, device pairing requires a 2.4 GHz Wi-Fi connection.

During device pairing, your phone must be connected to a 2.4 GHz Wi-Fi network and have Bluetooth enabled simultaneously. For daily use, YEISMOOI lights communicate via Thread Mesh rather than Bluetooth.

Thread is a low-power, wireless mesh networking protocol designed specifically for smart home and Internet of Things (IoT) devices. Unlike traditional Wi-Fi, which relies on a central router, Thread allows devices to communicate directly with each other in a mesh network—extending coverage and improving reliability. This makes it especially suitable for outdoor garden settings. Thread is secure, responsive, and energy-efficient, ideal for smart lighting, sensors, locks, and other connected devices.

Wi-Fi, by contrast, is designed for high-bandwidth applications like video streaming and web browsing. It offers faster data speeds but consumes more power and relies on a single central access point. Thread is slower but far more power-efficient and scalable for smart home ecosystems.

Thread creates a robust and reliable mesh network where communication hops from device to device, increasing range and resilience without relying on a single access point. This makes it especially effective for outdoor garden environments. Thread is also optimized for low power consumption, making it ideal for battery-powered devices.

• It allows you to control multiple light scenes with button clicks (without openning App).

• It allows you to enjoy Alexa & Google voice control.

• It creates lighting mesh network that supports for better coverage of yard lights.

Yes, pair the Yeismooi Switch Hub first before adding the lights to the app.

You must provision a Yeismooi Smart Switch Hub first.

• Automatically enters pairing mode on first power-up.
• To manually enter pairing mode: Press and hold the top-left and bottom-right buttons simultaneously for more than 10 seconds (with the power cable facing up). When the four indicator lights flash in a blue circular pattern, it enters pairing mode.
• If the Switch Hub is deleted from the Yeismooi App, it will automatically enter pairing mode when powered on.
• Pairing mode will last for 2 hours.

• Automatically enters pairing mode on first power-up.
• Turn the lights on and off 5 times, keeping it on for 3 seconds each time before turning it off.
• Or delete the device from the Yeismooi App.
• Pairing mode lasts for 2 hours, and the light will flash in a breathing pattern.

The Yeismooi App works on most iOS and Android phones.

• Switch Hub:
  • Please check your WiFi network connection.
  • Keep your Switch Hub closer to WiFi Router.
• Lights:
  • Check whether the Switch Hub is online and connected.

If your app is having trouble communicating with Yeismooi devices that you’ve already added to your system, try the following steps:

• Check if another family member accidentally deleted the device.
• Ensure all devices are powered on. For offline lights, verify that the Switch Hub is powered and online.
• Refresh the Yeismooi App by pulling down the home screen.
• If the device still isn’t found, manually enter pairing mode and select “Add Device” in the app.
• If problems persist, contact support at support@yeismooi.com.

Yes, once devices are added in the Yeismooi App, you can control them remotely via 4G/5G. If your phone is on the same Wi-Fi network as your devices, local control is enabled automatically for faster performance.

Yes, you still can control lights even when they are shown offline in the App under below circumstances:

1. When your mobile phone connects to the same WiFi as the Switch Hub, the WiFi is currently not connected to the internet:

• The existing schedules on devices would work automatically.
• The existing manual controls (scenes) would still work via both mobile App and Swich Hub Buttons.
• But you cannot create any new scene or schedule unless your home WiFi resume normal.

2. When your mobile phone is on mobile network:

• App control may not work as the devices have no more access to internet.
• You can control lights only via Switch Hub Buttons with the bundled scenes.

No, a light can only be assigned to one Zone (e.g., Front Yard or Back Yard), but you can include it in multiple scenes.

• Click here to watch the how-to video.
• Open the Yeismooi App: Ensure the Switch Hub and lights are added.
• Go to the second tab “Scene” > “Recommend”, then select “Turn off lights at sunrise” or “Turn on lights at sunset.”
• Choose the lights and set actions, such as gradually turning on the lights over 15 minutes to 75% brightness and 3000K color temperature.
• Save the scene.

Note: These scenes will automatically calculate adapative timing based on which city you are located, so ensure the app has location permissions enabled for accurate timing.

Up to 15 schedules and 30 scenes per home.

Thanks to Thread, you don’t need to be close. Just sign in to the Yeismooi App and control your lights from anywhere.

It can cover up to approximately 70 meters, depending on your home environment and obstacles. While Thread enables a broader, more robust, and reliable mesh network. Two Switch Hubs for a large house can be considered due to typical home environments and physical barriers(e.g., separate front and back yards).

Voice Control allows you to control lighting devices and scenes using voice commands. Yeismooi supports Alexa and Google Assistant. Learn more here.
