Introduction to TaHoma Switch

Key features

The Somfy TaHoma Switch is a smart control device designed to easily centralize and automate your smart home. It features two programmable buttons that let you create custom scenarios, providing smart, centralized control of your home. Each button can be configured to trigger a specific scenario, such as "i'm leaving" to close the shutters, turn off the lights, and arm the alarm, or "i'm coming home" to open the shutters and turn on the lights. These scenarios adapt to your daily routine, offering a quick and easy way to manage multiple devices at once with a single gesture—without having to use the mobile app.

The TaHoma Switch is exceptionally easy to install thanks to its compatibility with WiFi, requiring no complex wiring or major technical work. Once connected to your home Wi-Fi network, it’s immediately ready to use, allowing you to control all connected devices via the mobile app. This wireless connection greatly simplifies installation in existing homes or apartments by eliminating the hassles associated with managing electrical systems. Simply follow the setup steps in the app to quickly configure your scenarios and devices.

The TaHoma Switch offers remarkable interoperability thanks to its extensive compatibility with more than 300 product lines from Somfy and partner brands. This includes a wide variety of equipment, such as roller shutters, blinds, lighting, garage doors, gates, security cameras, alarm systems, and smart thermostats.

This compatibility ensures seamless integration of your current and future devices, enabling centralized management. In addition, it works with major home automation protocols such as io-homecontrol, RTS, and Zigbee, making it easy to connect to a wide range of devices.

Somfy's TaHoma Switch allows for intuitive, remote control via a dedicated mobile app. With this app, you can manage your connected devices (shutters, lights, thermostats, etc.)) no matter where you are, in real time. In addition, it is compatible with voice assistants such as Google Assistant, Amazon Alexa, and Apple HomeKit, allowing you to control your home with voice commands. You can customize and schedule scenarios, receive notifications, and monitor device status for optimal management.

The TaHoma Switch was designed to blend seamlessly into any type of interior thanks to its compact and sleek design. Because it is small, it can be placed discreetly on a shelf, a piece of furniture, or a countertop without disrupting the room's aesthetic. Its minimalist design and rounded edges add a modern touch, while remaining neutral enough to blend into a variety of interior styles. In addition, its simple white finish makes it easy to blend in with your home décor.

Benefits for the user

The TaHoma Switch is easy to install and requires no complex electrical work. Here are the main connections required:

• 1. Power supply: plug the TaHoma Switch into a wall outlet using the standard power cable provided.
• 2. Internet connection: Connect the box to your Wi-Fi network using the mobile app. No wired connection is required for integration into your home system.
• 3. Pairing devices: once powered on, use the app to pair compatible home automation devices (shutters, lights, etc.).).

The TaHoma Switch is designed to be ready to use immediately after a quick and easy installation. As soon as you complete the initial setup through the mobile app, you can start controlling your home devices right away. This product is also designed to be scalable, which means you can easily add new devices as your needs grow. Thanks to its broad compatibility with more than 300 product lines from Somfy and its partners, it adapts to the evolution of your smart home without requiring any additional hardware.

Introduction to the TaHoma Rail DIN S

Key features

The TaHoma Rail DIN S is specifically designed for direct installation in an electrical panel using a DIN rail (the standard mounting method for electrical panels). This model occupies 7 DIN units, making it a compact solution that easily integrates into residential electrical installations.

Technical details of the installation

• 1. Installation: easily mounts to a standard 35-mm DIN rail, as used in electrical panels.
• 2. Connection: connect the power wires directly to the panel, ensuring a safe and uninterrupted power supply.
• 3. Programming: Accessible via the TaHoma Pro app, which simplifies equipment installation and configuration without the need for complex procedures.

The TaHoma Rail DIN S is ideal for new construction or major renovations thanks to its direct integration into the electrical panel. When constructing a residential building or a single-family home, the electrical panel is generally installed before the occupants move in. The box can be installed at this stage, thereby integrating it into the building's core electrical system. Similarly, in a complete renovation, replacing or expanding the electrical panel allows for the integration of the TaHoma Rail DIN S to manage all connected devices starting from the reconstruction phase.

The TaHoma Pro app is specifically designed for professional installers to simplify the setup and management of home automation systems. It offers two configuration modes:

• 1. Expert Mode : this mode allows for quick and efficient installation—without requiring an Internet connection—for experienced users. It simplifies the device pairing process.
• 2. Guided Mode : this mode provides installers with step-by-step guidance and a detailed procedure for configuring the box, making it ideal for more complex installations or for less experienced technicians.

This app also centralizes remote facility management, allowing for maintenance work or the addition of new equipment without having to travel to the site.

The TaHoma Rail DIN S ensures full compatibility with all Somfy products that use the io-homecontrol, RTS, and Zigbee protocols. This includes window shutters, garage doors, blinds, thermostats, lights, and other smart devices. This compatibility allows professionals and users to easily add new equipment over time, without the need for complex procedures or hardware replacements. The app's interface allows users to quickly pair new devices, ensuring scalability to meet their future needs.
