Domodulo Capsule Double Button Kit | Modular ESPHome Smart Controller

Domodulo | Capsule Double Button Kit | Modular ESPHome Scene Switch with 9 RGB LEDs

Give your smart home a stylish, physical, and direct control interface with the Domodulo Capsule double button kit. This innovative hardware platform, designed in Belgium, is specifically engineered for seamless local integration with ESPHome and Home Assistant. Great news: this kit comes fully pre-installed! All you need to do is choose your favorite color (White or Black). With two tactile button modules, a powerful ESP32-S3 microcontroller, an acoustic buzzer, and no fewer than 9 programmable RGB LEDs, you can expand your network with ultimate control over scenes, lighting, and wireless switches throughout your home.

Supplied Ready-to-Use, Based on ESP32-S3 & ESPHome

The Domodulo Capsule is built around a powerful Core module featuring the ESP32-S3-MINI MCU with pre-installed ESPHome firmware. The complete kit is delivered fully assembled, so you can get started right away without complicated installation. The well-thought-out snap-fit design also makes the housing extremely durable and easy to maintain or expand. Because the Capsule works 100% locally via Wi-Fi, you are never dependent on an external cloud or slow servers: every button press is processed instantly and without delay within your own network.

Maximum Control with 9 RGB LEDs, Buzzer & Click Patterns

Unlike standard wireless buttons, the Capsule double button kit features extensive visual and acoustic feedback. The kit contains a total of 9 programmable RGB LEDs: 4 LEDs per button module (8 on the front) that illuminate the buttons and the transparent front frame brightly, plus 1 specific RGB LED on the base board that provides atmospheric lighting for the underside and back. Combined with the built-in buzzer on the base module, you can easily provide acoustic and visual status notifications. Link different click patterns via ESPHome (such as single press, double-click, or long press) to dim lighting, operate the alarm, or start your robot vacuum.

Includes Wedge Tool & Smart Accessories

Every Domodulo Capsule Kit comes with a plastic Wedge Tool as standard. Use it to open the pre-installed snap-fit housing without scratches or damage, which comes in perfect when you want to customize the look of the buttons later with the optional 12-piece button set. The Wedge Tool also features a printed QR code that leads directly to the online Domodulo manual. Because the USB-C power port is located on the back, we recommend ordering the wall mount bracket or the desk stand for a clean, sleek installation.

Ecosystems & Compatibility

• Home Assistant: Native support via ESPHome and the official integration. Check out our Home Assistant category for suitable controllers and extensions.
  

Pro-Tip from slimhuisje.nl: Use the rear RGB LED on the base board as a subtle nightlight or status indicator (e.g., red when the alarm is armed). You can set the 8 front LEDs to light up green briefly upon a successful action! Questions about configuration? Join the official Domodulo Discord channel for active community support.

Frequently Asked Questions (FAQ)

Do I have to assemble the Domodulo Capsule double button kit myself?

No, the kit is delivered fully assembled and pre-installed. When ordering, you only need to choose which color housing you would like to receive: White or Black.

How do I pair the Capsule kit with Home Assistant?

Thanks to the pre-installed ESPHome firmware, the Capsule is automatically discovered via mDNS in Home Assistant after connecting to your Wi-Fi network. With a single click on 'Add' on your integration page, the scene switch is immediately operational.

How exactly do the 9 RGB LEDs work?

In total, this kit contains 9 RGB LEDs. Both button modules each feature 4 RGB LEDs (8 in total on the front) for button and edge lighting. The base module also contains 1 extra RGB LED on the back for atmospheric background lighting on the wall or table.

What is the included Wedge Tool for?

The Wedge Tool is a handy plastic opening tool that allows you to open and close the housing without scratching it, for example, to attach button covers from the 12-piece button set. The printed QR code takes you directly to the online Domodulo manual.

Which accessories are recommended for installation?

Because the USB-C port is located on the back, we recommend the wall mount bracket for a flush wall attachment or the desk stand for placing it on a table. Would you like icons on the buttons? Then order the 12-piece button set as well. For any questions, you can also visit the official Domodulo Discord channel.
