Domodulo Capsule Button & LED Matrix Kit | ESPHome Smart Display & Switch

Domodulo | Capsule Button & LED Matrix Kit | Modular ESPHome Controller with 10x10 RGB LED Matrix

Take your Home Assistant experience to the next level with the Domodulo Capsule button & LED matrix kit. This innovative and modular hardware platform, made in Belgium, combines physical button control with a versatile graphic display. The kit is delivered fully assembled and pre-installed (with a choice of a White or Black enclosure when ordering), so you can get started right away with visualizing data and controlling your smart wireless switches and automations.

10x10 RGB LED Matrix for Information, Icons and Animations

The most striking feature of this kit is the advanced 10x10 RGB LED matrix module (consisting of 100 individually controllable RGB LEDs). With this display, you can show real-time data from Home Assistant, such as your current energy consumption, indoor temperature, the status of your alarm system, or personalized colored icons and animations. You can configure the LED matrix to wake up as soon as you press the button, or automatically display warnings for specific events at home.

Extensive Tactile Control & 105 RGB LEDs Based on ESP32-S3

In addition to the 10x10 matrix display, this Capsule features 1 button module equipped with 4 of its own RGB LEDs. Combined with the integrated RGB LED and the acoustic buzzer on the baseboard, the device has a total of 105 programmable RGB LEDs for ultimate visual and audible feedback. Thanks to the powerful ESP32-S3 microcontroller and pre-installed ESPHome firmware, everything responds lightning-fast and 100% locally via Wi-Fi to various click patterns (such as a single press, double-click, or long press).

Ecosystems & Compatibility

• Home Assistant: Native support via ESPHome and the official integration. View our Home Assistant category for suitable controllers and accessories.

Pro-Tip from slimhuisje.nl: Use the 10x10 LED matrix as a visual alarm panel on your bedside table. Let the matrix light up red if windows are open when arming the night mode, or display the outdoor temperature as soon as you press the button in the morning! Need help with setup?
