Maker Max K. has presented OMOTE, an ESP32-based universal remote control with open source code. For the housing, Max relies on 3D printing. He published detailed instructions for his remote control with all the necessary 3D models.
The 2.8-inch capacitive touchscreen, integration of infrared, Wi-Fi and Bluetooth, and optimized power consumption that allows up to six months of use on one charge are just some of the features of this device. Since the design files are open source, customizations to specific devices and needs are possible.
Key features include a 2.8″ touchscreen, ergonomic 3D-printed case, responsive LVGL user interface, and battery life of up to six months with a 2000mAh Li-Po battery. Wake-up is as simple as pressing a button or lifting the remote.
After Logitech discontinued its Harmony remote series, a home-built universal remote was the answer to finding alternatives with improved ergonomics and battery life. Optimizing it for 3D printing and implementing a touch-sensitive and responsive user interface on an ESP32 presented challenges.
