Currently in development: ESP version with ESPHome/Home Assistant control and configuration.
1/2026 modifications
- Changed magnet mounts to glue-in (10x3mm) for better attachment and easier printing
- Reversed and improved feet-to-leg mount pins for stronger and more accurate installation
- Added drainage routes for water infiltration (recommend a waterproof speaker cone for outdoor/wet conditions)
