Smart Letterbox Build

Our old letterbox had seen better days—faded, worn, and with the flap barely hanging on by a single hinge. On top of that, couriers often tossed parcels over our gate onto the driveway, one of which my wife accidentally ran over because she didn’t see it. It was clear we needed an upgrade.
So, it was time to build a smarter letterbox—one with a dedicated parcel drop to put an end to our delivery woes.

Installing ESPHome on the Rollease Acmeda Pulse 2 Hub
The Rollease Acmeda Pulse 2 Hub can be repurposed into a powerful ESPHome-based ARC bridge by flashing custom firmware directly onto its onboard ESP32-D0WD-V3 module. The hardware is very similar to the WT32-ETH01 with a physical ethernet port.
This allows direct serial communication with ARC-protocol blind motors, removing the need for the original cloud firmware or mobile app.
