An ESPHome based Home Assistant integration for controlling a Sony TC-WE675 Tape deck over its A1 Control serial port.
Would probably work on other Sony A1 tape decks, and could likely be expanded to support other Sony A1 audio equipment.
- /esphome - esphome YAML code
- /homeassistant - sample HACS/media_player_template entity and lovelace cards
- /util - code timing conversion utilities
- /pcb - EagleCAD files for hardware build
- /enclosure - OpenSCAD and STL files for 3D printing enclosure
Protocol based in part on the A1/S-Link reverse engineering work of:
