Turn your Commodore 64 into a fully functional Home Assistant control interface.
Not just a dashboard — HomeTo64 lets you control lights, switches, locks, fans, covers and more directly from the C64 keyboard, while displaying live sensor data from your smart home in real time.
What is HomeTo64?
HomeTo64 is a Home Assistant custom integration that brings your smart home to a Commodore 64 (or C128) via the Ultimate 64 FPGA board or 1541 Ultimate II+ cartridge REST API.
Using DMA writes directly into C64 screen RAM, sensor values update live with no screen flicker, no reset, and no typing required. But the real breakthrough in v1.2 is bidirectional control — the C64 keyboard becomes a remote control for Home Assistant. Navigate your sensor pages with cursor keys, select any controllable entity, and press Return to toggle it. The response is near-instant.
This is believed to be the first Home Assistant integration to provide full bidirectional control with a Commodore 64.
