# Heat & Glo RC300: a Homey client for the reconstructed 433 MHz protocol

> The Heat & Glo RC300 Homey app reimplements 433 MHz commands from the IntelliFire Plus RC300 fireplace remote. Captures made with Homey's RF recorder inform a documented 47-symbol frame layout; the app learns the user's remote address, sends on/off, flame, and fan commands, and receives remote state changes.
