Heat & Glo — IntelliFire Plus RC300

Control a Heat & Glo gas fireplace from Homey, by emulating the IntelliFire Plus RC300 433 MHz remote. The Heat & Glo IntelliFire Plus RC300 is the specific remote/receiver this app speaks to.

What works:

• Fireplace on/off.
• Fan speed (low / medium / high).
• Flame level (1–5).
• Flow actions for setting fan speed and flame level.
• Pairing learns your own remote's address, so the app controls only your fireplace.
• Homey follows the physical remote, using it updates Homey's state.

Like the physical remote, the fan and flame can only be changed while the fireplace is on.

Not supported:

• The remote's AUX1 and AUX2 buttons. They aren't wired to anything on the fireplace this was built against, so no RF was captured for them.

Pairing

Homey learns which fireplace to talk to by listening to your existing remote. When adding the device, hold the RC300 near Homey and press its ON or OFF button. Homey captures the remote's address and transmits as that remote from then on.

Protocol

The 433 MHz protocol was reverse-engineered from captures made with Homey's built-in RF signal recorder. See RF_PROTOCOL.md for the frame layout, the decoded payloads, and how to capture and decode additional commands.
