# ESP32 Controller for Charlton & Jenrick Fireplace: reconstructing remote control

> ESP32 Controller for Charlton & Jenrick Fireplace recreates remote commands by transmitting captured RF payloads through a CC1101 module. Its firmware provides iRange 2-FSK and non-iRange ASK/OOK profiles, with controls exposed through a web interface, MQTT and Home Assistant.

## Requirements & limits

- **Prerequisites:** ESP32-WROOM-32, a 3.3 V CC1101 433 MHz module, and PlatformIO with the Arduino ESP32 framework.
- **Testing evidence:** The author reports testing i1800e and 1800E; other listed fireplace models remain untested.
- **Limits:** The CC1101 misses some remote transmissions, so the physical remote cannot stay synchronized with this controller.
- **License:** MIT licence.
