Piazzetta pellet stove (F0203-1480V3 remote): MaximeHTL/piazzetta-433-esphome

An experimental open-source project, piazzetta-433-esphome by MaximeHTL, lets Home Assistant control a Piazzetta pellet stove by emulating its F0203-1480V3 433.92 MHz OOK radio remote, using an ESP32 and an SX1278-based Ra-02 module. The author credits Claude Code (Claude Opus 5.5) with the protocol reverse-engineering, firmware and documentation, while the author handled physical assembly, testing and data collection. The project is confirmed only on one stove and one remote model, warns that it is unaffiliated with the manufacturer, and advises use at the user's own risk on a combustion appliance.

Evidence at a glance Based on the linked sources. The author's reported result and independent confirmation are separate checks. - AI involvement - Reported models: Claude. Tools: ESPHome, RadioLib, Claude Code. The writeup below describes the work attributed to AI. - Reported result - Partial. This is the directory's source-based outcome classification. - Independent confirmation - Not reported. - Human work and limitations - The project explicitly warns that it was reverse-engineered on only one stove and one remote. It is not affiliated with the manufacturer. The author emphasizes that the AI agent performed the analysis and coding, while the author handled the hardware and physical testing. Original sources What was done An experimental project enabling Home Assistant control of a Piazzetta pellet stove by mimicking its original 433 MHz remote. Reverse-engineered using an ESP32 and Ra-02 module, the system supports state monitoring and command execution. The piazzetta-433-esphome https://raw.githubusercontent.com/maximehtl/piazzetta-433-esphome/HEAD/README.md project provides a method to control Piazzetta pellet stoves by emulating the F0203-1480V3 radio remote. The author reports that the system functions as a "dumb terminal" replacement, allowing Home Assistant to read stove states and send commands over 433.92 MHz OOK radio. The project includes an ESPHome component, a test bench for frame capture and decoding, and Home Assistant integration. The author credits Claude Code specifically Claude Opus 5.5 with performing the protocol reverse-engineering, writing the firmware, and drafting the documentation. The author performed the physical assembly, testing, and data collection. The project is currently limited to one tested stove and remote model; it is unknown if the remote id the first byte of the frames is universal or unique to specific pairings. Users are advised that this is an experimental project for a combustion appliance and should be used at their own risk. Reproduce it 1. Build hardware using an ESP32 and an SX1278-based Ra-02 module. 2. Flash the test-bench firmware to capture and decode remote frames. 3. Configure the ESPHome component with the identified remote id. 4. Integrate with Home Assistant for thermostat and dashboard control.
