Embedded & IoT engineer — energy metering · CAN bus · reverse engineering · ESPHome
I build firmware and tools that live at the boundary between hardware and software: reading electricity & water meters, sniffing automotive CAN buses, and reverse-engineering embedded devices. Most of my open work ships as ESPHome components for utility meters, plus the protocol libraries underneath them. When I'm not on a serial bus, I'm designing PCBs in KiCad.

I'm an active contributor to the official ESPHome project, where I've authored and maintain a number of sensor, display, and accelerometer components that now ship with ESPHome itself. (merged PRs · all PRs)

…plus fixes & enhancements to LTR390, INA226, VEML7700, BME280, the ac_dimmer (ESP-IDF 5+),
and the i2c bus.
I'm also one of the main developers of esphome-libs/dlms_parser — the shared DLMS/COSEM parsing library used across the ESPHome ecosystem, which grew out of my own esphome-dlms-cosem work.
In progress (open PRs): AS7341 / AS7343 spectral sensors, HUSB238 USB-PD controller, ST LIS2DH12 & LIS2DW12 accelerometers, Waveshare CH32V003 I/O expander, CST328 touch controller, BH1745 colour sensor, and signal filters.
