CpapDashThe engine behind CpapDash is open.
CpapDash is built on a stack of open-source services that read CPAP data straight from the machine, stream it to the cloud, and turn it into something you can actually read. They run on a Raspberry Pi, an ESP32, or your own server — no vendor lock-in, no cloud you don't control.
C++ service that collects ResMed & Lowenstein therapy data from the machine's WiFi SD card, computes standards-based metrics, stores them to PostgreSQL, and publishes live to MQTT for Home Assistant.
Dual ESP32-C3 bridge over UART: the Miner reads the CPAP's WiFi SD card, the Mule streams each night's files to the cloud over your home WiFi. Fully automatic, nothing to plug in each morning. Ships with a 3D-printed copper-tape "PCB" you can build yourself, no fab required.
HTTP file server firmware for the FYSETC SD WiFi Pro (ESP32) — serves SD-card therapy files over WiFi with an ezShare-compatible API any client can read.
Dual-mode firmware for the FYSETC SD-WiFi v2.1 (ESP8285) — serves ResMed therapy data straight off the SD card over WiFi and MQTT. A single-board alternative to the Mule & Miner.
The parsing core used by hms-cpap and CpapDash: a shared C++ library that decodes ResMed and Lowenstein therapy files into standards-based metrics.
The Angular chart component library that powers CpapDash's visualizations — reusable, themeable therapy charts shared across the CpapDash apps.

The Mule & Miner ships these services pre-configured — stream your therapy data with nothing to set up.
