CpapDash
OPEN SOURCE

The 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.

hms-cpap
CPAP data collection service

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.

Mule & Miner — wireless CPAP bridge

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.
