What Is The Connection Of A Scriber And An Interrupt Routine?
summary
A backyard ground-source heat pump loop of 300 meters goes into the ground and connects to a home interface, metered with a one-pulse-per-watt sensor wired to a Raspberry Pi + GPIO interrupt. A tiny Python interrupt service routine increments an atomic counter on each pulse, the main loop reads-and-resets it every minute, and data lands in InfluxDB and Grafana to show compressor, pump and outside temperature power profiles so the system’s consumption is proven and visualized.
