Home Assistant Glow is an open-source project that turns an ESP32/ESP8266 microcontroller with a photodiode into an energy meter reader for utility meters that lack a P1 port, by detecting the meter's pulse LED. It provides ESPHome-based firmware installable via ESP Web Tools and integrates the measurements into the Home Assistant Energy dashboard.
Use cases
- read energy consumption from a meter without a P1 port
- track household electricity usage in Home Assistant
- measure kWh and watt usage via a meter's pulse LED
- build a DIY smart meter with ESP32 and a photodiode
- feed the Home Assistant Energy dashboard with real consumption data
- monitor energy usage hidden in a meter cupboard with a 3D-printed case
When to choose
- your utility meter has an imp/kWh pulse LED but no P1 port
- you already use Home Assistant and want native energy dashboard integration
- you want a cheap DIY hardware solution with ESPHome firmware
- you prefer browser-based firmware flashing with ESP Web Tools
When to avoid
- your meter has a P1 port or native smart meter integration available
- you need gas or water metering rather than electricity pulses
- you don't use Home Assistant and want a standalone energy monitor
- you are unwilling to assemble simple hardware (photodiode, jumpers, ESP board)
