The output from the water meter reader, published in MQTT, are:
- Average flow last minute (liter/minute)
- Average flow last 10 minute (liter/10minutes)
- Consumption last drain (liter). The number of liters between the last two times with no consumption.
- Total consumption (liter)
The leakage monitoring is very simple. It uses only value 1 and checks if the flow > 0 during a couple of minutes. The accepted duration is very low at night and when nobody is at home.
All info about the used software you will find earlier in this thread.
