Water Pulse Meter

Convert a cumulative water-meter pulse sensor into calibrated liters in Home Assistant.

Many DIY water meters expose a pulse counter rather than a volume. This integration applies a configurable liters-per-pulse factor to the cumulative count, without sending data anywhere.

Features

• Total water volume in liters, marked as a monotonically increasing total for Home Assistant statistics.
• The configured factor is applied to the source's cumulative pulse count plus the starting offset.
