Eniris Pulse‑based Water Meters
Supported Devices
The integration is intended for any water meter that offers a clean pulse
output (normally‑open or normally‑closed contact). Typical examples are the
popular ZENNER, Itron, Kamstrup, or Sensus models equipped with
pulse modules – but any dry‑contact 1 pulse = x l counter will work.

Wiring
Pulses are read via the digital input (DIA/DIB) of the Controller or Smart Grid Controller. Wire the meter’s open‑collector or reed switch as illustrated below:
- Polarity does not matter for dry contacts.* Use twisted pair cable for long distances (> 10 m) to minimise interference.
Configuration in the Eniris Portal
- Add a new device and select “Generic Digital Input → Water Meter”.
- Choose the digital input (DIA or DIB) you have connected the meter to.
- Enter the pulses per m³ (e.g.
1000pulses/m³ for many domestic meters). - Save — the driver will immediately start logging cumulative consumption and flow‑rate.
Tip : If you see negative deltas, invert the wiring or change the input logic from normally‑open to normally‑closed in the device settings.
Metrics exposed
| Key | Description | Unit |
|---|---|---|
flowRate_lps | Instantaneous flow rate | L/s |
importedAbsWaterTot_l | Total volume consumed | L |
importedWaterDeltaTot_l | Delta volume since last period | L |
All metrics are stored in the waterMeterMetrics measurement and retained
with 1 s resolution by default.
Troubleshooting
- No data? Check that the contact actually toggles using a multimeter or LED tester, and verify the correct digital input is selected.
- Erratic pulses? Add a 1 kΩ pull‑up resistor or enable the built‑in pull‑up in the controller.
- Flow too high/low? Confirm the pulses per m³ factor from the meter datasheet.
