wassersensor.pulse

The wassersensor.pulse reads your water meter. You connect it to the Node with a cable and attach it to the meter.
Connect the wassersensor.pulse to Port 3 or 4 of the Node if possible. Any port works, but Ports 3 + 4 extend the battery life.
Is this the right sensor?

Water meters with a metallic rotating disc are suitable. If the meter only has a (usually red) plastic wheel, the sensor is not compatible. The marked spot shows the interface you place the sensor on.
Check your meter model in the compatibility list at energieleser.de.
Connecting and attaching the sensor
1. Connecting the sensor to the Node
Plug the sensor's cable into a port of the Node – preferably Port 3 or 4, which gives the longest battery life. You can find which ports are possible for which sensor under Connecting Sensors to the Node.
2. Attaching the sensor to your meter's interface
Next step
Once all sensors are connected and attached, continue with Attaching the Node.
