stromsensor.S0
Hazard: The meter on which the stromsensor.S0 is installed is connected to mains voltage.
Possible consequence: Touching live parts can cause a life-threatening electric shock.
Action: The installation must be carried out by a qualified electrician only. Do not carry it out yourself. Do not open meter, fuse or distribution cabinets, and do not touch exposed wires or contacts.

The stromsensor.S0 reads electricity sub-meters with an S0 interface. You connect it to the Node with a cable and place it on the meter.
Connect the stromsensor.S0 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?

Your meter fits the stromsensor.S0 if you find an "S0" label on it. 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
The installation at the meter must be carried out by a qualified electrician only – see the warning at the top of this page.
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.
