Power Supply

Your Node can be powered in two ways: with batteries or via USB-C. For batteries, you can choose between two variants — use whichever suits your installation.

Option A: Batteries

Variant 1: Long-lasting battery + battery dummy (recommended)

The long-lasting battery is included with the Node and lasts the longest. The battery dummy is a spacer that completes the circuit in place of a second cell.

1. Open the battery compartment.
2. Insert the long-lasting battery in one slot, and the battery dummy in the other, matching the + and – symbols shown inside the compartment.
3. Close the compartment.

Variant 2: Two AA batteries

Also possible. However, AA batteries do not last as long as the long-lasting battery.

1. Open the battery compartment on the back of the device.
2. Insert two AA batteries, matching the + and – symbols shown inside the compartment.
3. Close the compartment.

Option B: USB-C power

Possible if a power outlet is within reach.

1. Open the battery compartment. The USB-C port is located beneath the space for the batteries.
2. Remove the small rubber cover on the battery compartment flap.
3. Guide the USB-C cable through the opening and plug it into the USB-C port.
4. Close the battery compartment and plug the power supply into a nearby outlet.

First start

A Node that has not been paired with a Bridge yet briefly shows the LED for Port 1 after you insert the batteries (for up to about 10 seconds). A Node that is already paired switches straight back to energy-saving mode with no LED at all. What the individual LEDs mean is explained under LED Indicators.

Reading intervals

• Battery operation: The Node takes a reading every 15 minutes.
• USB-C power: The Node captures power values every 5 to 10 seconds and meter readings every minute.
