Wired Communication to the Backup Gateway

As an alternative to wireless communication with the Neurio meter, it is possible to establish wired communication between the meter and the Gateway using an optional 2-conductor meter communication harness (Tesla P/N 1133339-00-x). Up to two meters can be wired directly to the Gateway.

Note
The Neurio meter can only be wired to the Backup Gateway; it cannot be wired to a Controller Powerwall+.

The meter antenna is always required, even if the meter is located inside the Backup Gateway enclosure or connected to the Gateway using the optional wired communication harness.

Note
Tesla recommends connecting the meter via wireless Wi-Fi rather than using a wired connection. This is because the meter receives firmware updates with new features and improvements, but only if the meter is communicating to the Gateway via Wi-Fi. Firmware updates are not possible when the meter is using wired communication. If you must use wired communication, connect the meter to the Gateway wirelessly first to update the meter firmware, then transition to wired communication.
  1. Plug the 2-conductor harness into the port on the top of the meter.
  2. Connect the harness leads to the Backup Gateway Meter Communication ports by inserting them into the corresponding connector, according to the following table and diagram.
