Tesla Wall Connector (Gen 3)

Quick verdict

The Gen 3 Tesla Wall Connector is a strong local-first value: an official Home Assistant integration polls it directly on your LAN with no account, exposing session/lifetime energy, temperatures, and status codes. The catch is it is monitor-only - HA can read it but cannot start/stop charging or set amperage. For local energy visibility on a well-priced 48A charger, it is hard to beat.

Standout: One of the few EVSEs with an official, fully local Home Assistant integration - account-free energy and status monitoring over the LAN.

Compatibility snapshot

Why it stands out

• Official Home Assistant integration that polls the Gen 3 unit locally over Wi-Fi - no cloud account
• Exposes useful local sensors: session/lifetime energy, status/error codes, handle and PCB temperatures, grid frequency/voltage
• Adjustable 12-48A hardware output; widely available and works with any J1772/NACS EV via the right plug

Reasons to hesitate

• Read-only in Home Assistant: the local API gives sensors but no start/stop or amperage control from HA
• Only the Gen 3 (Wi-Fi) Wall Connector has the local API; older units do not
• Power-sharing and scheduling live in Tesla's own app, not exposed for control in HA

Best for

• Anyone who wants local, account-free energy monitoring of their home charger in HA
• Tesla and non-Tesla EV owners who want a reliable, well-priced 48A charger

Avoid if

• You need Home Assistant to actively start/stop charging or set current (the official integration cannot)
• You have an older non-Wi-Fi Wall Connector

Privacy and local-control notes

The official Tesla Wall Connector integration polls the Gen 3 unit's local HTTP API over your LAN (auto-discovered), so telemetry stays local with no Tesla account required. Note it is read-only: the API exposes status and energy but no charge start/stop or current control.

Home Assistant support: supported · integration path: Tesla Wall Connector (official, local polling of the unit's on-LAN HTTP API).
