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).

Buying reality check

Price notes: Model: Gen 3 Wall Connector, 24 ft cable. Tesla's own retail price is $535 (shop.tesla.com, re-read 2026-09-08). The Amazon buy box read $750 on 2026-09-08 and $735 on 2026-08-28, about 40% above Tesla's price, so preferDirect is set and the Tesla store is the primary buy surface. Quote the $535 figure, not the Amazon one. CAVEAT ON THE DIRECT LINK, read 2026-09-08: shop.tesla.com states 'Tesla ownership is required while supplies are limited' and renders 'Sign in to add to cart' in place of an add-to-cart button, so the primary buy surface is purchase-gated for non-owners and the Amazon listing is the only open channel. OWNER CALL: whether preferDirect should stay set given that gate - it is a revenue-affecting link change, so it was left as is and the three article surfaces now state the gate instead. Note this is the NACS connector: a J1772 car needs an adapter, or Tesla's separate Universal Wall Connector, which has one built in.
