Tesla is a US company best known for electric vehicles that also sells home energy products: the Powerwall home battery with its Gateway, solar, and the Wall Connector EV charger. These energy products are managed through the Tesla app, and outside developers can reach them through Tesla's Fleet API or paid services built on it. This page covers the home energy side; vehicle integrations are mentioned only briefly.
Powerwall connects through its Gateway, which can use Wi-Fi, wired Ethernet or cellular, and Tesla says the app's remote monitoring depends on that connection. Home Assistant and openHAB can also read the Powerwall Gateway over the local network, while the Fleet API and Teslemetry reach Tesla's cloud. The Wall Connector is documented for Home Assistant as a Wi-Fi charger with a local interface.
That suits owners who want battery, solar and charger data inside Home Assistant or similar, locally or through Tesla's official API. It is weaker for voice assistants and ecosystem apps: we found no Tesla page for Alexa, Google Home, Apple Home or Matter on the energy side, and the Powerwall 3 local interface is more limited in Home Assistant than the Powerwall 2.

Vehicles Covered by the same app and API; not the focus of this page
The single official app for vehicles and energy products. The App Store listing describes Powerwall monitoring, including stored solar energy, home consumption and grid export, and downloadable solar and battery data, and says Powerwall features require Powerwall 2. We could not confirm from the listing that it controls the Wall Connector, and could not confirm Powerwall 3 support from that page. Tesla's support page says energy products must be installed and powered on before they appear. Published by Tesla, Inc.; iPhone needs iOS 17 or later. The Android link comes from Tesla's own support page.

What it means
Sources
Connection
Wi-Fi
Yes
Tesla's Powerwall connectivity page lists Wi-Fi 802.11 b/g/n. Gateway 1 is 2.4 GHz only and Gateway 2 supports 2.4 and 5 GHz, and captive portals and enterprise security are not supported. The Powerwall 3 datasheet lists 2.4 and 5 GHz. Home Assistant documents the Gen 3 Wall Connector as a Wi-Fi model.
Wired Ethernet is described as generally the best performing option for Powerwall, and the installer sets it up inside the Gateway. The Powerwall 3 datasheet lists Ethernet. We could not confirm Ethernet for the Wall Connector from the pages we read.
Powerwall can connect over cellular when service is available, meant as a backup when no other connection is configured. Gateway 1 loses cellular as carriers retire 3G. The Powerwall 3 datasheet lists LTE/4G and says cellular should not be the primary connection.
None of these are described for Powerwall or the Wall Connector on the pages we read. The Powerwall 3 datasheet mentions CAN between the Gateway 3 and Backup Switch and RS-485 for meters, which are internal links rather than smart home radios.
We found no Tesla page, and no mention on the Home Assistant or Teslemetry pages, about Matter for Powerwall or the Wall Connector. We could not confirm either way.
Tesla does not document Apple Home for energy products on the pages we read. Teslemetry lists Homebridge among the integrations it supports, which points to a community route. We did not open the Homebridge plugin itself.
No SmartThings integration for Tesla energy products was found. We could not confirm either way.

Tesla app (remote monitoring)
Official
Remote monitoring of Powerwall through the Tesla app needs an internet connection. Without one, Powerwall keeps running in its last operating mode and still provides backup power, but remote monitoring and over-the-air updates are not available.
Four built-in integrations apply, none maintained by Tesla. Powerwall is local polling against the Gateway IP address, with a password taken from the Gateway label or serial number; it supports Powerwall 2 and Powerwall 3 with limits, and not Powerwall 1. Powerwall 3 lacks off-grid operation, backup reserve and per-battery sensors there. Tesla Wall Connector is local polling every 30 seconds for the Gen 3 Wi-Fi model. Tesla Fleet and Teslemetry are cloud polling; Teslemetry needs a paid subscription and also covers vehicles.
Third-party apps, none published by Athom as far as we could confirm. Tesla Energy by Diederik Bakker covers the Powerwall Gateway over the LAN and its listing notes a Homey Bridge is required; it was last updated about three years ago. Tesla Power Connect by Rune Vaernes covers the Gen 3 Wall Connector, monitors only, and also needs a Homey Bridge. Teslemetry's own Homey app is cloud based, needs a Teslemetry subscription and a Homey Bridge, and covers Powerwall, solar, Wall Connector and vehicles. All list Homey Cloud, Pro and Self-Hosted Server.
A TeslaPowerwall binding is in openHAB's add-on list. It supports Powerwall 2 only, connects locally with the Gateway address plus the email and password of the local account, and has no auto-discovery. It is not maintained by Tesla.

Teslemetry
Community
A third-party service that exposes the Tesla Fleet API, Fleet Telemetry, webhooks and server-sent events. It supports vehicles, Powerwall, solar and Wall Connector, offers a 7-day free trial, and lists Home Assistant, Homey, Homebridge, Node-RED and n8n among its integrations. The page does not say who operates it or give prices.
Tesla's developer documentation lists energy endpoints for live site status, site settings, backup reserve, operating mode and Wall Connector live charging status, plus history, storm mode and tariff settings. The page we read has no authentication or pricing details. Evcc's documentation describes the Fleet API as official but paid, with a $10 monthly credit for private users, which we did not confirm on a Tesla page.
Home Assistant and openHAB read the Powerwall Gateway locally, and Home Assistant reads the Gen 3 Wall Connector locally. We found no Tesla page documenting these local interfaces as supported developer APIs.
Checked 11 November 2026 against the brand's own pages, app store listings and each project's own page. “Not found” means we searched and found nothing, not that it is impossible. Compatibility changes often. Spot an error? Tell us and we will fix it.
