Emporia EV Charger

Quick verdict

The Emporia EV Charger is an inexpensive, capable 48A charger, but its stock Home Assistant story is cloud-based: there is no official integration, so you rely on community Emporia cloud API integrations. Its real local-first appeal is for tinkerers - the ESP-based controller can be reflashed with ESPHome for fully local control, at the cost of the normal app and some risk. Rated okay stock; excellent only if you go the ESPHome route.

Standout: A cheap, capable 48A charger whose ESP-based controller can be reflashed with ESPHome for fully local Home Assistant control.

Compatibility snapshot

Why it stands out

• Affordable 48A (11.5kW hardwired) / 40A plug-in Level 2 charger with single-amp current adjustment (6-48A)
• Built-in energy management and scheduling in the Emporia app
• Because it uses an ESP-based controller, advanced users can reflash with ESPHome for fully local HA control

Reasons to hesitate

• No official Home Assistant integration; default path is the Emporia cloud
• Community cloud integrations depend on Emporia's API staying available and unchanged
• Fully local control means flashing ESPHome - powerful, but advanced and not for everyone

Best for

• Budget-conscious buyers who want a capable 48A charger with energy monitoring
• Tinkerers willing to flash ESPHome for genuine local control

Avoid if

• You want an official, supported, local HA integration with no hacking
• You are uncomfortable relying on a vendor cloud for the stock experience

Privacy and local-control notes

Emporia has no official Home Assistant integration for its EV charger. Out of the box it relies on the Emporia cloud (the unit checks the cloud for firmware and the app/automation features run through Emporia's servers). HA users typically rely on community integrations that talk to the Emporia cloud API; some advanced users reflash the charger's ESP-based controller with ESPHome for fully local control, which voids the normal app experience and carries risk.

Home Assistant support: supported · integration path: No official charger integration; community Emporia (cloud API) integrations and an ESPHome reflash route exist.
