Home Assistant can connect EV charging with the rest of your smart home. Ampere Point Q Series owners can now do this more easily with TuyaExtend AmperePoint: an open-source integration and a ready-to-use dashboard designed specifically for EV charging.
One screen shows live power and energy, lets you set the current limit, select a charging mode and create a weekly plan. The dashboard works on desktop and mobile, while HACS handles installation and update notifications.
Update to our 2025 guide: Xtend Tuya can still be used as an optional entity source, but it is no longer required. In the simplest setup, TuyaExtend AmperePoint works directly with Home Assistant’s official Tuya integration.
What does TuyaExtend AmperePoint add?
The official Tuya integration may detect the charger without creating individual Home Assistant entities for every available data point. TuyaExtend AmperePoint reads the charger’s available runtime data from the Tuya layer, normalises it and presents it in a format that makes sense to an EV owner.
Depending on the product generation, model and firmware, the integration can expose:
- connection and charging status,
- session start and stop control,
- live charging power,
- current-session and last-session energy,
- total energy when reported by the charger,
- charging-current control,
- charging mode and target energy,
- temperature, faults and diagnostic information,
- phase measurements when the charger reports plausible data,
- a raw Tuya DP view showing which values are writable.
A missing data point does not break the interface. Sections that are unsupported or temporarily unavailable are simply hidden.
An EV-focused Home Assistant dashboard
Instead of browsing a long list of technical entities, you get a dedicated Ampere Point panel. Live charging power is the main value on screen. Session control, current limit, charging mode and target energy sit next to it, followed by measurements, device status, diagnostics and the full DP table.
The layout is responsive: it uses the available width on a desktop and switches to a clear single-column view on a phone. Each charger can have its own panel in the Home Assistant sidebar.
A minute-accurate charging planner
The built-in planner goes beyond the single timer window stored in the charger. You can create multiple time intervals, assign them to selected weekdays and set a different current limit for each interval.
The planner supports:
- multiple intervals and weekdays,
- minute-accurate start and end times,
- a separate current limit for each interval,
- manual charging for 30 or 60 minutes,
- adding a selected amount of energy in kWh,
- pausing until the next scheduled interval,
- returning to the weekly plan at any time,
- a preview of the next effective action.
Home Assistant sends commands in a controlled sequence: it sets the mode and current limit before issuing start or stop. The dashboard shows whether the command is waiting for confirmation, has been confirmed by Tuya or has failed. The saved plan and any manual override are restored after Home Assistant restarts.
Three ways to control charging
Charge now
The straightforward option for starting a session manually. Select the current limit and decide when charging should stop.
Charge to an energy target
Choose how much energy the charger should deliver. Availability and reporting behaviour depend on the charger variant and firmware.
Scheduled charging
Use the schedule supported by the charger or the more flexible Home Assistant planner. The latter adds multiple weekly windows, manual overrides and a clear preview of the next action.
How to install the integration
- Add the charger to the Tuya Smart or Smart Life app.
- Configure Home Assistant’s official Tuya integration and authorise your account.
- In HACS, add
https://github.com/amperepoint/tuyaextend-amperepointas a custom repository in the Integration category. - Download TuyaExtend AmperePoint and restart Home Assistant.
- Open Settings → Devices & services → Add integration, search for “TuyaExtend AmperePoint” and select the detected charger.
- Keep the dashboard option enabled to add the ready-made panel to the sidebar.
The full installation manual, diagnostics and source code are available in the TuyaExtend AmperePoint GitHub repository. The project is open source.
What if you have several chargers?
Each device is configured as a separate integration entry and receives its own entities. You can create an individual dashboard for every charger or place several Ampere Point cards on one Home Assistant dashboard — useful for a two-EV household, a small company or a shared garage.
How do updates work?
HACS monitors integration releases and notifies you when a new version is available. A Home Assistant restart may be required after downloading an update. The dashboard footer also shows the installed version and its update status.
What is coming next?
TuyaExtend AmperePoint is under active development. The roadmap includes:
- full local operation — direct LAN communication, automatic IP discovery and a simpler authorisation flow,
- dynamic energy prices — direct support for tariffs, including services such as Pstryk and generic Home Assistant price entities,
- easier solar integration — charging from PV surplus using energy data already available in Home Assistant.
These are planned features and are not part of the current stable release. Advanced users can already use entities supplied by tuya-local or LocalTuya as an alternative source, but the official Tuya integration remains the recommended and simplest installation path today.
Home Assistant for EV drivers — without building a dashboard from scratch
TuyaExtend AmperePoint combines detailed charger data, controls and a weekly planner in one interface. Start with the ready-made dashboard, then connect charging to your own automations, energy tariff, solar installation or whole-home power management.

Note: available data and commands depend on the charger model, product generation, firmware and the data exposed by Tuya. A current limit selected in Home Assistant does not replace a correctly designed electrical installation, suitable protection or the manufacturer’s safety guidance.
