Models: Q11, Q22, Q37, Q74Compatible system: Home Assistant OS with HACS (Home Assistant Community Store) Why integrate your EV charger with Home Assistant? If you're building a smart home, integrating your EV charger with Home Assistant opens up a world of control and automation possibilities. The Ampere Point Q Series chargers are smart Wi-Fi-enabled devices compatible with the Tuya platform. This integration allows you to: - Control the charging process directly from Home Assistant,- Collect energy consumption data,- Create automation scenarios (e.g., charge only with PV surplus, during off-peak hours, etc.),- Integrate the charger with other smart home devices. If you're looking for an EV charger that works with Home Assistant without expensive commercial solutions or Zigbee/Z-Wave gateways, the Ampere Point Q Series is a great choice. 1. Current state of Tuya’s official integration with Home Assistant Home Assistant offers an official integration with the Tuya platform. However, as of May 2025, this integration does not yet support EV chargers. This means that after linking your Tuya account to Home Assistant, the charger will not be visible as a device, and you won’t have access to entities describing its status or control options. We’ve submitted a feature request to the Home Assistant and Tuya teams to expand official support for EV chargers, but until that happens, we recommend using a temporary solution: the unofficial xtend_tuya add-on. 2. Integrating Ampere Point with Home Assistant via xtend_tuya Requirements: - Home Assistant OS installed (preferably on a Raspberry Pi or NUC),- Official Tuya integration enabled (i.e., Tuya account linked and authorized),- Charger added to the Tuya or Smart Life app,- GitHub account (required for installing HACS) → https://github.com Step 1: Install HACSHACS (Home Assistant Community Store) lets you easily install community add-ons such as xtend_tuya.Installation guide: https://hacs.xyz/docs/setup/download/ Step 2: Install xtend_tuyaGo to: https://github.com/azerty9971/xtend_tuyaClick the “Open HACS repository on my HA” button.Confirm installation via the Home Assistant interface.After installation, wait a few minutes. The charger should now appear as a set of new entities. 3. What can you do after integration? Available sensors: - Charging status: e.g.,charger_free, charging, paused, error- Current charging amperage (6–48 A)- Real-time power (kW)- Energy from the last session (kWh)- Charging mode: immediate, scheduled, based on energy limit or percentage Control options: - Start/stop charging (switch)- Set charging current (e.g., 10 A instead of 16 A)- Change charging mode (e.g., charge_now, charge_schedule) With these features, you can automate EV charging to occur only during off-peak hours, with solar surplus, or based on dynamic pricing (e.g., Nord Pool, Tauron Smart). It’s also relatively easy to add additional entities for: - Current charging session (kWh)- Monthly energy usage (kWh)- Energy drawn from the grid- Energy sourced from photovoltaics ChatGPT works great as a Home Assistant consultant to help you define new variables, create automations, and troubleshoot configuration. 4. Alternative: tuya_local (local mode, cloud-free) If you prefer to stay independent from Tuya cloud servers and want a more stable connection, you can integrate your charger using tuya_local. Steps: 1. Add your charger to the Tuya or Smart Life app. 2. Install tuya_local via HACS. 3. Use the “Smart Life Cloud-assisted setup” (scan the QR code in the Tuya app). 4. Follow the configuration guide. 5. If the device or its entities don’t appear – use the TinyTuya tool to extract the required details.
