# EV Chargers

Configure EV chargers for energy-aware charging and automated control.

## EV Chargers

### Configuration

EV chargers are relatively easy to configure.

***

#### Energy consumed

Optional. Select one to three Home Assistant entities representing total energy consumption.

For a three-phase device, you can provide:

* one sensor for summed energy (leaving the rest empty) - it must be specified in the L1 field
* three sensors, each corresponding to one phase - L1, L2, L3.

For a single-phase device in a three-phase installation, only one field is used. It should correspond to the phase of the circuit the device is connected to.

***

#### Energy return

Optional. Select one to three Home Assistant entities representing energy exported from the charger (if applicable).

***

#### Power flow

Optional. Instantaneous power is configured in **Optional monitoring**. See [Optional monitoring](/en/unwaste-robot-configuration/optional-monitoring.md).

***

#### Control

Control configuration is identical to other devices. See [Device control](/en/unwaste-robot-configuration/device/device-control.md).

Important:

The Unwaste Robot does not guarantee vehicle charge completion by a specific time, especially that it has no control over things such as:

* Control signals mean nothing if vehicle is not connected to charger.
* Vehicle-side limits or charger firmware may override control signals. **The Unwaste Robot cannot start charging if the charger or vehicle does not allow it.**
* Vehicle could be only connected to charger when energy would be really expensive.

The best scenario is to connect vehicle just after returning and leave it connected for whole night.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.unwaste.energy/en/unwaste-robot-configuration/device/ev-chargers.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
