# Additional readings

Add custom readings to monitor additional energy and power measurements.

## Additional readings

## What Are Additional Readings

**Additional readings** let you attach extra Home Assistant sensors to a circuit, production source, storage, or device.

Each entry has:

* a **Name** (your label for this reading),
* a **Type** (determines which sensor field is shown),
* the corresponding **Home Assistant entity**.

Additional readings appear in graphs and statistics when configured. They can also have [Monitoring alerts](/en/unwaste-robot-configuration/optional-monitoring/monitoring-alerts.md).

Additional readings are configured inside the **Optional monitoring** section on each element form. See [Optional monitoring](/en/unwaste-robot-configuration/optional-monitoring.md) for where to find this section.

## Supported Types

When you add an additional reading, you choose a type. Available types include:

* **Energy** (single-phase or three-phase)
* **Power**
* **Reactive power**
* **Voltage**
* **Current**
* **Temperature**
* **Irradiance**
* **Heat produced**
* **Battery**
* **Power factor**
* **Reactive energy** (three-phase)

The form shows entity selectors matching the selected type.

## Common Examples

### Irradiance (solar installations)

If you have a pyranometer or similar sensor, add an additional reading of type **Irradiance**.

The system can display a sunlight chart. This is for reference only and does not affect control decisions.

This replaces configuring irradiance as a separate top-level field on the inverter form.

### Temperature

Add a reading of type **Temperature** to monitor ambient, buffer, or panel temperature alongside energy data.

***

## Monitoring Alerts

Each additional reading has its own **Monitoring alerts** button. See [Monitoring alerts](/en/unwaste-robot-configuration/optional-monitoring/monitoring-alerts.md).

# 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/optional-monitoring/additional-readings.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.
