# Restart device

Restart the device, causing it to power cycle, and initiate a new join procedure.

{% hint style="danger" %}
Using this command will effectively disconnect the connected appliance for a brief period.
{% endhint %}

**Example downlink**: 0xA5

{% hint style="info" %}
The following mechanic only applies for devices with firmware version ≥ 1.2.
{% endhint %}

If the command is sent via an **unconfirmed downlink**, the device starts a 20-second delay period, after which it restarts.

If the command is sent via a **confirmed downlink**, the device transmits an acknowledgment uplink, then starts the 20 second delay period, after which it restarts.

## 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.mclimate.eu/mclimate-lorawan-devices/devices/mclimate-16a-dry-switch-16ads/mclimate-16ads-device-communication-protocol/restart-device.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.
