# Multi System
It may happen that you have multiple systems (home, office, vacation home, etc.) and therefore want to access each of them quickly. This guide explains how to proceed.
If you are logged into only one system, from the main screen you need to click on •••, then select the **Systems** option.
On the Systems page, click on •••, then choose the **Add System** option.
Enter the credentials for the new system and press **Log In**.
The app will automatically connect to the new system. To switch systems, simply click on the specific box.
Once you have logged into more than one system, a house icon will appear in the main screen, allowing you to quickly switch between systems.

## 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.ohmautomation.io/en/android/guide/systems.md?ask=&goal=
```
`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.
