# Home

"Home" is a a default start page after connection to the gateway. 

Click on “Home” if you want to return to it from another part of BBO web GUI.

On this page you can see the summary of all the sensors and interfaces (called devices) connected to the gateway.

&#x20;The upper part presents the number of 1-Wire devices.

**Devices connected**—the number of 1-Wire devices connected to the BBO.

**Loop time**—the time, in seconds, it takes for the BBO to cycle through polling all the devices and receive a response. As more devices are added, each individual device gets read less frequently since only a single device can be read at a time. This value is useful for determining how frequently each sensor gets read.

**Device poll count**—the number of times the BBO has polled devices. The rate of polling depends upon the number of devices and the specific device. Some 1- Wire devices refresh every second while others may do so much faster (e.g., The DS18B20 causes a 900ms delay while waiting for the temperature to be converted, whereas the DS2406 has no delay).

**Supply Voltag**e—the voltage being supplied to the BBO.

**Channel Chart**—displays parameters specific to each channel.

·         Devices—number of devices on each channel

·         Errors—number of errors on the 1-Wire bus for each channel since the last reset

·         Voltage—voltage of each channel

**English/Metric** - switches between Fahrenheit and Celsius degrees.&#x20;

The middle part shows the devices connected.

# 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://help.boomerang3.com/bbo-gateway-installation-manual/bbo-web-interface/home.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.
