# Link nodes with the WIN gateway

1\.       In WIN gateway web panel, go to System Configuration -> Devices.

2\.       Power on the WIN node. It shall start quickly blinking the internal LED which indicates it is advertising over radio and is discoverable by any gateways nearby.

3\.       After approx. 20 seconds the node shall appear in “Unlinked Devices”. If the node is not shown, check the possible solutions in chapter 7.

4\.       Click the unlinked node row and then OK to link it to the gateway.

5\.       It takes about 20 seconds to 60 seconds to link a node. After successful linking the node shall appear in “Linked Devices”. Measurements made by the node will now be transmitted to Boomerang 3 with default transmission interval of 1 minute.

6\.       In Boomerang 3, the nodes’ sensors should appear under “Uninstalled Measuring Points”. Please check [A-B3 Domain Administrator Manual](https://help.boomerang3.com/boomerang-3-domain-administrator-manual/) for details.

&#x20;Please note that after the gateway restart the “Devices” list is always empty. The device (node) is added to the list after it communicates with the gateway.

If a node has run out of batteries or is too far from the gateway to communicate, it will not appear on the “Devices” list.

**It is very important to not leave the battery powered WIN node unlinked. In this state the node uses a lot of power which will drain battery very quickly.**

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/win-gateway-installation-manual/quick-installation/link-nodes-with-the-win-gateway.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.
