# HA: Sensor vervangen

Heeft u al een bestaande sensor in HA en wilt u de historie hiervan bewaren bij het aansluiten van de nieuwe waterlezer dan volgt hieronder een tip van een van de gebruikers (Rik).

* Schrijf de sensor id’s op van de sensors die vervangen worden
* Verwijder oude sensor
* Herstart HA
* Vervang de id's van de nieuwe sensor met de id's van de oude (opgeschreven bij eerste actie).

Resultaat

* historie blijft bewaard
* sensor historie vanaf het moment dat de nieuwe sensor is gekoppeld
* grafieken en tabellen op basis van oude sensor id's blijven bestaan

## 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.smart-stuff.nl/dsmr-api/koppelingen/ha-sensor-vervangen.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.
