# Manual input

In the configuration overview of the fields, you can manually enter measured values for the following fields:

* Integer
* Float
* String
* Boolean

{% hint style="info" %}
If your devices get regularly data, the incoming data will replace your manual input. Take into consideration that any manual input will be saved in the database for as long as the data retention period covers, afterwards all values will get deleted, unless you setup a role.
{% endhint %}

Simply move your mouse cursor over the drop-down selector of your respective field and click on the "Set Value" item:

You will see the following Modal / View:

Now enter the desired measured value into the field and confirm it by clicking the "Set Value" button. Your measured value is now entered with a time stamp.

## Manual Input triggers API

If you enter a measured value into the field in this way, it is passed on internally to the API via the backend and this measured value is also output automatically via MQTT.

If you have created rules that monitor the measuring field, then these rules are now also informed about the entry.
