# Editing machine class
<a name="edit-sensor-position"></a>

You can edit the machine class of a sensor from both the mobile and web apps, from either the **Asset detail** section or the **Position detail** section.

When you edit a sensor's machine class, asset condition alerts based on the updated machine class take effect from the next measurement after the update.

**Important**  
You cannot edit a sensor's machine class if it has an unresolved alert. You must resolve any alerts before editing machine class.
