Setting Up the Set Value Widget

To get started, add the Set Value Widget to your dashboard. This widget allows you to set values manually, making it ideal for applications where you need to adjust device settings on demand.

What should you configure?

• Title: In the Basics section, you can customise the title of your widget. This could be specific to the function you’ll be controlling, such as "Set Target Temperature" or "Set Driver," to make it clear what the widget is for.

Pro tip: You can add a Value Widget next to the Set Value Widget. That will allow you control the value that was set via the Set Value Widget.

• Data Source: Under the Data section, select the device and the field that you want to control. This selection enables you to target exactly the value that needs updating, giving you precise control over the device’s settings from the dashboard.

• The Appearance tab offers color customisation, allowing you to change the widget’s color scheme.

Using the Reset Feature

The SOS widget includes a reset function, allowing users to deactivate the alarm directly from the dashboard. This feature is ideal for managing alerts and ensuring that alarms return to a default state after being addressed.

Practical Use Cases

1. Temperature and Environment Control: In environmental applications, the Set Value Widget can be used to set target temperatures, humidity levels, or other environmental conditions for devices like climate controllers, HVAC systems, or smart thermostats.

2. Threshold Adjustments: Use the widget to update operational thresholds for monitoring systems. For example, in an industrial setting, it could adjust the threshold for alerts related to machinery performance, such as vibration or temperature limits.

3. Irrigation or Resource Management: In agriculture, the widget could control irrigation systems by setting watering intervals or duration, allowing precise management of resource allocation based on crop needs.

4. Lighting and Energy Management: The widget can be used in building management to set lighting intensity levels or energy-saving thresholds, enabling quick adjustments to optimize energy use.
