Creating a simple HMI

In this tutorial, we will demonstrate, how to create a HMI (human-machine interface). The HMI is graphical interface displayed on the touchpanels or in web browser, which allows to show the status of the automation process and to control it. In this tutorial we will focus on the built-in HMI capabilities of Mervis, which runs on the UniPi controller and is accessible via web browser.

The goal is to display current temperature in the room, set the threshold temperature a display if the heating is ON or OFF.

• UniPi controller running Mervis OS
• Temperature requlator project from previous tutorial
• 24V power supply
• 1-Wire temperature sensor

In this tutorial, we will use Unipi Neuron L503.
