Like many things in Home Assistant, there are a few different ways to utilize the features of the Inovelli switches. For example, this article will discuss one way of doing scenes, but you may want to use the community created blueprint if that is more what you are looking for: homeassistant-config/blueprints/automation/rohankapoorcom/inovelli-vzm31-sn-blue-series-switch.yaml at master · rohankapoorcom/homeassistant-config (github.com). You can skip the blueprint, and continue below for another method of utilizing scenes.
First, it is important to go to the switch that you are trying to setup the automation on and use the button combination that you are wanting to setup in the automation. For example, if you are going to use the 2X Tap Up scene, then physically go to the switch and tap the up button 2 times. You might want to take this opportunity to perform several of the commonly used button scene combinations. Click the up button 2x, the down button 2x, the config button 2x, etc. This will load the scene information into Home Assistant.
Next, you should be able to go into Home Assistant -> Automations and create a new automation.
On the popup, click on "Create new automation".
On the next screen choose "+ ADD TRIGGER" and select the "Device" option.
On the following screen choose the button combination that you wish to activate the automation.
Note: if the particular button combo is not there, please see the beginning of the guide on how to physically press the button combo at the switch to populate it here in this dropdown. At this point if you physically press the button, you might have to start the "create automation" part over to get it to fill in the drop down.
Now, you should be able to finish the automation by setting up and conditions and actions!
