Hi Mans,
There are no conditional triggers currently built into Engen. If I understand correctly, Engen development is currently on hold due to low sales or low interest in the product. The current build is stable and works great, so hopefully this will change in the future.
In the meantime, there are a couple of third party solutions that could achieve what you are asking. I have not used these yet, just looking into them as options:.
Domoticz
Home Assistant
Both could potentially work in conjunction with Engen using the Engen command line interface or webserver, or be set up as a stand alone solution.
Hope this helps!
