I have a Controllino MAXI Automation connected to Cayenne MQTT and it works great so far.
I use it to open and close 5 different Garage ports (Crawford port)
Now I want to program a relay switch that connects 3 cables at the same time.
On my Controllino is all R0 - R9 used now for other function.
So i Also need to use/readress the digital outputs (D0, D1, D2, etc)
It should be Potential Free (No V on the outputs)
If i can solve this then i can change the ON/OFF settings for automatic closing on the garage door.
