Ok, for anyone else having issues like me, I have found the solution and I can now see all 4 gangs of my MCOHome device.
-
I went to Community Device Drivers (AKA Compatible Devices Wiki) and went to MCOHome, and downloaded both the "Driver for Triple" and added this as stated in the post.
-
Went to the "Driver for Triple" and went to line 225 and found "for (i in 1..3) {" and changed the 3 to 4.
-
I went to devices and clicked on recreate children.
-
Bam it works!
I hope this helps someone who is having the same issue as me!
