A little background

I used to sell a TON of global cache products for my business, we had kids rooms in many projects  that we wanted an inexpensive solution to bring into the system.

The global cache gc-100 and the ip2ir line did that nicely, but now we do centralized HDMI distribution, so there is no source equipment that needs to be controlled, and the last time I sold a non IP controllable TV was 4 years ago....

So now that I have both unsold stock, and also lots of reclaimed products that were destined for the trash, I really want to use them.

The important parts that *I* care about them in this scenario is that the GC-100-12 has 3 relays, and 6 IR ports, but those IR ports are TRS jacks, and support a contact input on the ring.

Thus this monstrosity was born, it consists of 2 gc-100-12 cases each with a Global Cache IP2IR (3 ir outputs/contacts) 

Advantages:

It's built

I know they work, and they are built well.

It supports notifications in the API on contact state changes

its free! (for me)

Using products instead of trashing them

Disadvantages:

This solution requires setting/using 4 ip addresses and each device has to have a connection maintained.
