That is an excellent result.

Using multiple controllers is a very good solution to spreading the heat, and it also provides some redundancy if you ever need to work on part of the system.

It may not end up being all that much cheaper than a Chinese magic mystery box, but at least you will be able to repair it, and fine tune the software to do exactly what you want. Plus there is the satisfaction of doing it all yourself.
