So I got the TV remote modified to use on the home theater controlled iPad system. I have decided to make ALL control systems use DMX. This way both sound volumes, relays for water pumps / vacuum and other items can all be from the same Raspberry Pi running the OSC software.
Im using Touch OSC to make the interface on the wifi tablets.
I have 3 Amazon FireHD6 tablets and 3 iPads that will all have a similar but slightly customized display for each zone.
The zone will have volume, and lighting control for that area - IE: Bathroom has its own volume control and source select and light controls.
Main iPad at driver can control any zone / light in entire bus.
Video below shows the modified TV remote ($12 Amazon replacement) opened up and buttons I want to used jumped to the relay packs that get 12v from the 24ch DMX dimmer set to full off/on.
This is my poor mans way to do a Crestron control system yet doesn't cost $1000+
LED dimmer is $54
Relay boards $12 each
Remote $12 (or get a cheap universal)
Raspberry Pi $30 (runs QLC+)
ArtNet controller $99
Touch control system totals at about $225 not including your touch tablet of choice with Touch OSC app installed. (Fire tablet 6 inch is $49)
With this system there is 1 DMX universe and it can control 512 dimmers or relays just by adding the 24ch devices and relay boards.
