The devices I would like to have TVheadend startup on boot are these...
WD MyBook Live (3TB)
processor : 0
cpu : APM82181
clock : 800.000008MHz
revision : 28.131 (pvr 12c4 1c83)
bogomips : 1600.00
timebase : 800000008
platform : PowerPC 44x Platform
model : amcc,apollo3g
Memory : 256 MB
Netgear WNDR3700v2 (OpenWRT)
Atheros AR7161 680 MHz

I don't know how to accomplish this but if you want to know what gave me the idea, this was it.

As for my tuner, I have an HDHomerun Connect.
