It's going well. I think the last item I have is the UPS. I used https://help.ubuntu.com/community/apcupsd and eventually got everything working so I can see the status of the UPS but (I'll admit it may simply be me failing to understand the instructions) I don't see how to control the 'Master Socket' behaviour. The UPS has a socket which the PC is plugged in to and controls the supply to several other sockets, so peripheral devices have their power supply managed by the demand from the PC. There is some mention of Master but it looks like when you have multiple UPS devices. If I turn off the PC the peripherals lose power after a delay, then get power back when I turn the PC on. Can I control that with apcupsd?
