timekiller Posted May 13, 2016 Posted May 13, 2016 Ok, so here is the situation- I built an arcade that uses a PC to run various emulators. I have a 6 button keypad and I want to use one of the buttons to SAFELY shutdown the PC and kill power to the rest of the arcade. I figure I can use a garage door opener (Insteon 74551) to accomplish this. The plan is to connect the button to the power button on the PC (momentary push is perfect for this) and the status to determine when the PC is off (relay hooked to a 5v power connector. When the PC is on, the relay trips, connecting the status wires). I should also mention I have the whole arcade plugged into an Insteon outlet. Actually, it's a surge protector plugged into the outlet. Then the PC and other things (lights, etc) plugged into the surge protector. Here is the logic I am trying to create: If outlet is ON and keypad button is pushed then turn on outlet momentary push garage relay (turns on PC) If outlet is ON and keypad button is pushed then momentary push garage relay (sends power off signal to PC) wait for garage sensor to report OFF (happens when PC completes power down) then turn outlet OFF Ideally, the light in the keypad button should reflect the state of things I figure this probably can't be done with a single program or scene. I just have no idea how to accomplish everything. Any help would be much appreciated.
oberkc Posted May 13, 2016 Posted May 13, 2016 A few quick thoughts: Keypad buttons in their default state will toggle between ON and OFF. There is typically no logical statement that is equivalent to "keypad button is pushed". One can put the button into a state where each push is ON or where each push is always OFF. In such a state, the program would then look for the ON or OFF command, as configured. Furthermore, you might actually be able to do this in a single program. ISY has THEN and ELSE paths. In the logical form, it might be something like: if keypad button is pressed ON (keypad button configured to always send ON commands) and status outlet is off then turn on outlet push relay else push relay wait xx amount of time turn off outlet turn off keypad button I suspect, however, that you will want to add further stuff which could drive you to multiple programs. Things always get more complicated after you try things out and come up with new requirements. Also, if it is imperative to wait for direct feedback from the computer being off, this will likely drive you to a second program.
timekiller Posted May 13, 2016 Author Posted May 13, 2016 Thanks for the advice, I came up with something different. Here it is: Configured the grarage opener and keypad just like it was an actual garage door, as instructed here: http://homeautomationguru.com/insteon-enabled-your-garage-doors/ Except, obviously the relay is the PC power button and the sensor is hooked to a relay on a power molex in the PC (sensor is "off" when PC is off) Then I made 2 programs: Program 1 "PC Power ON" ----- If Status Arcade Outlet is Off and Status Keypad button ON then Set Arcade Outlet ON Set garage relay 3 (Beep Duration) ------ This detects the state change of the keypad button and turns the outlet on, then holds the PC power button for 3 seconds (long enough for power to get to the PC and power it up) Program 2 "PC Power OFF" ----- If Status Arcade Outlet is ON and Status Keypad button is OFF and Status garage sensor is OFF then Set Arcade Outlet OFF ----- This detects that the PC is off (sensor), the keypad is off, and the outlet is on and simply turns the outlet off. That's it. All my criteria are met here. The Keypad button basically acts like a PC power light. If the PC is on, the button is lit. If the PC is off, the button is not lit. Pushing the button powers everything up and safely shuts everything down. I like it If anyone is interested, this is the arcade I built: http://imgur.com/a/eOurd It emulates all classic arcade games, NES, SNES, N64, Sega Master System, Sega Genesis, Playstation, Laser Disc Games, Wii and a few others. There is also a Wii-U and PS3 console in the control panel.
oberkc Posted May 13, 2016 Posted May 13, 2016 I like it, too. Personally, I probably would not include the first two conditions of the second program, but I am funny about such things.

I didn't want a race condition where amd turning it on and the sensor does not register the PC on yet and it shuts the whole thing down.
