Domoticz

Hi,
I'm using a relay board wired to the raspberry gpio to drive some lights in my living room. As many relay boards is active low so I came here to see how to configure it and I found some crazy stuff like soldering things in the board, breaking tracks.... I knew I didn't have to touch the hardware.
I did some research in the wiring pi site, and when you export a pin (in order to use it with domoticz for example) the export creates a folder in /sys/class/gpio/gpio17/ (o the actual BCM pin you are using). Inside this folder you have a file call active_low with a written 0. You only have to change that 0 for an 1.
I updated the wiki. If there is some errors or typos, please feel free to fix it. (or if you find a more elegant way to do it, since I don't really like the "sudo sh -c" but I don't know a better way to do it)

I now this is an older post, but i have a question concerning this issue with active low relays. I have the suggested code in my domoticz.sh file, but just the other day after a power outage at my house, all the relays were energized after the Pi rebooted. Is there a way to prevent this from happening? I'm assuming that when the gpio outputs initialized that they came up active high which energized the relays. And, then when the startup file switched the configuration to outputs to active low, that the outputs never switched since no command was issued to them???? Should i toggle the outputs on bootup of the Pi to on then off to ensure that they get set properly after a reboot?

Thanks!!!
