Using the pi's gpio pins?

[ivwshane]

I’m trying to wire up my pi and an 8 block relay board to use with ospi. I cannot find what gpio pins correspond to each zone.

Does anyone have a pinout that shows what gpio pins are linked to each zone?

Thanks

You get to choose which pin goes to which relay/zone. If you have already installed opensprinkler firmware onto the Pi then you can select a station (click the associated cog). In the settings popup, click the Advanced tab and select “GPIO” as the station type. You can now select the gpio pin that you want to toggle when this station needs to water. Make sure you then wire up that gpio pin to the corresponding relay. You may need to swap the Active High/Low setting in the Advanced options depending on your particular relay board.

Wow! That’s a lot easier than I anticipated! Thanks!
