Where is the mini-relay?

I’d like to make use of the mini-relay on my open-sprinkler pi, but I have no idea where the pins are physically located! Can someone point me in the right direction?

The mini-relay has been removed from the circuit a while back (probably more than a year back). If you want to use a relay, you can get a 24VAC relay and connect it to any zone like a sprinkler valve. We have tested several 24VAC relays that work fine with OpenSprinkler:

Also, if you are looking to control powerline devices, you can use an RF transmitter in conjunction with RF power sockets. RF station is now a standard feature in OpenSprinkler firmware, and OSPi circuit board has pin headers that you can directly plug a RF transmitter into. This feature is explained in this blog post:

Thank you for the update. I guess I’ll go with my own relay board through GPIO.
