Just getting going with my ST setup and looking for a small, cheap relay. I have several things that only need a momentary connection between 2 terminals to activate eg garage door, curtain closer. The only relays or switches I’ve seen are designed to switch mains level voltages and power. I only need low volt milli amp capability.
I’ve seen a couple of projects for rPi and arduino to build own, but was wondering if there is anything dedicated ready made ?
