Ebay is full of 24v to 5v controlers I want to use opensprinkler down the road right now I use relaysright now . I want to also use it for garage door opener so it seems nice to have one power source and connect to 24 power supply and use it with garage door relays. Does anyone have experience with down conventer ?
I don’t think you need an external 24VAC to 5VDC converter: OpenSprinkler has a built-in switching regulator that does the 24VAC to 5VDC conversion. The 5V output is accessible from the VIN pin (in the pinout area).
