I’m a proud owner of an OpenSprinkler DC (v 2.3) and I’m trying to figure out exactly what type of connector (jack, plug, etc.) has to be used in order to use the secondary power input.
Has anyone determined the type or the diameter of this connector? I tough they were “standard” but I’m finding a lot of troubles in buying the right one.
This is a standard power plug (2.1mm internal diameter, 5.5mm outer diameter), center positive, side negative. If you have any spare DC power adapter that you don’t need, chances are it has this exact power plug. You can also buy it as a separate component: https://www.amazon.com/SIM-NAT-Pigtails-Security-Application/dp/B01GPL8MVG
