Hardware is ready but I am still in the middle of changing firmware to support the latching version. I would say perhaps we can start selling in a week or so. If you want you can go ahead to place an order of OpenSprinkler DC, and during checkout leave a note describing that this is for OS 3.0 Latch. We will ship as soon as it becomes ready. This way you don’t have to check from time to time when it’s going to be ready.
