I have a RainWave 4-zone device that works very well, but is not ‘smart’.
It does have an input for a remote moisture sensor that is supposed to prevent it from watering if the ground is still moist enough.
I was considering coming up with something where, instead of the moisture sensor, I have a wire connected to something that gets weather forecasts and status - and turns it on/off on that basis.
But then I procured, for $50, a brand-new SkyDrop controller.
After the RainWave device gives out, which these things do eventually (though this has lasted well beyond the Melnor and other single-zone controllers I’ve owned), I will get new valves and hook it up.
What I don’t get is the need for backflow prevention. My inground sprinkler lines are all auto-draining; the moment pressure in the line decreases beyond X, the auto-drain valve in the line releases and all water drains out (the valves are at the lowest point in those lines). This also has the happy effect of eliminating freeze issues, so the lines only have to be a few inches below ground.
So there is no instance where there would be pressure forcing water back into the spigot, and even in the unusual circumstance of a siphon effect there would be no water in the lines to backflow. In essence, those auto-drain valves do the job of preventing backflow.
Yet the code for the system demands a backflow preventer.
DTH means “Device Type Handler”. (DH means Device Handler.) Since not all devices are ‘SmartThings out-of-the-box capable’ of communicating directly with the SmartThings hub, a ‘Custom Code’ DTH can make such communication possible. That’s one of SmartThings advantages, apps and DTH’s that allow wider flexibility in such cases.
New to this thread and was hoping for success with this device, but not luck yet.
I was able to pair the Orbit timer with my Connect Home hub (FW 000.020.00053) but I’m not seeing any messages coming from the device. I can’t get it to respond at all using either this DTH or the power outlet handlers.
