This unit requires one (1) batter, 9-volt, and is easy to install. I've had the unit for about 2 weeks so I'm not sure how long the battery lasts. No problems so far!
All controlled by bluetooth using an application available for iOS or Android. There is no manual interface (buttons, switches, etc) for this tap controller. From the app you can manually turn the tap on/off, set a schedule, etc. I use it for my oscillating sprinkler because I don't have to mess with going out there and turning it off/on every day and trying to get the tap adjusted to the desired water flow.
This model has: Inlet: 3/4” standard hose faucet Outlet: 3/4” standard hose pipe thread.
Approximately 32 feet (10m). You may get longer or shorter distance depending on the interference in the area.
Dear Sandy, This device operates with a phone app which will give a broad selection of options one of which is to remotely manually turn the faucet off and on. Additionally, it allows for a number of specific start and run times if desired. I've used mine successfully for the past year and been very pleased with it. I hope this helps you with a decision on your project. Sincerely, hamrdul
