Irrigation valve, Wifi + Solar. The critical feature is that it is solar powered with battery backup, so it won't fail on you or kill plants when watering on sunny days is critical. Unlike just battery-powered, it won't run out of power and hence kill your plants when scheduled watering stops on a hot day. In addition, the Wifi and SmartHome App enables you to set watering schedules from your phone, monitoring battery level, etc.
With a potted plant averaging U$50, this solar-wifi valve pays for itself when it saves your plants dying out in hot sun. Do not rely on battery-alone or wired-power valve because when power is out so is the life of each of your plant.

Advantages over competitors:

• Solar-powered, with battery-backup for 24/7 watering schedules.
• Wifi + free SmartHome App enables remote monitoring of schedules and battery charge level.
• Includes add-on coupling, for 1/2" irrigation drip tubing commonly used in USA

Water Filter	It comes with a steel water filter. If you don't have time to routinely clean the filter if your (well) water is muddy, we recommend you remove the filter and let downstream hose handle the silt instead, otherwise blockage at the filter might lead to all plants not getting water and you might not know that until days later after plants dried out. Silt in the hose is easier to flush out and any blockage might only affect the last plant on the hose run.

If no freezing inside unit (i.e. no iced up), below-0C outdoor/exterior temperature won't affect unit.
