Can I test LawnCheck before buying a controller?

Yes. You can create an account and set up your schedule before you buy a controller. After you are satisified that LawnCheck meets your needs, you can then obtain a controller. Setting up the controller to connect to your schedule is easy.

How does the LawnCheck web site communicate with the controller?

The EtherRain controller communicates with the LawnCheck website as an HTTP browser keeping your network secure as no additional router ports need to be opened. For reliable results, the controller should be connected to the Internet through a gateway/router using an always-on connection (typically DSL or Cable Internet). The controller keeps in contact with the LawnCheck website automatically and continuously. Bandwidth usage is negligible.

How do I connect up the EtherRain controller to my sprinkler valves?

The valve wires are attached to the EtherRain controller just like they are with a standard timer box. The valve connection process is the same.

What if it is raining? Will the EtherRain controller stop irrigation when it is raining?

LawnCheck provides weather dependent irrigation capability using real time weather data. Weather data forecasts are provided by location code (Yahoo! Weather) or local weather station (Weather Underground). You can setup your programs to stop watering if the weather forecast indicates precipitation at the time that a cycle starts, or, if you use a weather station that has a rain gauge, when the rain gauge exceeds a threshold. Also, the EtherRain controller has a rain sensor input and offers a very low cost rain sensor that will also stop irrigation during locally occurring precipitation events.

How reliable is this method of irrigation?

LawnCheck is as reliable as your Internet service. Today the major Internet service providers offer very high reliability, more than enough for yard irrigation. LawnCheck provides connectivity monitoring reports and email alerts so you always know the status of your irrigation system.
