From the EZFlora command document, “Rain Sensor (Must be pulled up to inhibit)”. How is the NC rain sensor contact connected to the EZFlora. Seems like a NO contact would be required to pull up the Rain Sensor input. The Configuration Register will show “EZFlora Inhibited” when the rain sensor is wet and connected correctly.
It sounds like the rain sensor was designed to connect between the common line going to all the valves and the EZFlora. That is the way they operate for most irrigation controllers. This does not require any additional EZFlora programming.
When the EZFlora is inhibited by the rain sensor it will not turn a Zone regardless of how asked.
The command to enable the rain sensor (not the same as the EZFlora actually being inhibited) is a Standard command.
