Select Digital Input or Pulse Counter.

GPIO1/2

Digital input: detect the real state of valve to know if valve control takes

Acquisition Type effect.

Pulse counter: connect water meter to measure the flow.

Prevent Jitter Delay Time

The device will not upload GPIO status during this time to avoid frequent uplinks. This only works when GPIO mode is DI and also applies to both GPIO interfaces.

Select the contents to report to network server.

All: Report all interface status;

Data Reporting

Valve 1 & Water Meter 1: Report the status of the Valve 1 interface and data of GPIO1;

Valve 2 & Water Meter 2: Report the status of the Valve 2 interface and

data of GPIO2.

Power Supply State or off according to this parameter. Working mode of LoRaWAN® device.

UC511: Class A, Class B and Class C, Class C to B are available;

UC512: Class A and Class B are available.

Class Type

Note: for Class B mode, if the device does not receive beacons for more

than 30 minutes, it will switch to Class A mode automatically; for Class C

to B mode, if the device does not receive beacons for more than 30

minutes, it will switch to Class C mode automatically.

When the device works under Class A mode, it only receives control

commands every reporting interval comes. In order to shorten the delay

Response Time time of control, the device will send blank package to allow to receive the

control commands every Response Time interval.

Note: The shorter the response time, the shorter the battery life.

Ping Slot

Description It supports adding 16 plans at most. Enable or disable this plan.
Control the solenoid to open or close the valve during the plan.
Set the time range to execute this plan.
Set the amount of water flow through the valve during this plan, 0 means this condition will not work. Note: 1) Either time or water volume reaches the condition, the plan is completed and will stop executing. 2) When the GPIO type is not pulse counter, this condition will not work. Set the regularly weekly schedule to execute this plan. If none is selected, the plan will only execute once.
