Rule Examples/en: различия между версиями

In the example, the motion sensor is connected to the "dry contact" input, control type "switch". The siren is connected to the built-in Wiren Board relay, and the lamp is connected to the relay box via Modbus. When the "dry contact" input (motion sensor output) is closed, "1" is supplied to the lamp and the relay, and "0" when it is off.

The rule is triggered every time the control value "D1_IN" of the device "wb-gpio" is changed. The new value of this control is passed to the rule code as a variable newValue.

dev["wb-gpio"]["Relay_2"] = newValue;

dev["wb-mrm2_6"]["Relay 1"] = newValue;

dev["wb-gpio"]["Relay_2"] = newValue;

dev["wb-mrm2_6"]["Relay 1"] = newValue;

A motion detector with a "dry contact" output is connected to input D2. When motion is detected, it shorts D2 and GND and status "1" appears on the corresponding <code>wb-gpio/D2_IN</code> channel.

* when movement appears, the light turns on. If a thirty-second "off" timer was previously started, this timer is disabled;

* when motion is lost, a thirty second "off" timer is started. If he manages to reach the end, the light turns off.

When connecting the WB-MSW v.3 sensor to the Wiren Board controller, it is possible to create interesting scenarios using data from the sensor. For example, turn on the light when moving, signal with LEDs when the CO2 or VOC value is exceeded, turn on the air conditioner if it is hot or the air humidifier if the air is too dry. Rules are created individually for tasks. Here we will give some examples to understand the principle of working with the sensor. More examples of writing rules can be found in the '''[[Движок правил wb-rules]]''' documentation.

             dev["power_status"]["Vin"] = dev["wb-adc"]["Vin"] ;

     return  dev["wb-adc"]["Vin"] > dev["wb-adc"]["BAT"];

     dev["power_status"]["working on battery"] = false;

For example, we want the lighting to be on from 10 to 17h. The libschedule will follow the "turn on the lights" rule once a minute from 10 am to 17 PM.
