RF Switch

Supports basic 433MHz AM transmitter attached to a GPIO pin via 5v buffer. You may be able to get away with connecting the GPIO directly and running from 3.3v, but timing and performance won’t be as good.

Uses hardware timer to generate PWM output using interrupts.

Developed for use with i-Lumos lightswitches which use a 24-bit code. Timing parameters are programmable though so may work with other devices.

class Controller : public IO::Controller

#include <Controller.h>

Controller for 433MHz transmitter.

Protocol is flexible but tested only with i-Lumos light switches. Written specifically for ESP8266 and uses the hardware timer to generate PWM signal via interrupts.

Public Functions

inline virtual const FlashString &classname() const override: Get the class name for this Controller.

virtual void handleEvent(IO::Request *request, Event event) override: Implementations override this method to process events as they pass through the stack.

struct Timing

#include <Device.h>

Protocol timings in microseconds.

Public Members

uint16_t starth: Width of start High pulse.

uint16_t startl: Width of start Low pulse.

uint16_t period: Bit period.

uint16_t bit0: Width of a ‘0’ high pulse.

uint16_t bit1: Width of a ‘1’ high pulse.

uint16_t gap: Gap after final bit before repeating.

class Device : public IO::Device

#include <Device.h>

Public Functions

virtual IO::Request *createRequest() override

Create a request object for this device.

Return values:: Request* – Caller must destroy or submit the request

struct Config: #include <Device.h>

class Factory : public IO::Device::Factory

#include <Device.h>

Public Functions

inline virtual IO::Device *createDevice(IO::Controller &controller, const char *id) const override

Create a new device instance.

Called by DeviceManager::createDevice()

Parameters:

controller – The owning controller
id – Unique identifier for the device

Return values:

Device* – The constructed instance

inline virtual const FlashString &controllerClass() const override

Return the expected controller type for this device class, e.g. ‘rs485’.

The Device Manager uses this value to verify that devices are constructed using the correct controller.

inline virtual const FlashString &deviceClass() const override: Return the Device class name, e.g. ‘r421a’.

class Request : public IO::Request

#include <Request.h>

Public Functions

virtual ErrorCode parseJson(JsonObjectConst json) override: Fill this request from a JSON description.

virtual void getJson(JsonObject json) const override: Get result of a completed request in JSON format.

inline virtual bool setNode(DevNode node) override

If nodes are supported, implement this method.
