Library for the GryfSmart system

GryfSmart

GryfSmart is a system that enables control of Gryf smart system devices via an RS232 serial port. The core of the system is the pygryfsmart.api.GryfApi class, which provides functionalities for managing devices, such as sending commands, controlling device states, monitoring device statuses, and resetting devices.

Installation

To use GryfSmart, you need to install the necessary dependencies and import the pygryfsmart.api.GryfApi class.

Install Dependencies

pip install pygryfsmart

Device Class

Constructor: GryfApi(port, callback=None)

Creates a new Device object that connects to the device via the RS232 serial port.

• port: The serial port to which the device is connected (e.g., 'COM1', '/dev/ttyUSB0').
• callback: An optional callback function that will process data returned by the device.

Methods of the Device Class

set_callback(callback)

Sets the callback function that will be called when data is received from the device.

• callback: The function to invoke when data is received.

stop_connection()

Stops the connection to the device. It cancels active tasks related to the connection and state updates.

start_connection()

Starts the connection to the device by creating a task responsible for receiving data.

send_data(data)

Sends data to the device via the RS232 serial port.

• data: The command or data to be sent to the device.

set_out(id: int, pin: int, state: OUTPUT_STATES | int)

Sets the output state of the device. This can include turning on or off various output pins.

• id: The device ID.
• pin: The pin number (1 to 6).
• state: The output state (e.g., ON, OFF, TOGGLE).
  • you can import OUTPUT_STATES enum from pygryfsmart.const

set_key_time(ps_time: int, pl_time: int, id: int, pin: int, type: KEY_MODE | int)

Sets the key press time for the device.

• ps_time: The short press time in milliseconds * 10.
• pl_time: The long press time in milliseconds * 10.
• id: The device ID.
• pin: The pin number (1 to 6).
• type: The type of the key.
  • you can import KEY_MODES enum from pygryfsmart.const

search_module(id: int)

Retrieves information about the device model and assigns an ID.

• id: The device ID.

search_modules(last_module: int)

same for multiple devices, starting from 1 to last_module.

• last_module: The number of devices to be searched.

ping(module_id: int)

Sends a ping to a device to check if it is responsive.

• module_id: The device ID to ping.

set_pwm(id: int, pin: int, level: int)

Sets the PWM level for a specific pin on the device.

• id: The device ID.
• pin: The pin number (1 to 6).
• level: The PWM level (0 to 100).

set_cover(id: int, pin: int, time: int, operation: SCHUTTER_STATES | int)

Controls the cover state for a specific pin on the device.

• id: The device ID.
• pin: The pin number (1 to 4).
• time: The time in milliseconds for the operation.
• operation: The operation to perform (e.g., OPEN, CLOSE, STOP, STEP_MODE).
  • you can import SCHUTTER_STATES from pygryfsmart.const

reset(module_id: int, update_states: bool)

Resets the device. Optionally, updates the states after reset.

• module_id: The device ID.
• update_states: Whether to update the states after reset.

start_update_interval(time: int)

Starts the task that periodically updates the device states.

• time: The interval time in seconds between updates.

Subscribe metods:

subscribe input messages(fun_ptr)

• fun_ptr: Function to handle new messages from controllers.

subscribe output messages(fun_ptr)

• fun_ptr: Function to handle all sending messages.

'subscribe(id , pin , func , fun_ptr`

• id: The device ID.
• pin: The pin number.
• func: selected function, for example DriverFunctions.INPUTS, you can import this from pygryfsmart.const.
• fun_ptr: handle function
