Python code for controlling Brematic remote power outlets and potentially other stuff

Project description


Build Status PyPI version Coverage Status

The topic "smart home" or "home automation" in particular has become increasingly popular throughout the last few years. While many manufacturers are relying on cloud infrastructure, there are some that produce local-only devices, using the 433 MHz ISM band.

The python module "pyBrematic" enables you to control and automate your 433 MHz remote power outlets (and other switches/dimmers) with the Python programming language. All you need for this is a supported 433 MHz network gateway, such as the Intertechno ITGW-433, the Brematic GWY 433 (or CONNAIR 433, which is basically the same as the Brematic one).

With the help of the community we might get other devices working as well.


This module is available on pypi and hence can be downloaded via pip like this:

pip install pyBrematic

And if you are having issues with installing the package, try to use the --user switch, to install it to your home directory.
PyBrematic has no external dependencies. Only Python versions >= 3.5 are supported.

Example usage

To check out how to use the module, go to the example file. There you'll find an example configuration of how to use the module.

from pyBrematic import Action
from pyBrematic.devices.brennenstuhl import RCS1000N
from pyBrematic.devices.intertechno import ITR3500, calc_system_and_unit_code
from pyBrematic.gateways import BrennenstuhlGateway

# Set your system and unit codes
system_code = "11110"  # DIPs 1-4 are in the 'up' position, 5 is 'down'
unit_code = "10000"  # DIP A is in the 'up' position, B-E are 'down'

# Create a new device with the specified codes
desk_lamp = RCS1000N(system_code, unit_code)

# For Intertechno devices you can also use the following methods to get the code
# via master/slave (letter/number) notation. Allowed values are "A-P" and "1-16".
led_system_code, led_unit_code = calc_system_and_unit_code("A3")
led_strip = ITR3500(led_system_code, led_unit_code)

# Create a new gateway located at the specified IP
gw = BrennenstuhlGateway("")

# Send the request and pass it the device and the action (on/off)
gw.send_request(desk_lamp, Action.ON)
gw.send_request(desk_lamp, Action.OFF)

Important notice

Since all data packets are sent to the gateways via UDP, it cannot be guaranteed, that all requests will be received by the gateway. For critical purposes you cannot rely on sending the signal once.
