Smarthome.py plug-in for Helios ventilation systems

Helios Plug-in for Smarthome.py

Plug-in for Helios ventilation systems using an USB RS-485 interface for SmartHome.py.

Currently running for my Helios EC300 PRO using the USB-RS485 Interface EXSYS EX-1303.

Supported functions:

• Reading temperature values
• Turn ventilation system on/off
• Switching between summer/winter mode (bypass)
• Read/Write fan speed
• Read/Write bypass temperature
• Read/Write maximum/minimum fan speed.

Values will be read periodically from the ventilation system.

Plug-in can be used as command line tool (Python module argparse required).

    class_path = plugins.helios
    tty = /dev/ttyUSB0
    cycle = 60 # default 300 seconds
