Virtual HomeMatic CCU XML-RPC Server with fake devices for development.
If you develop applications that communicate with a CCU (or Homegear) via XML-RPC, you can use this server instead of a real CCU. It currently provides all HomeMatic Wired and HomeMatic Wireless devices (allthough some devices with multiple similar channels with just a single channel). HomeMatic IP devices will follow.
The main objective is to provide you access to all available devices without owning them, as well as not stressing your CCU / messing with your devices while testing your work. It should also be possible to use this for automated testing / CI.
The init method used to subscribe to events is available and functional. Events will be fired when you use the setValue or putParamset methods to change parameters of a device.
When adding the logic argument while creating the server-object, modules found in device_logic will be loaded depending on which devices are enabled. For example: the module HM_Sec_SC_2.py fires two events at the specified interval. The STATE toggles with every event, and LOWBAT gets toggled every 5 events.
The startupdelay randomizes when the eventloop will initially start from 0 to startupdelay seconds. This is to prevent multiple devices from firing their events at the same time.

Usage
import pydevccu
# Create server that listens on 127.0.0.1:2001
# To listen on another address initialize with ("1.2.3.4", 1234) as first argument
# Add optional list of device names to only load these devices
# Enable paramset persistance (will be saved to paramset_db.json)
# Enable automated device logic (only if module for device is available), firing events at intervals of 30 seconds
s = pydevccu.Server(devices=['HM-Sec-WDS', 'HM-Sen-MDIR-WM55', 'HM-Sec-SC-2'], persistance=True, logic={"startupdelay": 5, "interval": 30})
# Start server
s.start()
# Get address for a HM-Sec-WDS device
s.supportedDevices()['HM-Sec-WDS']
# Get device description
s.getDeviceDescription('VCU0000348')
# Get VALUES paramset for channel 1
s.getParamsetDescription('VCU0000348:1', 'VALUES')
# Get current state
s.getValue('VCU0000348:1', 'STATE')
# Set state to 2
# Set force=True because parameter does not allow write operations (it's a sensor updated by hardware in real life)
s.setValue('VCU0000348:1', 'STATE', 2, force=True)
# Set state to 1 using the putParamset method
s.putParamset('VCU0000348:1', 'VALUES', {'STATE': 1}, force=True)
# Trigger PRESS_SHORT event for HM-Sen-MDIR-WM55 on channel 2
s.setValue("VCU0000274:2", "PRESS_SHORT", True)
# Add a HM-CC-RT-DN device during runtime
s.addDevices(devices=['HM-CC-RT-DN'])
# Remove the HM-Sec-SC-2
s.removeDevices(devices=['HM-Sec-SC-2'])
# Stop server
s.stop()
