Request: improove integration for other devices.

[bennydente]

Hi,

i'm not realy a developer but your integration work fine with my USR-WP1 smart plug, USR-WM1H and USR-WM1S 1 channel switch.
I have modified code like this in switch.py discoverying jut one entity:

before:

 def devices_from_entities(hass, entry):
     """Parse configuration and add USR-R16 switch devices."""
     device_client = hass.data[DOMAIN][entry.entry_id][DATA_DEVICE_REGISTER]
     devices = []
     for i in range(1,17):
           device_port = i
           device = R16Switch(device_port, entry.entry_id, device_client)
           devices.append(device)
     return devices

after:

  def devices_from_entities(hass, entry):
      """Parse configuration and add USR-R16 switch devices."""
      device_client = hass.data[DOMAIN][entry.entry_id][DATA_DEVICE_REGISTER]
      devices = []
      device_port = 1
      device = R16Switch(device_port, entry.entry_id, device_client)
      devices.append(device)
      return devices

So if you want to improove integration.... bye.
