QwikSwitch setup error


I’m trying to setup QwikSwitch but i get the following errors in the log.

The sample had three spaces before the url which I made two based on the setup/config guide. I also tried removing the quotes around the url itself.

The latter errors are where I was switching a device on and off to see if that is what is needed to get it displayed in the home screen.

Thanks for any help.



Hi Paul,

This is most probably because some devices were not recognized as relays or switches, Pyqwikswitch library v0.3 returns a value between 0-100 for known devices, but for unknown currently just passes the string value through. I will add some checks to handle these cases better.

legacy_status might be a way to decode it any packet. Not sure if switching the value will work then

But lets continue it offline and get it working


HI guys
On initial setup of the qwikswitch plugin it seemed to work okay.
running on ubuntu 14.04 with homebridge and home assistant.
No after a few reboots and no changes the light test dimmer i have hooked up only turns on and fails to turn off
I get this error on switching off:

During handling of the above exception, another exception occurred:

There is also a regular timeout to the script:

16-06-08 11:21:53 ERROR (Thread-2) [homeassistant.components.qwikswitch] <class ‘socket.timeout’>timed out

Perhaps some guidance on this?


So my Python guru made a few changes and now its working:

def _decode_value(self, qs_id, qsval):
    """Encode value to be passed to QSUSB."""
    qstype = self._types.get(qs_id, '')
    self._log('qsval = %s' % qsval)
    if qstype == QSType.relay:
        return 0 if qsval == 'OFF' else \
               100 if qsval == 'ON' else \
    elif qstype == QSType.dimmer and len(qsval) > 2:
        # if we're dealing with a percentage value here
        if qsval[-1] == '%':
            val = (120 - int(qsval.rstrip('%')[-2:])) / 1.2
                val = (120-int(qsval[-2:], 16))/1.2
                # Adjust dimmer exponentially to get a smoother effect
                val = round(math.pow(val, self._dim_adj))
            except ValueError:
                self._log('''Unable to convert hex value in QS dimmer data
                          {}: {}'''.format(qs_id, val[-2:]))
                return -1

        return min(val, 100)

    return legacy_status(qsval)

Hi @eel69, sorry I missed your post. The pyqwikswitch v0.4 library included from homeassistant 0.21 (8 June) should fix this error. It relies mostly on legacy_status
