[Bug] homebridge doesn't turns off shelly 1L
Plugin correctly discovered my shelly 1L device and allows to turn it on but when I try to turn it off - it does nothing. Accessory is marked Off but no efect in reality. and then I can turn on, off, on, off etc without any result, unless device is switched off otherwise. Then again first turn on attempt is succesfull
