Pin 4 not working with homebridge-gpio-blinds library

[matickunaver]

I am experiencing a strange issue. GPIO pin 4 won't work when using this plugin (other pins work). If I use python script, it works. The same setup, python works, Homebridge with GPIO04 not. All other pins are are working.
Attached is my config file (other pins are working) and python file for moving pin 4 manually (also works).
Any idea what might be wrong? Cannot wire it to another pin.

{ "bridge": { "name": "Homebridge", "username": "CC:22:3D:E3:CE:32", "port": 51826, "pin": "031-45-154" }, "description": "", "accessories": [ { "accessory": "Blinds", "name": "Bedroom", "pinUp": 22, "pinDown": 4, "durationUp": 18000, "durationDown": 17000, "durationOffset": 1000, "activeLow": false }, { "accessory": "Blinds", "name": "Work room", "pinUp": 6, "pinDown": 26, "durationUp": 18000, "durationDown": 17000, "durationOffset": 1000, "activeLow": false } ] }

This one works
GPIO.setup(4, GPIO.OUT)
GPIO.output(4, GPIO.HIGH)
print 4, " on"
time.sleep(10)

Could you confirm that in both cases you're using the GPIOxx numbering (not physical pin numbering)? If that's not the case please provide rpio version you're using.
