Hello,
im writing with some problem. when im running this in python3.6:

from miio import Gateway

gateway = Gateway("192.168.1.201", "3473613977763634775674464d653232")

print(gateway.send("get_device_list"))
i get result
[{'did': 'lumi.158d0001f50a33', 'model': 'lumi.weather.v1', 'num': 1, 'total': 6}, {'did': 'lumi.158d0001f52069', 'model': 'lumi.weather.v1', 'num': 2, 'total': 6}, {'did': 'lumi.158d0001fa6d43', 'model': 'lumi.weather.v1', 'num': 3, 'total': 6}, {'did': 'lumi.158d0001fa80bb', 'model': 'lumi.weather.v1', 'num': 4, 'total': 6}, {'did': 'lumi.158d00027cf600', 'model': 'lumi.sensor_cube.aqgl01', 'num': 5, 'total': 6}, {'did': 'lumi.4cf8cdf3c7e54c7', 'model': 'lumi.plug.mmeu01', 'num': 6, 'total': 6}]

but, when im doing it like this:
[root@xxx]# miiocli gateway --ip 192.168.1.201 --token 3473613977763634775674464d653232 discover_devices
Running command discover_devices
Error: {'code': -5015, 'message': 'device not found'}
