DeviceError when trying to turn on my Xiaomi Mi Smart Pedestal Fan

[PRO-2684]

Describe the bug
I can get information about the fan using:

import miio
fan = miio.Fan(ip='...', token='...')
print(fan.info())
# Output: dmaker.fan.p5 v2.1.3 (**:**:**:**:**:**) @ 192.168.**.*** - token: ********

However, when trying to turn it on using fan.on() and get its status using print(fan.status()), I got miio.exceptions.DeviceError: {'code': -9999, 'message': 'user ack timeout'}. I've retried several times, but the error still occurs. The Mijia app works, however.

Version information (please complete the following information):

• OS: Windows 10
• python-miio: 0.5.6

Device information:

• Model: dmaker.fan.p5
• Hardware version: esp8266
• Firmware version: 2.1.3

To Reproduce
Run the code below.

import miio

ip = '***'
token = '***'
fan = miio.Fan(ip=ip, token=token)
fan.on()

Expected behavior
I expected the fan to be turned on.

Using fan = miio.Fanp5 solves the problem.
