python-miio Bug TimeOut Dreame F9, works intermittently

Describe the bug The device responds intermittently, following a disconnection or reconnection, it responds 1 or 2 times, then nothing

Version information (please complete the following information):

OS: [e.g.Linux] Linux 5.10.103-v8+ Debian GNU/Linux 10 (buster) 64bits (aarch64)
python-miio: version 0.6.0.dev0

Device information:

Model: dreame.vacuum.p2008
Hardware version: Linux
Firmware version: 3.5.8_1050

To Reproduce I would like the robot to respond

sudo miiocli genericmiot --ip 192.168.10.32 --token MYTOKEN info or sudo miiocli dreamevacuum --ip 192.168.10.32 --token MYTOKEN info

ERROR:miio.miioprotocol:Got error when receiving: timed out ERROR:miio.click_common:Exception: No response from the device ...

Expected behavior

Console output miiocli discover

This is probably related to #1751 - the problem is that miiocli does not save the sequence id when exiting, and some devices will simply ignore new requests as they think they have already answered them. A simple way to test if that's the case is to wait a minute or so between requests. If that works, this will be fixed when the linked issue gets implemented.

Hello and thank you for your reply, I have tried using the miiocli genericmiot and miiocli dreamevacuum commands at larger intervals, without success.

@rytilahti Hello, I can communicate with the robot, but I have to query it once before with "viomivacuum", then "dreamevacuum". without that, no communication

It works after cold booting the robot, but stops working after a while. Controlling the robot with the app however still works.
