The problem

I have a Xiaomi Smart Air Purifier 4 Lite. i started to notice that the device on my dashboard keeps showing the device as unavailable.
it was working well last year. i just did not notice when or which version did the issue start on. i was just expecting that the next update would fix it.

when i look at the device integration i see this in the log.

from the Home assistant core log

`Logger: homeassistant.components.xiaomi_miio Source: helpers/update_coordinator.py:347 integration: Xiaomi Miio (documentation, issues) First occurred: May 18, 2024 at 9:50:15 AM (396 occurrences) Last logged: 7:28:11 PM

Error fetching Xiaomi Smart Air Purifier 4 Lite data: Unable to discover the device 10.2.8.87 Error fetching zhimi.airp.rmb1 data: Unable to discover the device 10.2.8.87 `

XiaoMi's own app does not show that the device is disconnected. the firmware of the device is 2.2.1.0058 ( from the xiaomi app)

actions i've tried:

1. remove the integration and add it back.
2. use both automatic and manual configuration.
3. power cycle the Xiaomi air purifier.
4. power cycle the home assistant PC.
5. tried the reload option from integration.

I have the same issue with my Roborock S5. I've noticed that opening the Xiaomi Home app seems to get the device back online, until it eventually becomes unavailable again. It looks like the device network interface goes into sleep mode when the app is not open and the Android app will wake it up when trying to fetch information. NB: the device seems to occasionally wake up on its own as well. This definitely is a new behaviour, I suspect a recent firmware update causes this.

Yesterday I started testing sending a WoL magic packet to the device when it becomes unavailable in HA. So far this seems to do the trick: this will get the device back online the next time HA polls it (in the next 30s). This is not ideal but at least reduces the time the device appears unavailable. After running this for a few weeks, this seems to have been a coincidence and it doesn't solve the issue.

Same with Smartmi Fan 2S and Air Purifier 4. Devices just disconnect (while still online in Xiaomi Home) intermittently.

Same problem here with the Xiaomi Smart Standing Fan 2 Pro (dmaker.fan.p33). Although it’s not in the supported devices list, it worked nicely up until recently for me.

Mi Air Purifier 3/3H (zhimi.airpurifier.mb3) also affected

Same for my standing fan 3

I am also having this issue. I do have an air purifier, which becomes unavailable at certain point of time. Later I discovered that this is happening when internet goes down. When internet is up, all services which depends on internet will up in home assistant except this one

Update - I have added a scheduled restart of my router at 3 am in the morning and i guess this causes this issue.
