Unstable wifi connection with CREATE Windcalm fan

[Redstylt]

Hi,

I followed all the steps to include my fans from the brand CREATE, model Windcalm wifi, in my HA.
I struggled a little but I ended up succeeding.
On the other hand, now I regularly have an unavailable status even though the fans are in a room with a wifi repeater! the signal strength should not be a problem.
Moreover, when I open the Tuya app, the fans are well connected and responsive.

Here is the error status in the HA logs:

This error comes from a custom integration

Recorder: custom_components.tuya_local.device
Source: custom_components/tuya_local/device.py:713
integration: Tuya Local (documentation, problems)
Happened for the first time: 01:25:55 (26 occurrences)
Last record: 10:27:16

Failed to fetch device status for Ventilateur bureau
Failed to fetch device status for Ventilateur chambre

What can I do to have a stable connection? That the fans are available in my HA at all times.

Thanks for your support.

Other than WiFi strength, it can also be that your router is overloaded. The number of connections your router can handle reliably is linked to the amount of RAM and CPU speed of the router, which can be insufficient on lower end one (typical of the ones that ISPs will provide).

Is there a way i can check this ?
But also it's weird that Tuya app handle it great and not HA
