ESP32 WiFi Problem


at home I’ve installed three ESP32 and connected them via WiFi the home network.
We have one main router (FritzBox 7590) and two Mesh Repeater (both FritzBox 7490).
The Home Assisstant is running on a Raspberry Pi 4.

All three ESP32 devices are controlling the roller shutters of the whole house (12 in total).
In the ESPHome section of the ESPHome Assisstant, I’ve configured all three ESP32 devices so I can control them in the overview section.
You can open, close and stop the roller shutters from out there.
Every ESP32 device is controlling four roller shutters.

Now the problem:
Every time I am pressing the close or open button in the overview, the related ESP32 device automatically disconnects and reconnects to the WiFi.
That’s really annoying because you can’t use the overview for a few seconds.

I’ve read something about the band width of the WiFi connection, that the ESP32 devices run better with a 20MHz band width but in my case, the problem is still there.

Do you have any advices for me?

If you need any code or screenshots I will upload them.
