Error message shelly core integration

Configuration
1

Hi.

I´m running Home Assistant OS 5.12: core-2021.3.4 on a windows VM server.

I have about 30 shelly devices and they are configured through ha shelly core integration.
Mostly everything works but sometimes when I´m turning on or off one of my shelly 2.5 it doesnt respond and gives me an error in the log. If I try to turn on/off a second time it works.
What does the error message mean?

Your Shellys are dropping the connection for some reason.

Could be a network issue. What is your wifi hardware setup?

30 clients is pushing the limits of consumer grade all in one wifi/router boxes.

Hi, thanks for reply.

I´m using ubiquiti unifi products.,

Dreammachine pro, USG48 ports switch, 4 AC-Pro ap:s.
Current clients at that ap is 12.

I only have problem with one shelly so maybe its somthing wrong with that device.

Yeah ok, that’s not your problem.

But I think you are right that it is a connection issue.
I noticed now that the device is connected to another ap thats far away and have bad signal.

I´ve updated my shelly devices to the latest firmware and activated ap roaming setting.
The device has 73dB and I´ve set the ap roaming setting to 70dB.
But it doesnt connect to the strongest ap.
After a reboot of the device it´s now connected to the strongest ap with 53dB.

Strange…Ap roaming feature doesnt seems to work

Yeah I found the same issue, it’s kind of rubbish. I ended up giving each AP a unique network (ssid) and hard coded the devices to use the closest one.

Good idea.

It would be great if ha retried the command after it reconnected to the device again.
It works the second time I try to turn on or off.

I mean, ha knows that the command hasn´t been executed and reconnects. Then it should resend the command automatically.
