Sonoff and Ewelink are going crazy - disconnecting for no reason.

Hello, I have pored over the smart stuff in my house, specifically this:

- sonoff Dual R3 roller shutter controllers
- lED drivers Sonoff Basic R2

In addition, to improve the range, I have a Mercusys ME60X repeater


The problem is that on random days and times it disconnects some devices in the eWeLink app, it just grays out and shows that the device is OFFLINE.
This is strange because nothing is being buried, nothing is limiting coverage.
Yes, after a while - sometimes longer, sometimes shorter - the problem resolves. If, on the other hand, I reset the repeater, then after the reset the problem is immediately solved and the devices are ONLINE.

I don't know if it's the channels over Wi-Fi or what, but it's annoying already.
Today was the 1st time that I got up at 6:00 am and the LEDs were on, which turn on at 8:00 pm in the evening and could not be turned off in the app because they were "OFFLINE"....

Mercusys ME60X ustatly firmware update dated 2023-11-24.
Were faulty replace repeater.

Yes, it's just that not all the devices I mention are connected via a repeater....

Some of them are connected directly to the Wi-Fi without a repeater, and still disconnect.

and which router?

This is the one I got from the fibre optic operator.

1.Instead of a repeater, use an AP
2. Instead of a Chinese cloud your own server and possibly your own VPN or Tailscale, Zerotier etc.
And the problems will disappear

1. I wrote that it's not just the devices that are further away, after the repeater, but also those that are closer to the base router.
2. How do you make your own server for such things?

Black magic for me... Another solution is needed.

Okay, now here's the situation, I wanted to connect to the wifi on my phone at 2.4GHZ, can't, doesn't connect me....

At the same time, ONLY those devices that are connected to the router on 2.4ghz (not to the repeater, but to the router) do not work.



On the other hand, I can connect to a 5Ghz network without any problem, but the sonoff does not support it ... so it is something with the router and the 2.4ghz band.



What is the issue, why doesn't the 2.4 band work but the 5Ghz band works and connects?

No idea? it was the same today, same disconnection and no way to connect to wifi after 2.4ghz....

The ideas can be many. From a broken router to heavy interference on the 2.4GHz band

according to ip scanner I have 29 active wifi device connections on 2.4ghz, according to the router I can have a maximum of 32 active connections, could this be from this ?

Well, you have answered yourself. Add an AP and set the channels appropriately so they don't overlap, split the traffic between the AP and the router. And it has to be a real AP, not a repeater. Unless your repeater can work as an AP. i.e. connected via LAN cable to the router and working without NAT.

is there a cheap and good AP you recommend that can handle this?

Put a Deco X50 and it will work, I have 15 Ewelink and 25 Tuya. and 3 Deco
