Tuya Developer Forum

I have had a few Tuya devices for about a year, and they worked fine.

I now added 20 lightbulbs and plugs.

1-2 times per day, ALL the Tuya devices (including the ones I had before) go offline, but all other non-Tuya WiFi keep working fine.

How come ALL the Tuya devices go offline together? If it were only a few, I would say it is WiFi congestion, but since it is all of them, there must be a common problem of the Tuya devices?

How can I fix this behavior? Thanks for any suggestions!

Do all the devices including non-Tuya Wifi devices connect to the same router?

You could try to reboot the router if all the Tuya devices go offline together next time. I'll appreciate it if you send the operation result here.

I had similar case, after several experiments with rebooting/reconfiguring router/Tuya devices and analyzing behavior I conclude that Tuya devices somehow conflicted within other non-Tuya devices in one WiFi network, when they became critical number. In my case its about 60 online connections. After adding separate WiFi network (MESH) appointed only for Tuya devices, all works smoothly. Notice, I've using Linksys EA9500 and Mikrotik L009 powerful routers in hope to resolve that issue, however it doesn't helped.
