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!
