I have at least a half dozen ESP8266 and ESP32 devices connected to my router, one of which has been running for over 5 years. They never seem to go down. However, when I check the “online since” feature on in Blynk, the time reported is rarely more than a few minutes previous. I’ll look at 11:30am, and it will say “Online since 11:23am.”
If my devices were truly going offline every few minutes, I’d expect to occasionally find one in an “Offline” state, but that’s not the case. Any idea what I’m witnessing here? Failure of the devices to “phone home” to the Blynk servers frequently enough? An overtaxed router, struggling to serve roughly 20 connections?
Do I even need to be concerned, as long as all devices remain usable?
