I’ve implemented this in code in the terminal section. Don’t know how to add the link here but you can search for ESP.reset terminal mohan_sundaram. This will work when device is online. You are asking for info on the Blynk screen to be shown from the server.
For my education. What would that single line of code look like? I’ve captured the epoch number since boot using now(), converted it to days:hours:minutes and then display it. Was definitely much more than a line.
See it on my phone too (Android). However, this is off by 13 minutes. I maintain timestamp of the last connect using BLYNK_CONNECTED() and display it in my terminal for uptime. That is 13 minutes earlier than the time reported by Blynk on its device panel.
Not a critical error or something that breaks any program. Curious to know why the difference occurs. I can understand if my timestamp is later than Blynk’s.
