I have built a simple Temperature data LOGGING system. Concept is that the processor (esp8266) wakes up once a minute - inits data - connects to the WiFi - connects to Blynk Server (local server) - reads the BME280 data - sends 8 lines of data (to Labeled Value Widgets) - then goes into Deep Sleep.
In general this works great - however about every 3 cycles - the last piece of data sent - fails to show up in the application. This one is the Log Entry time - so this is an easy one to know since the “log entry counter” (which is the 1st of the 8 entries) shows I did an update - but the time value (which is the 8th one - last value) is not updated each time.
So my question is - is there some value or function in Blynk that I can check - to be certain the data was “sent”.
