I’m assuming from your version number that this is the new sketch that you’re attempting to upload.
I had said…
Without knowing how your new sketch compares to the one you’re currently running, it’s to identify possible issues.
You certainly have some logic issues with the event logging code. For example, a reading of lets say 200 gallons would attempt to log 3 events, as 200 is <250, <500 and <750
In addition, these events would continue to be logged every 5 seconds.
Blynk has a log limit of 100 events per day per device, so you could quickly exceed this limit.
This post explains how to use a flag variable to overcome that issue, although in your case you would need more than one variable…
I’m not sure if it matters, but I’d stick with the format from the example, which has 8 spaces.
Have you tried doing a remote reboot of your device?
