Hello!
I use the history graph to check the status of an Led which has two values 0 and 255. If the led is enabled or disabled for long time (no changes), the history line doesn’t keep drawing the line at that value. This is an issue for real time tracking (mostly in 1h frame), when the value changes again, the graph will connect all values again.
Example:
– on
_ off
# non visible off value
––_########
Kind regards
P.S. Also note, that i don’t send data from hardware to blynk server when the state didn’t change.
