Does anyone know the reason that data logging in the DAY view, has data from 24 hours previous up to 4 hours previous, instead of the full 24 hour period? Screenshot_2018-04-21-19-56-28%5B1%5D|281x500
This screenshot has another anomaly that I don’t understand. It is a Value widget monitoring a two state door switch, so why does the data have non-binary values.
the screenshot you shared does not open. can share a new one.
Here is the full day data log
The other photo is zoomed in to show the non-binary values being included in the binary data
i am not sure why there are values in between. can you share your code.
NOTE V3 is the binary door state
The current and prev door state are BOOLEAN values

in place of this:
use this:
Cayenne.virtualWrite(DoorOpen, 1, "digital_sensor", "d");
this adds a two-state widget having either 1 or 0 value. but on the mobile app this widget does not give a live data view.
Thanks very much. Will make that change. Is there a ref doc with info on what arguments can be passed?

Do you have any thoughts on the data Day view not showing the full prev 24 hrs? Attached are BMP temp and press plots
no. can you keep the sensor ON for one more day and check after that.
Hi
Thanks for the ref doc. I’ve attached two screenshots. Both are taken now, one is week view and the other is day view
Hi
Here is a screenshot from the web interface. The view is after making the change you suggested previously. Both the web and mobile aps are showing the same anomaly, so it is in the data collection somewhere. As a reminder, this is a boolean door state variable which is being displayed on a Value widget in order to get a history log.
can you share the code after the changes i have suggested you.
code as requested
if(currentDoorState == Open) { // action if door is Open
Serial.println(“Open”);
Cayenne.virtualWrite(DoorOpen, 1, “digital_sensor”, “d”);
delay(1500); // delay limits data flow to Cayenne dashboard to 1 cmd/sec
Cayenne.virtualWrite(DoorClosed, 0, “digital_sensor”, “d”);
delay(1500); // delay limits data flow to Cayenne dashboard to 1 cmd/sec
}
if(currentDoorState == Closed) { // action if door is closed
Serial.println(“Closed”);
Cayenne.virtualWrite(DoorOpen, 0, “digital_sensor”, “d”);
delay(1500); // delay limits data flow to Cayenne dashboard to 1 cmd/sec
Cayenne.virtualWrite(DoorClosed, 1, “digital_sensor”, “d”);
delay(1500); // delay limits data flow to Cayenne dashboard to 1 cmd/sec
}
why are you making it on and then off after 1.5ec. is there are specific reason for this. with this you might hit rate limit and have connection interrupt .Sending MQTT messages within rate limits
I want to have the widget respond in near to real-time as possible. Two of the widgets are 2-State for simply displaying the door position, the third is the Value widget which records the event log. I’ll try them at 2000ms and see if that makes a difference. By using delay(), I am forcing a pause in the code so that nothing happens until the time has elapsed, therefore the next Cayenne.Write should be clear to run. At least, that is my understanding of the timing delay limitations. Please correct me if I’m wrong here.
Cheers,
B
what i think is when the door is on keep the two state widget 1 while 0 when close.
unsigned long lastMillis = 0;
unsigned long lastMillis1 = 0;
if(currentDoorState == Open) { // action if door is Open
if (millis() - lastMillis > 10000) {
lastMillis = millis();
Serial.println(“Open”);
Cayenne.virtualWrite(DoorOpen, 1, “digital_sensor”, “d”);
}
}
if(currentDoorState == Closed) { // action if door is Open
if (millis() - lastMillis1 > 10000) {
lastMillis1 = millis();
Serial.println(“Open”);
Cayenne.virtualWrite(DoorOpen, 0, “digital_sensor”, “d”);
}
}
I see that you are introducing a 10sec delay before writing the door state to the widget, but I don’t understand why a boolean argument, can be read as an analog number. It is sending a 1 or a 0, nothing else. So why is the Cayenne data processing s/w giving the fractional results?
i m not sure why it is doing so.may be the way you have added the code. did you try the above code ?
