Chart crashes with large number of datapoints -defect- 2.8.0 (2406062026)

[DG12]

A sensor has sufficient data points being charted will cause a crash. See related default all issue #2042

Example my 450A front door has 107,398 data points! (Didn't know that!) Charting 12 hours takes 12 seconds. taping to next sensor crashes (sometimes!)

[markoaamunkajo]

I cannot initially make my app crash at least, I think not enough sensor data to be downloaded to app.

[DG12]

I have shared '450A front door' with you. that fails (for me) predictability.

Oh Dear! My wife has a iPhone 13 Pro Max (yes!) and it does not exhibit problem (with only 1 sensor)

@DG12 What device you are using?

[priyonto]

You can try login to your wife's device with your account where you have several sensors and try?

I think testing with such small number of datapoints (full 10 day sync from the cloud has only less than 3k points) will not reveal any issues. The big question ia that how the heck your sensor has over 100k points stored in your phone??

1min interval for 10 days would be only 14 400 data points.

Sensor 450A is transmitting via advertisements to iPhone, i.e. NOT via gateway. 2024-05-27 21:15:23 2024-05-27 21:16:24 2024-05-27 21:17:24 2024-05-27 21:18:23 2024-05-27 21:19:24 2024-05-27 21:20:24 ... 2024-06-06 21:14:35 2024-06-06 21:14:37 2024-06-06 21:14:40 2024-06-06 21:14:43

107,454 datapoints

What kinf of bg scanning settings your app has? Every 1min? And do you keep the app on foreground how much? When on foreground, all datapoints are saved to database. If the app is open long times, that could explain this.

Deleted app and data. fresh install (200403012040) add only one(1) senosr, No change in settings. Added new user DG1@cccu.us . Download history from sensor only gets 2,870 entries

2024-05-28 11:57:44 2024-05-28 12:02:44 2024-05-28 12:07:45 ... 2024-06-07 11:30:45 2024-06-07 11:35:46 2024-06-07 11:40:46 2024-06-07 11:45:47

Now collecting at much faster rate (as expected) No change in settings, i.e. settings as installed.

I try to have station running in background all then time, however drains iPhone battery really quickly.

[priyonto]

@DG12 I can't reproduce the issue, neither with your sensor nor mine.

[DG12]

I have deleted all data and installed 240607 1700 . Added 8 sensors (3 just now) Synced 450A, 3B86, 53F1, AD03, BB12, 20BC locally stored measurements 30,659 ; Database size 7.5MB

5 days, scroll through all OK 10 days SPLAT! 7 days OK 8 days SPLAT! 8 days OK !! 8 days OK 9 days OK 10 DAYS OKAY!! minimize 10 Days ( PS not even grunty perhaps a second or 2 on sensorsn with most data) close station (and all the other apps too )

startup now 31,912 measurements 7.8MB 10 Days OKAY !

What can I say!
