After reflashed the ESP (with webtools) the problem is solved.. |

Check the docu: https://jomjol.github.io/AI-on-the-edge-device-docs/StatusLED-BlinkCodes/ Seems a SD card issue... |

I deleted the current data log txt file (it was containing some data with 1-1-1970 date)... and now it appears the value.,. but this is also with no sense

Yes.. I found that info too .. (thanks) |

Why the raw value is correct.. but the value is not shown?

Read the Value Status! Rate too high... |

I do.. but at next read cycle again the value is wrong (one digit more) even if raw value is correct! |

Again.. why the raw value is correct.. but value is wrong? |

After have changed again and again the ROI digit position/size.. it is now detecting properly: it is so sensitive that even changing one or two pixels can make the difference in proper/not proper detection |

Hmm.. so it can be that now I start to have problems with my sdcard because of this change? |

Also make sure you have a good power supply and a good SD-Card! |

Sure.. they are both good and I never had problems until now (until they are now not good anymore as coincidence) |

What does it mean ? |

HLK modules do not have capacitor to smooth the power consumption. |

hmm.. didn't know that .. can you pls explain it better? Consider that from HLK to the ESP32 there is a 7/8 meters cable.. (my water meter is in the garden) |

Aluminium electrolytic capacitance, have a look at https://datasheet.lcsc.com/lcsc/2310091637_HI-LINK-HLK-PM03_C209904.pdf DC current is very sensitive to the type of cable used to carry it. The lower the resistance of the cable, the lower the loss. The type of resistor depends on whether you are using 5 V or 3.3 V. I recommend using 230V in your garden, then converting to 5v with a simple USB transformer. |

Also, I would not trust any 230V device from Ali Express! I have seen stuff from there I would not even power in my lab just for testing. Like @nliaudat sayd, you could pull 230V close to your device if possible. Alternatively (how I do such things), have a 12V power supply which provides the power close to the device. Due to the length and cable lose, it might only be 9..10V at the end. But that is not a problem. use a power regulator like a LM7805 to convert it to the 5V and use some block condensators to stabilize the power. |

Many thanks for all these suggestion and precious information.. See below |

Update: as test I tried to access the web interface after about 20 hours of uninterrupted running.. and it immediately restarted.. Considering that the same setup/same powering was running without problems for over a week with 15.4 version (i was accessing web interface very intensively without any issue).. and now with 15.5 I have this issue I can assume/conclude that this version is much more power demanding.. Does it makes sense? |

Do watever you want, but it is clear that your power supply setup is indufficient. |

On the other side he good thing of 15.5 is that there is no more memory leak.. |

The Problem
After the update to latest 15.5 I am experiencing totally hangs (it doesn't even respond to ping) after few minutes of running..
I cannot find anything relevant in the logs (standard logs.. )
Anyone else with same problem?
