Hello Adrien,
Unfortunately, the signal camera_detection does not work for me. It always stays on when camera_alarmmode is on and always off when camera_alarmmode is off. Camera_detection doesn't seem to react to the PIR at all. Do you have an idea that could be ahead? Changing the camera_alarmode from on to off doesn't seem to have any effect on the lamp either.

Here is my card configuration in Home Assistant for sending and querying data via MQTT:

After changing the time zone in OPenIPC I was prompted to restart Openipc. After that, the webcam was no longer accessible. Also no more IP address was assigned in the WLAN. Since then, the cam is no longer accessible. What can I do to regain access?

I followed your steps but I'm unable to build the firmware with ipctool. I did not work in Ubuntu 22.04 nor 20.04

Trying to update the firmware using ipctool ends always with an error:

Steinel firmware is the latest "2022-12-07"

The upgrade procedure does not work, the card is formatted no firmware is written:
https://github.com/dirandad/lightcamera-openipc/tree/main/L620#2-backup-original-firmware.
I use a 16GB sd card formatted with FAT32 and the 2 files in the root:
https://github.com/dirandad/lightcamera-openipc/tree/main/L620/scripts/sd-steinel
When I wait 5 minutes the card is formatted by the camera and no telnet is active.

Thank you very much for your effort to analyze the camera firmware and bring it to OpenIPC.
I plan to follow your steps with my Steinel 620, but before I need to know if it is possible to change the stream parameters with the OpenIPC firmware and this camera? The original firmware rtsp stream is HEVC and I need x264 because I plan to use the cam for frigate NVR.
What is required to support the light module/PIR sensor?

Unfortunately, the upgrade.hi3518ev300 file cannot be created. I am using the latest versions of make_images.sh and upgrade_bundle.py, but the following error message appears when creating it.

xxx@ubuntuserver:~/ipctool/tools$ ./make_images.sh hi3518ev300 ultimate
find: ‘../../openipc-firmware/br-ext-chip-*’: No such file or directory

Good afternoon
We are pleased to read your manual and invite you to join the OpenCollective organization on GitHub and get our achive.
Also, if you have a desire, you can migrate and place your materials with us as an administrator of section on your device.
Thank you.

Hello,

I updated the OpenIPC firmware and lost network connection to the device.
Turns out modprobe rtl8188fu no longer works in the current version and the module that is working is called 8188fu.

I fixed it by changing

(I used || just in case they will change it back)

(I didn't do any research on the OpenIPC project if this is a known issue or what the reason is for the change, but thought it may help someone who tries to update or just recently tries to free their L620)

PS: Big thank you for your efforts, great work!

Hello everyone,
does anyone have a picture of how I have to connect the TTL USB adapter to the UART port?

I would like to connect to the u-boot, because unfortunately no WLAN connection is established. I hope this way, I can set the SSID and password via terminal, because the autoconfig.sh file is not executed (although it had worked once). The Camera is already disassembled.
Thank you very much for your great work with this camera.

The communication via MQTT does not work for me. When I start the lightcam application manually, I get the following message:
