on the drawing I forgot to put also the

..... back on my computer

hello skywatch jkandasa

thank you for this clear explanation guys

. the backup of infuxdb

the one recopy with the tree command

@odroidc2:/var/lib$ tree influxdb
influxdb
├── data
│   ├── _internal [error opening dir]
│   └── mycontroller [error opening dir]
├── influxd.pid
├── meta
│   └── meta.db
└── wal [error opening dir]

@odroidc2:/var/lib/influxdb/data$ sudo tree mycontroller
mycontroller

the directory /var/lib/influxdb/data/mycontroller/
and thus to save

the link for information on cron cron
(it's easy once you understand it)

two questions about backup

1 : the cycles of backup program overwrites the old backups ? or it is incremented ?

2 : for the restoration, example.
---- installs new-----
- a new blank installation of myC

• copy and create the directory /opt/backups/ with the backup in it, then launch : Settings-->Backup Restore

for a clearer view of the state, a mental comfort.
on which scale we are ?

yes one more thing can be possible

pdf vue

I redo a clean installation.
by following the modification of the tuto .

there is an error message for the installation of influxdb

 wget -qO- https://repos.influxdata.com/influxdb.key | sudo apt-key add -
Warning: apt-key is deprecated. Manage keyring files in trusted.gpg.d instead (see apt-key(8)).
E: This command can only be used by root.

Fix “Waning: apt-key is deprecated. Manage keyring files in trusted.gpg.d instead”

"Even if this is a warning message, you can continue to use apt-key, but it will be removed in the next releases. So it will be a good idea to start using the new way."

"Solution:
..... new way of adding GPG keys to the system and avoiding the above warning.
The following command will download a remote GPG key, encrypt it and save it..... "

see how we can solve the problem.

and maybe upgrade to version 2 of influxdata?

yes several possible philosophy.

use the same server as myC to install a video surveillance application, and encapsulate it inside.

or externally, for example an ESP32-CAM https://www.sigmdel.ca/michel/ha/esp8266/ESP32-CAM_01_fr.html

my idea of WebCam at the beginning it was a simple rear view mirror
to have a view on my doorway, the door rings (arduino) and the webcam turns on in myC .

a possible choice of video surveillance
Alternatives

opinion: Zoneminder Motioneye Shinobi

yes a test .

but I did not succeed, the world becomes more and more complicated, I tested with 4 different tutorials, even installs with compilation, there is always a file or a version which is not with the appointment

but the Nginx server is cool, I will be able to use Hugo for my personal pages.

and MyController is still operational after all it's DIY

so for WebCam and MyC
I let another person prepare a tuto

WebCam <----direct link -----> MyC

..... hello jkandasa

review of the day
and of the night

FFmpeg abandons the FFserver part "Removed the ffserver program
https://trac.ffmpeg.org/wiki/ffserver

installing an old version would be possible, but the past is not the future
https://ffmpeg.org/releases/?C=N%3BO%3DD
https://www.tecmint.com/install-ffmpeg-in-linux/

or maybe https://github.com/klaxa/ffserver
"This project aims to replace the hard to configure and maintain old FFserver component of the FFmpeg project"

a test with the mkvserver_mk2 replacement or Srs not give anything clean (too complicated for me or doc too complex or language badly translated )
https://github.com/klaxa/mkvserver_mk2
https://github.com/ossrs/srs

Now I test NGINX https://www.codeinsideout.com/blog/pi/stream-ffmpeg-hls-dash/#apache
( a light web server application, but without server ?)

.... to follow!

webcam and MyController

use of a Usb webcam connected to the myC server for direct viewing in a widget.
(no Http)

installation uvccapture

(for the usb-webcam link)

- sudo apt-get install uvccapture

• ls /dev/video*

installation ffmpeg

( for image manipulation)

• sudo apt-get install ffmpeg

start ffmpeg

ffmpeg -y -f v4l2 -video_size 1280x720 -i /dev/video1 -r 0.2 -qscale:v 2 -update 1 /opt/apps/mycontroller/executable/mc_home/secure_share/image/webcam.jpg

And Test Gif

sudo ffmpeg -ss 30 -t 3  -video_size 640x420 -i /dev/video1 -vf "fps=10,scale=320:-1:flags=lanczos,split[s0][s1];[s0]palettegen[p];[s1][p]paletteuse" -loop 0 /opt/apps/mycontroller/executable/mc_home/secure_share/image/output.gif

https://superuser.com/questions/556029/how-do-i-convert-a-video-to-gif-using-ffmpeg-with-reasonable-quality

Be careful, it doesn't really work, it's a test.

Now jkandasa I'll need your help / idea for the next step.

1st : Can MyController display a video ?
(in the widget the unrecognised formats
.mov and .mp4 .avi )

2nd : Can MyController turn on the Webcam when you go to the Widgets page, and turn it off when you leave ?

Philosophy of the idea :
- a non-shared webcam on LAN or WAN, no video stream from the webcam on the LAN, only a video stream between
WebCam <----> MyC

Hello Yourry and welcome to MyController
(which is super light and reactive)

I was in too much of a hurry to reply yesterday, without thinking

something that jkandasa had already explained to me

thank you jkandasa

the installation procedure is updated

finally find for a creation and clean up of the oxt files

the latest version arduinoMYC.oxt
still some symbols to add and errors to see

why this work ??? ... for a rescue wheel and fun

Hello

a discovery, a rediscovery of a program that has evolved enormously, the last time I used it was in the year 2000.

... thank you jkandasa it's thanks to you that I found it

The one creation of symbols with the sauce myC
( attention it is my 1st use and some are not very well finished, it is a beginning)

I have not yet found how to give you my library.
I give them to you in the form of board to copy in your LibO_draw

MyC_architecture_Odroid.odg

MyCsymbol.odg

liens:
https://www.libreoffice.org/
https://documentation.libreoffice.org/en/english-documentation/
https://help.libreoffice.org/Draw/Welcome_to_the_Draw_Help

to avoid further errors.
which directory / command for the installation ?
yes this sentence translated in french is wrong " Pas dans mycontroller/executable"
thanks

create a directories to keep MyController server data and executable - arm64
- sudo mkdir -p /opt/apps/mycontroller/mc_home
- sudo mkdir -p /opt/apps/mycontroller/executable

create directories to keep image files to show it MyController dashboard
- sudo mkdir -p /opt/apps/mycontroller/mc_home/secure_share
- sudo mkdir -p /opt/apps/mycontroller/mc_home/insecure_share

download the bundle and extract on executable directory
- cd /opt/apps/mycontroller

what is the error ???

a test with LibreOffice Draw

so this part is not good ???
Re : Armbian - MyC V2 - install

create directories to keep image files to show it MyController dashboard
	sudo mkdir -p /opt/apps/mycontroller/mc_home/secure_share
	sudo mkdir -p /opt/apps/mycontroller/mc_home/insecure_share

I would say only one thing
BRAVO

a question: what software do you use for the graphic "architecture.png" ??

Well, that's okay, we'll just put it aside.
We'll see later.

I will probably do a new installation.
I'm testing tomorrow a webcam and mjpg-streamer
