re-Edit
Merci, I finally understood about the curves, excuse me .
.... next, "Do you see problems on the other widgets ?"
No everything is good, the widgets are easy to duplicate, the system is stable and responsive; really good ... great MyC.
a new question 
is it possible to navigate between the dashboards without going through the top dropdown menu?
widgets that call other pages, other dashbords!
a good week to you
Hello
the problem is solved, Mycontroller did not stop.
Impecable 
Thank you for the information, for the sckect with V_STATUS on the forum of MySensors.
I give you more work than I help you.
Have a nice day.
.... go on I continue
French version in service
words to be revised, 10 % of waste ?
if a Frenchman passes by that he gives me a return
for an improvement
Thanks a lot Jkandasa
can't figure out how to make my backup
(I still made a full backup : mv mycontroller mycontroller_old)
so I redid a MyController Installation
the result
I reconnected and reconfigured the Arduino-Usb Gateway and everything went up automatically without doing anything in MyC, a pleasure.
for the dual Sensor "mixed resources in Table" yes it's perfect
( a return in images later )
the evening video ... good evening
Yes really nice, less violent for the view
Ps: I redid a total installation of MyController, so I know what I'm starting with.
Hello
here is my sketch is clean and functional.
the values sent with the bodyboard work well.
one step finished
now i tried with the examples of the schedules you gave me, and well i'm lost
I recapitulate the need.
MyC sends at a certain time or day, the value of on and off
for the time slots of the relay on the clock.
integer values without comma,
example : 1630 for 16hours 30minutes.
the sketch of MyS manages with
Thanks for your help.
many stars in the sky for you
the recopies and other info
the parts of the sketch

Thank you @jkandasa
it's very good like that , it works well
I put at 10minute /Node State Updater/ Execution Interval
"I'll try to document things MyController," ... yes the Labels / Key /Value part
. what tree structure
. family ? structure ???
. how to use them ?? create them ??
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
liens:
https://www.libreoffice.org/
https://documentation.libreoffice.org/en/english-documentation/
https://help.libreoffice.org/Draw/Welcome_to_the_Draw_Help
on the drawing I forgot to put also the
start/end the mini/maxi 0/50
..... 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

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
for a clearer view of the state, a mental comfort.
on which scale we are ?
yes one more thing can be possible
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
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)

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
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
