Hi,
Thanks a lot, it works.
If I remove mysensors from the yaml I can actually call a reboot again without problems.

i had only the serial usb-gateway in the configuration.yaml

MySensors now works without the entry in the yaml. After a reboot all entities are listed and work. but how can i change the parameters, e.g. the serial port of the gateway?

here the section which concerns mysensors.

mysensors:
gateways:

• device: '/dev/serial/by-id/usb-1a86_USB2.0-Serial-if00-port0'
  optimistic: true
  persistence: true
  version: 'V2.0'

logger:
default: info
logs:
homeassistant.components.mysensors: debug
mysensors: debug

when changing from a tcp gateway (wemos D1) to a serial gateway, i noticed that there must be some differences between the two gateways.

the serial interface does not connect S_Mutimeter and V_Voltage
the TCP gateway can do that without problems

i tried it with my own sketch as well as with MockMySensors.ino.

in mockMysSensors i activate 3 entities. one of them is S_Multimeter.
with the serial gateway only 2 entities are recognized
with the TCP Gateway all 3 entities are recognized.

i use homeassistant version 2023.3.4
MySensors version 2.3.2

who can help here?

best regards

Sorry, also here you can close the post
it turned out that some components were defective.
it took me a long time to discover it and I disposed of the components.
serial gateway works flawlessly with my voltmeter un my motor vehicle.

greetings
branther

thanks again Edi.
I will first make a full backup and put it on a new ssd.
after that i will test your solutions as far as i can.

sorry, i must have overlooked the code snippets function.

best regards

...or did you mean the full protocol?
i have downloaded it. i hope it will be of help.
...
sorry, i can't send upload as file or as graphic. the board always gives error.
it always expects a graphic file.

Hi, thank you for your feedback.
here are the 2 protocols that concern mysensors:

unfortunately my knowledge is not sufficient to understand that

Hi,
i need help again.
when i want to restart or quickly reboot my homeassistant i get the error.
configuration could not be started

"error calling the service homeassistant/reload_all. 'mysensors'"

so i can only do a complete restart.

has something changed in homeassistant in version Core 6.1 regarding MySensors?
best regards

thank you for the link.

thank you,
i use Homeassistant

I have additionally discovered that the WLAN from my LG TV also causes interference.
Then I disabled the wifi on the LG. I do not need it because I have an additional TV receiver.
Now this has also become better.

The change from USB-2 to USB-3, the new 100mF electrolytic capacitor and the 3.3v power supply via an AMS1117 3.3v brought the solution.
Finally no more error led.
thanks best regards

by the way, /opt/apps/mycontroller i don't have this directory.

hi, yes, thank you again
i also use DeepL for my posts. my english is not very good.
yes i use an arduino serial usb gateway
"https://github.com/mysensors/MySensors/blob/master/examples/GatewaySerial/GatewaySerial.ino"
the my_debug protocol is enabled.
#define MY_SPECIAL_DEBUG i didn't know, that's new to me. I will test it.

/opt/apps/mycontroller i will have a look, thanks.

however my problem was not solved after all.
after i reconnected the GW to my raspi, the error-led was activated again every 20minutes.
despite the new electrolytic capacitor (100mF)

after that i suspected that the 3,3v power supply of the arduino nano is not enough to supply the nrf with enough current when sending.
i looked in the shematics and found that the 3.3v comes from the USB-Uart (CH340) of the nano and delivers only little current.
So i installed an AMS1117 3,3V direct on USB-5v which can supply at least 800mA.

i will keep watching but i guess that will not solve the problem.
i think it's a power problem because the raspi can't supply enough power to the usb port either.
ohh, that reminds me, why don't i use the usb-3 port?
i will test it.

next i will connect an external power supply and keep watching.

the problem with the PIR sensors is their duration. You have to move so that they are always reset and restarted or set a fixed time.
The LD2401 are adjustable for range and sensitivity. They respond better to human presence.
I have had good experience with the LD2401-C module.
Firstly, it has 2.54mm mullion connectors and secondly, you can set it up via app using Bluetooth.
The mmVawe-modules are a bit more power consuming than the Pir-module.
Besides plus/minus 5V you only need one pin which gives a high signal when detected.
My light I no longer need switches on the wall
(I have left it in the standard setup and have not yet made any experience with Bluetooth setup).

by the way, the C versions with Bluetooth are immediately recognized in Homeassistant and listed as a device.
... if you have a BL Gateway.
