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

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.

thanks for the links
it didn't occur to me that you can also connect the serial usb-gateway to the pc to debug it.
i thought that has to be done in the linux terminal on the raspi.

ok.
what turns out is that exactly every 20 minutes a
"Send transport network discovery request"
(could have been noticed before, if you know how the gateway works)
is sent but in RED this message :
"Sent Message without radio ACK"
is displayed in the parser.
Well, I suspected that the 10mF capacitor is not enough and replaced it with a 100mF capacitor.
Since then the above message is displayed but the ERROR-LED is not activated anymore.
Here is the output at the parser:

• Sent Message without radio ACK
  Transmitter: 0
  Last Node: 0
  Next Node: 255
  Destination: 255
  Sensor Id: 255
  Command: INTERNAL
  Message Type:I_DISCOVER_REQUEST
  Payload Type: P_STRING
  Payload Length: 0
  Signing: 0
  Failed uplink counter: 0
  Status: OK (OK=success, NACK=no radio ACK received)
  Payload:

Seemingly OK!!?*

The gateway is powered by the Raspi via USB.
It is an Atmel328P 16MHz. 5V Arduino. The voltage for the nrf24 is fed from the 3,3V output of the Arduino.

i think my problem is solved with this. no error led is activated anymore. It was probably due to the too small Elco. exchanged from 10mF to 100mF.
I will continue to monitor it (whether I want or not )

...solved...

best regards.

ohh, did i choose the wrong area for my request?
i ask the admins to move it to the troubleshooter section if possible.
thank you

I have stopped the time between the erros several times.
the error led is triggered exactly every 20 minutes.
I have had all my analog sensors in view. all send in their set time without error.
this gateway error seems to have nothing to do with my transmitters (car voltmeter, home powermeter, 3 thermometers).
exactly every 20 minutes, what can that be?
Can it be triggered by zigbee or wifi?
I have here a Sonof Zigbee dongle and a Fritzbox Lan/Wlan router
If I can not find the cause I will probably disconnect the LED, which is getting on my nerves

best regards

hello all,
I have changed my gateway from wireles (Wemos-D1 Mini) to serial.
among other things, i have also activated the led for errors and connected it to pin-4.
now this errror-led flashes every few minutes, 3-4 times in a row in short intervals.

because the Wemos mini was connected to my PC, i could log via the usb-port to maybe detect the error with the parser.

But since the serial gateway is directly connected to my raspberry, i don't know how to log the communication.

is there a way to detect what causes this error in the serial gateway?

(please understand, i am still a newbie)
best regards

super, once again a few super links, thanks for that

i will go for the easy way. this sketch by boots33 works perfectly.
But before that i will try to understand and learn the steps.
thanks again
