mysensors on rpi with NRF2401 with Domoticz

[goblin]

hello all,
the best thing on my Domoticz was MySensors.
But is was because Domoticz crashed during the latest update.
I had ti re-buid it but i can get MySensors back to work.

The NRF pcb is directly connected to the MOSI and MISO of the RPI connector.
But i have only three posible choices in hardware on Domoticz.
MySensors Gateway with MQTT, with LAN interface or USB.

What do i have to do to get it working again.

i have 10 MySensors units and 15 esp via MQTT units and since MySensors are the most reliable so don't want to change it to ESP-MQTT

Thanks

Hello @goblin, welcome to the forum.

You probably had installed the raspberry pi gateway, which supports serial (usb), ethernet (LAN) and mqtt.

Instructions: https://www.mysensors.org/build/raspberry

Easiest is probably ethernet.

[goblin]

that's correct. but i seems to have a problem with the correct Domoticz settings.
I need to select one out of three and i get a message "Error: rf: Failed to start, return code: 14/Connection refused (Check IP/Port" when select mqtt
and when select LAN the message "Error: rf: Can not connect to: 127.0.0.1:5003".
so it's obvious that i have did something wrong.

Thanks

good evening,
I have tried ./configure --my-gateway=ethernet --my-controller-ip-address=127.0.0.1
But still the same error

Thanks

[goblin]

good night :)
i have tried "Step-by-step procedure to connect the NRF24L01+ to the GPIO pins and use the Raspberry as a Serial Gateway (MySensors 1.x) " and get an error that is not mentioned (MySensor.cpp:644:5: error: ‘gettimeofday’ was not declared in this scope).
and this after sudo: /usr/local/sbin/PiGatewaySerial: command not found

i will have a good sleep and continue tomorrow

[mfalkvidd]

Nice work @goblin

Could you share all commands you ran and the entire output, including the configure, build and test steps?

Also, I don’t think Domoticz can use the gateway as a client. You should probably omit the --my-controller-ip-address=127.0.0.1 argument.

[goblin]

thanks for your response.
I tried all possible combinations but one ( the one that works)
I started with "https://www.mysensors.org/build/raspberry"
git clone https://github.com/mysensors/MySensors.git --branch master. Expected response "fatal: destination path 'MySensors' already exists and is not an empty directory"

Then i need to make a hardware choice in domoticz : between USB,LAN or MQTT.
and that is something i don't understand because non are used. The NRF24L01 is connected to MOSI MISO of the RPI.

sorry for the long Reply

I am missing mysgw

I have searched the whole sdcard with WINSCP but can't find the config file, should be in /etc/mysensors.conf.

[mfalkvidd]

The key is here:

hal/architecture/Linux/drivers/core/interrupt.cpp:33:10: fatal error: stropts.h: No such file or directory
33 | #include <stropts.h>
| ^~~~~~~~~~~
compilation terminated.
make: *** [Makefile:99: build/hal/architecture/Linux/drivers/core/interrupt.o] Error 1

See https://forum.mysensors.org/topic/11138/mysensors-build-problem-on-ubuntu-20-04-rpi-or-tinker-board/2 for a possible workaround. Then restart from the make step.

Mysgw will only be created after successful make.

[goblin]

thanks for pointing this out .
i have added a empty file stropts.h with sudo touch stropts.h. in the dir : usr/include
then Build make
a lot of response with a lot of warnings but 1 error at the end
(last lines )
/usr/bin/ld: build/examples_linux/mysgw.o: in function .LANCHOR1': /home/pi/MySensors/./hal/architecture/Linux/drivers/core/config.h:39: multiple definition of conf'; build/hal/architecture/Linux/drivers/core/config.o:/home/pi/MySensors/hal/architecture/Linux/drivers/core/config.h:39: first defined here
collect2: error: ld returned 1 exit status
make: *** [Makefile:80: bin/mysgw] Error 1

and still no "If there were no errors during compilation the file bin/mysgw will be created"
any idea were to look for this error ?
thanks

[mfalkvidd]

The bew error you got is discussed in https://forum.mysensors.org/topic/11448/config-h-39-first-defined-here/4

Easiest way is probably to switch to the development branch of mysensors.

Run git checkout development and then start over from the configure step. Or follow the step ”To use the development version with the latest updates” on the raspberry pi gateway build page.

[goblin]

Sounds like a plan but i am just a monkey that's able to push some buttons so very little knowledge of linux.

Tried to start with the development version but it seems that the previous version has to removed.
"fatal: destination path 'MySensors' already exists and is not an empty directory".

[goblin]

it's a pitty of all the used MySensors units but i am better with hardware then software so will see if i can replace them with tasmota.
thanks for the help

[dirkju]

@goblin said in mysensors on rpi with NRF2401 with Domoticz:

fatal: destination path 'MySensors' already exists and is not an empty directory

Seems like you're trying to clone the MySensors git repo but there's already an existing MySensors folder. This is a typical git error message.

If you haven't given up yet, you could rename the Mysensors folder to something else and git-clone the development branch as advised by @mfalkvidd.

(As a general advise, if you are unsure, it might be an option to just ask ChatGPT about the error messages, describing your scenario. It knows git and Mysensors ;-))

[goblin]

thanks dirkju. have tried the ChatGPT method and used --branch development.
i haven't give up hope (yet)
MySGW is running but are stuck at the choice between MySensors Gateway with MQTT, with LAN interface or USB. although it is connected via MOSI/MISO of the RPI
So basically the configure -- ?? settings and the Domoticz hardware settings.
thank

[dirkju]

Hi goblin, so you got MySGW compiled successfully now using the development branch in git? That's great to hear! I do not have experiences with RPi gateways, neither Domoticz. But I believe choosing the Ethernet option is the easiest to configure (see Domoticz). Does that work for you?

[goblin]

i was not able to get MySensors running in domoticz but i will thing CHATgpt will help getting it to work

[dirkju]

@goblin feel free to share concrete error messages or questions. We might be able to help on well-described problems. Otherwise - hope ChatGPT can help you ;-)
