so i took a good look but mostly i found your recommendation for the ebyte modules.
are we talking about this one? https://it.aliexpress.com/item/CDEBYTE-2PCS-Lot-E01-ML01D-Wireless-Transceiver-For-Arduino-nRF24L01-2-4GHz-Antenna-Module-For-Microcontroll/32803704874.html?aff_platform=aaf&cpt=1542663609771&sk=cMM8rUbm&aff_trace_key=1fc52e06d7a94d0096aabebefb8bb607-1542663609771-06798-cMM8rUbm&terminal_id=f538d8e92d1f481098e725b32d788ce6

cd-ebyte?
i won't need a stabiliser for the Sensebender Micro board, right? on every build i found a radio connected directly mounted on the board...

Sorry for the bis confusion...

E01-ML01D SPI nRF24L01P 2.4Ghz 1mW PCB Antenna IoT uhf Wireless Transceiver nRF24L01+ Transmitter Receiver Module

$3.23

thanks @alowhum !
so i'll just need 1 (one) like this for my gateway http://s.click.aliexpress.com/e/c4CU7enO ?
could you post (pm) me an example for a "red eByte module" (your link for "nano wireless board" leads to searchpage for "nrf24l01 ebyte" - but they are all green...)? i usually have to wait ~60 days until i get my aliexpress orderer items, so i really would like to get the "right one" with my first order...

and what's up with the nano wireless board?

Hello!
i was finally able to set up the gateway and some Sensebender Micro. But as i moved the nodes to different rooms i noticed that the gateway has very poor coverage
i used a Raspberry (1) with these components:
https://it.gearbest.com/transmitters-receivers-module/pp_453011.html
https://www.amazon.it/dp/B016BAPC0K/ref=pe_386201_41597321_TE_item

The Sensebender Micro is equipped with only NRF24L01 Radio.

What could i do to improve the gateways range? would NRF24L01 modules with antennas (f.e.: these) perform better or should i go with RFM69?

cheers!
Peter

alright! now with new programmer a was able to upload the "standard" sketch to my sensebender micro and the gateway even gets "something":

is this right? and if so, how can i translate all this stuff?

ohhhhhhh. this makes sense:

[20:17:18] openhabian@openHABianPi:~$ mosquitto_sub -t mysensors-out/#
22.3
61

cool cool. now i just have to figure out how to define my items on the openhab part!
cheers

oh boi. had to connect the radio to the board mentioned in the opening post:

and connect the other boards to my raspberry... now it seems to work! unfortunately i can't test it because i'm not able to upload anything to my Sensebender Micro boards. now i'm waiting for my new ftdi programmer

here's the wiring. i checked 3 times and now i rewired again with another nrf24 module - error remains the same:

Hello!
I just tried to set up a raspberry gateway according to this https://www.mysensors.org/build/raspberry .
(on raspberry1). everything went smooth, but somehow it's not working:

pi@MysensorPi:~/MySensors $ ./configure --my-gateway=mqtt --my-controller-ip-address=127.0.0.1 --my-mqtt-publish-topic-prefix=mysensors-out --my-mqtt-subscribe-topic-prefix=mysensors-in --my-mqtt-client-id=mygateway1

Nov 10 22:35:30 DEBUG TSF:TDI:TSL

so now on i should ask here
i used one of these radios (recomendation from @gohan in 2017 :)): https://gearbest.com/transmitters-receivers-module/pp_453011.html and connected it accordingly (except i used 5v pin for VCC)
first of all i don't understand why it's not working when there were just top c&p a few lines?

an then i'm not really sure in general what i need to do. what i WANT to do:
sensors > raspberry pi gateway > openhab controller
mosquitto is running on my openhab installation, so mqtt would be ok. i searched for a while, but i couldn't find anything noob-proved...

okay
i'll take a look around, hopefully i can get a few somewhere.
does the log indicate that there's a problem with radio? (length?)

the gateway "log" is some posts above.

should i provide another log?

i didn't use any capacitors, neither gateway, nor node.
here isn't anything regarding capacitors.
and [here](lhttps://www.mysensors.org/build/raspberry under section "NRF24L01+ Radio" it only says "If you are using the nrf24 PA/LNA version you need to use a 5V->3.3V regulator.", but i'm using these so i thought it's ok without using regulators.
or is a regulator something different than a capacitor?

ok, thought this would be auto assigned: "Define a static node address, remove if you want auto address assignment"
new debug: everything ok with this sensor?
debug

Next Stop Gateway? Should i just try another radio?
