@mfalkvidd Thanks for your help! I wasn't utilizing the debug feature on the node (I had to uncomment it), but once I had that at my disposal, it was helpful to know the gateway radio was either not receiving, not acknowledging, or both. The radios I bought were the cheapest ones on amazon from a Chinese seller under the "brand" of "SongHe". The chip might be a valid (yet cloned) nrf24l01+ chip, but everything else about these boards screams fake-clone - not even any markings to identify the pins. Once I pulled one of my other radios out of another project and plugged it all in, voila - it works!! I was so happy! Thanks again!

@bsmtdweller Update to this mystery:

1. I added a 1micro farad tantalum cap right at the RX radio, which initially did not start working, but after a few minutes, did start working. Observing the radios communicate for about an hour, the RX radio would work normally for a period, then fail - not ack sending radio, then go back to working. These observations lend real credibility that these radios are RIDICULOUSLY sensitive to their power supply - at least in this use case. (my RX radio is the nrf24l01+ PA + LNA with added 470 micro farad electrolytic cap after the regulator and now the tantalum cap at the board)

2. I dont know if it is factoring into these symptoms, but it may -- I'm not using the IRQ pin, which seems to play a vital role in the radio's sleep behavior and therefor power consumption (at least as it relates to the charging of the caps) which might explain the intermittent successes. Later I will add the IRQ wire into the mix.

3. Being honest - I have been banging my head against the wall with this and wanted to give up on it many times! But perseverance does pay off -- so any of you newcomers (like me) reading this -- dont give up!!

@mfalkvidd Thank you very much! So, this whole thing is a bit wonky! But when I stopped the gw and started it again, the new sensor was picked up! What the hell. They are both being recognized by the controller now, although there are still some strange behaviors happening. But now that I have the gateway log at my disposal, I have the ability to utilize the log parser and get a better understanding of what is going on.

Thanks again @mfalkvidd, you the man! I'm sure you will hear more from me soon!

@mfalkvidd Now that I'm getting my feet wet a bit with MySensors, I would like to get your opinion on designing my first "real" project. This might be more appropriate as a new thread, but I will share my objective and follow your advice for either moving it or re-starting it somewhere else (general discussion?)

The idea is that I have a box, consider it an incubator, where I will need to maintain 80 degrees or so and 50-60% humidity. There will be 3 computer cooling fans to circulate and bring in cool air when too warm, a 110V mini space heater to add heat when its too cool, 2 servo arms to open ventilation gates based on a schedule and if it is too warm, and a solenoid valve to control a gravity drip system (supplied by a bucket of water outside the box) to maintain the humidity. There will be a 16x2 lcd keypad shield used with a simple menu to adjust setpoints and display temp humidity at the box.

If it were a standalone arduino project, I would be fine - or at least muddle through it to functionality, but I would like to be able to monitor and adjust temp/humidity setpoints through domoticz. The important thing is that the box not rely on the domoticz controller, but rather work with it and when the gateway is down, the program runs its course.

So from a design perspective, do I plan to code using MySensors and squeeze in the standalone functionality, or vice versa? Also, is it easier/better to have multiple nodes for this project, or can a single node handle what will equate to 2 sensors, and 7 relays.

Perhaps you know of some other threads that might be similar?

Thanks so much for your input!!

@mfalkvidd Please forgive my newness, but I'm not sure where to do what with those instructions. I've been playing with arduino for a couple years, but this is my first go round with raspberry pi. So the configuration file is accessible how? I see it is stated that the path is /etc/mysensors.conf but how do I manipulate it? Is it from the base prompt (pi@raspberrypi:~ $ )? Or from pi@raspberrypi:~/MySensors $ .

I entered all the commands for each type in the base prompt, then restarted the pi, but how can I view the log in the first option?

In the second option, this is the output:

pi@raspberrypi:~ $ tail -f /var/log/syslog

And finally, the 3rd method must not have been performed properly, because it returns:

Thank you for your patience!! & Willingness to help!

@mfalkvidd The radio is out in the open, I've tried holding it up and in different orientations as well as touching the rx antenna. The Domoticz log only shows the original node as connected, it doesn't see the new node. Is there a way to see more detailed output directly from the raspberry pi regarding what it happening with the gateway radio?

@bsmtdweller Next challenge with this project:

I'm trying to connect another node now, the first one is humming along with no issues at all. The new node is a arduino nano running the DHT temp sketch. Smaller NRF24 is the radio and powered by an external wall wort --> into regulator --> into a 230 mic farad cap, then a .1 mic farad tantalum --> into radio. This is the second radio I've tried and the symptoms are the same - radio sends message ok, but FPAR fails - much like when I set up the gateway radio. But the 1st node is running fine on through the gw. I've cleared the nodes eeprom, and ran the sketch that @mfalkvidd posted back in 2016 to set a new node ID. Heres a little of the output from the node. Am I supposed to be posting the output this way? or is there a better/preferred way? Thanks for the help!

@bsmtdweller Another update:

Im beginning to think these radios suck! But alas, give them what they want and they do work! This configuration is: power comes from Raspberry Pi 4 (5v) fed into a small voltage regulator then on to the 'solution' -- premium low-ESR capacitors (1) 470 mic farad followed by a 230 mic farad right before the radio. Also, twisted wires between the reg and radio and the radio was rewired where the wires (not dupont jumper wires anymore, but 24ga silicone wires) soldered right to the board. I also crimped new ends on the communication wires connected to the Pi pins.

So far so good! Most successful concurrent transmissions so far! And no loss of communication yet! I'm thrilled! Now on to how to cram all those capacitors into the fancy enclosure I printed out - ugh.

1. I added a 1micro farad tantalum cap right at the RX radio, which initially did not start working, but after a few minutes, did start working.

@mfalkvidd My excitement was short lived. It did work, for a little while, but then stopped and went back into the loop of not being able to find the parent. I've gone through the troubleshooting flowchart a dozen times now and done everything I can given my limited debugging skill. I've replaced both radios, re-wired both radios, both radios have capacitors, moved them closer together/further apart, tried using separate power supplies for both radios, deleted an re-installed the MySensors dir and gateway, deleted and reinstalled Domoticz.

In the troubleshooting flowchart, one of the boxes is 'debugging the controller/gateway' - is there some nifty unix command that might shed some light on this? All I have to go on is the log of the Domoticz, and it connects up fine and doesn't have any errors.

Could this be a raspberry Pi 4 issue? Or am I simply fighting the low quality chinese cloned radios? The ones Im using work great for regular arduino (non-mysensor) sketches.

Any thoughts? I appreciate any help!

I'm brand new here, and hope someone will nudge me in the right direction to figure this out. Trying to set up a Raspberry Pi 4 B as an ethernet gateway for Domoticz using a NRF24L01 + PA & LNA. I have an arduino nano clone set up as the node also using the NRF24L01+, running the DallasTemperatureSensor sketch. I have followed every link and lead I can find on this forum as well as the web and either I'm missing something fundamental, or I have a legitimate technical issue. I have Domoticz installed, running and connected to the gateway at this point, but no sensors are detected. Any help is greatly appreciated!

./configure --my-rf24-ce-pin=22 --my-rf24-cs-pin=24
(I had attempted adding a lot more option details like my-controller-ip & my-port#, but it would never connect until I slimmed the options down to just specifying the ce & cs pins with everything else at default)

here are the test results: the command prompt did not show up without stopping the output - it was in some sort of ping loop.
