Step-by-step procedure to connect the NRF24L01+ to the GPIO pins and use the Raspberry as a Serial Gateway (MySensors 1.x)

[mfalkvidd]

@shabba the best discussion I've seen so far is http://forum.mysensors.org/topic/1918/what-radio-to-use-nrf24l01-rfm69-rfm73/

[shabba]

Thanks @mfalkvidd - will check it out.

[shabba]

Ps. I followed https://github.com/abouillot/HomeAutomation/tree/master/piGateway and now have a MQTT service running. But I do not know how to connect this to domoticz or even debug that it can actually see my test sensor etc.

[stranger]

This thread has been great - thanks @mfalkvidd!

@hayduke I had a similar problem earlier. I haven't fixed it yet, but here's where I'm at:

Clean install (Jessie, RF24, Raspberry) March 25th 2016 has the problem where it works for a few minutes, then stops (/dev/pts/0 dissapears, which breaks the symbolic links - ttyMySensorsGateway and ttyUSB20). This is at home where I have a bunch of nodes around and a Vera with serial gateway, so there are lots of different signals coming in.

But when I move to another location with just one node (that just sends a light status update regularly), it works fine - at least, I've been sitting here with it running for 30 minutes so far.

I know this might not help much, I'm new to all this and still getting my head around everything. I would probably agree with what you suggested earlier: something in one of the messages that causes a problem with the gateway (possibly to do with already having another serial gateway nearby).

I'll try to do some more testing by changing this gateway to a different channel to my other one, and gradually bringing nodes across to see when it breaks.

[alexsh1]

@stranger just to make sure - you said you have two gateways at home. Did you change the channel so that they do not interfere with each other?

[Tore André Rosander]

Hello, im just starting to set up some mysensors nodes and have already set up a gateway with nodemcu (esp).
But to eliminate the number of devices i am thinking about moving the gateway directly to the Raspberry pi as mentioned in this thread. Is there any downsides (or upsides) by connecting the nrf24 chip directly to the RPI?

And btw:
"The radio module NRF24L01+ is cheap and power efficient, but it is unable to communicate with regular wifi."
That is not entirely correct, the nrf24 can connecct to wifi and send TCP/IP packets with an arduino.

[stranger]

@alexsh1 No actually. I didn't want to go around and reprogram all my nodes, and I forgot to turn off my other gateway. That is what I was going to do next, but I've just been running it for a few hours with no problems (with a heap of nodes and another gateway a few metres away, all on the same channel).

I then Home Assistant and tested out a few nodes, and now it sometimes breaks, but mostly works fine.

All that being said, I've realised I need signing (I have a few electronic locks), so I'm going back to a hardware serial gateway. If anyone has got signing working I'd love to hear how - I had a look but couldn't figure it out and don't have much time to spare on it.

Playing with a RPI 3 B and a NRF24+ radio I got this error message above.
Running Jessie but with no luck...

Anybody else got this problem?

[mfalkvidd]

@Sander-Stolk did you run

sudo make install

?
What happens if you run

sudo /usr/local/sbin/PiGatewaySerial

?

[Sander Stolk]

@mfalkvidd
Tnx that worked but this is not in the tutorial I'm I right?

If this happens, double-check your wiring and correct any problems. Press Ctrl+Z and type

sudo killall PiGatewaySerial
to get rid of the non-functioning Gateway. Then run sudo /usr/local/sbin/PiGatewaySerial again

If all is well, exit PiGatewaySerial by pressing Ctrl+C. Then run

sudo /etc/init.d/PiGatewaySerial start
to start the gateway as a background process. Verify that it started correctly by running```

[mfalkvidd]

Yes it is. See the section under
COMPILING THE GATEWAY

also, you ran sudo ./PiGatewaySerial instead of sudo /usr/local/sbin/PiGatewaySerial described in the instructions.

[mfalkvidd]

I have added a
TROUBLESHOOTING
section in the original post to cover for this error. Hopefully it can help if someone else makes the same mistake.

[micah]

Any thoughts on making a version for the 2.0 dev branch?

I recently switched my in-progress builds to 2.0 and am in the process of "trying" to get my Raspberry Pi2 setup with OpenHab and Mosquito. And the idea of not having to have an ethernet gateway arduino in the mix is appealing to me.

I would do it myself but I probably only have 3.275% of the required knowledge at this point

[mfalkvidd]

I'm unfortunately at about the same level as you. I can compile stuff and do basic troubleshooting, but merging the dev branch with the gateway code is way out of my league.

There is no way you are at 3.275% knowledge like me... I've seen many of your posts on here and you are at least a 4.532%... lol.... no honestly I've liked your posts and you seem very knowledgeable. You've got to be at least a 84.5%

[Sander Stolk]

Can somebody tell me how to change the channel after compiling and using the Gateway for a couple of days?
Changing the channel in MyConfig.h in the dir Raspberry doesnt bother even after a reboot.
Still 0x4c channel / 76 when I run the PiSerialGateway program.

Did you recompile the code after changing the channel?

[Sander Stolk]

@alexsh1 I did this after changeing the channel in MyConfig.h: make all && sudo make install
Rebooted after that but no luck

[mfalkvidd]

That should be sufficient but you could see if running make clean before make all helps.

[Sander Stolk]

@mfalkvidd I did the make clean and the make install and rebooted.
Still 0x4c eq. 76

@Sander-Stolk I don't see a new make install in your output. Did you miss that or is the output just not included?

make all compiles the code. The result is a binary file in the Raspberry folder
make install copies the binary (and some scripts I think) from the Raspberry folder to the system folders.

[Sander Stolk]

Ok here's the deal to change the channel or other settings:

cd Raspberry
make clean
make all
sudo make install
Done!

Hi, is signing supported using this library? thanks.

@cingolanifede the Raspberry Pi gateway does not support signing.

[BikeDan]

I'm looking for some help in getting "PiGatewaySerial" running properly. I am having no issue running "PiGateway" and receiving all data from a counter node I'm using for testing. When I try to run "PiGatewaySerial", only intermittent data appears. For this example, I have my counter sending increasing integers at 1 second intervals, and receives fewer than 1 in 25 through the "PiGatewaySerial" script. I previously had this working reliably on a RPi2, reading in the tty output and logging it to a file. Now, I cannot repeat that on either that device, nor the current RPi B+ I'm working with. I'm sure there's some basic setting that I'm missing, but I can't seem to figure it out. Thanks!

I'm running a RPi B+, NRF24l01+, on a clean install of Jessie, and using only a few percent of the CPU power.

[rmtucker]

I have been thinking about giving this a try But:-
The Raspberry port is using protocol version 1.4.
Do the sensors also have to use version 1.4?

[GertSanders]

@rmtucker
No, the sensors can be running 1.5 or 2.0-beta, the PI will run a 1.4 version.
The only thing not supported by the PiGateway is message signing.
But I have a mix of sensors in 1.5, 1.6-beta and 2.0-beta in my home network, so it certainly works.

[rmtucker]

@GertSanders

Is it best to start with a blank jessie image and manually install/compile domoticz or just use the domoticz sd image?
The latter would be the easiest for me because i am useless with the CLI but if the first method is best??

[Anticimex]

Adding support for signing on a pi gw should just be a matter of implementing random number generation and use software signing. With slight modification in the software signing backend as it assumes Arduino api:s for obtaining a seed for the rng.

[mfalkvidd]

@rmtucker if you want to be able to run the very latest version of Domoticz, use the Debian image and compile Domoticz from git.

I use the Domoticz image. The downside is that I need to wait for new "official" Domoticz builds before upgrading, but the upside is that getting up and running was very easy.

[GertSanders]

@mfalkvidd
Actually ... I started with an official Domoticz build, and then I indicated in the settings that I wanted to update with the beta version. Since then I'm always on the latest beta (v5143 at the moment).

[mfalkvidd]

@GertSanders cool. How often is the beta updated? Every build?

[rmtucker]

Just set this up on my existing Raspberry pi B+ Domoticz server and it is working perfectly so i have managed to get rid of the uno Gateway.
Thank you so much,I can now try and squeeze it all in the Raspi case and the job is finished.

[rmtucker]

This is the cpu usage,the spike is me compiling the software as above.

[GertSanders]

@mfalkvidd
Well, that seems to be the case. Sometimes I see daily updates, sometimes a week passes by without any changes. I selected the BETA channel for updates and since then I have seen new functionality come in on a regular basis. Not all of it is relevant to Mysensors of course, but none the less it's fun to see Domoticz is developed actively.

[wergeld]

@GertSanders I have seen no issues in Domoticz stable with CPU usage. Thing just purrs along. Will have to check when I get home but i believe my system uptime is approaching 1 year. It "just works" as they say.

I would like to upgrade to mysensors 2.0 library by it looks like the Pi repo has not being updated as often (last I checked, anyway).

[GertSanders]

@wergeld
Correct, the PI repo is basically unchanged. But it still is compatible with the 2.0-beta Mysensors library.

[wergeld]

@GertSanders What? I was under the impression that some features (like sending messages to nodes from domitcz wouldn't work).

[GertSanders]

@wergeld
Did not notice that, I can send values and "switch on" messages to nodes. The only thing I miss is the signing via ATSHA204. Even V_TEXT sending to and from nodes works.

[Tore André Rosander]

I have some trouble with the gateway not storing the network map, if i restart the gateway my non-sensor nodes need to send some kind of heartbeat to reconnect to the gateway.

Is this a known problem or is it something wrong with my setup?

[hek]

Yes, known problem.

I had some hopes on @marceloaqno and @aaron832 providing a PR into development branch (so we can scrap the old RPI code). But there hasn't been any activity in a while.
https://forum.mysensors.org/topic/2759/mysensors-raspberry-port-suggestions/12

[Tore André Rosander]

@hek But insted of including heartbeats from every non sensor node (trying to keep 2.4 ghz traffic to a minimum), can i solve this by using an arduino repeater node? So the repeater knows the network map and sends heartbeat to the gateway.

[hek]

@Tore-André-Rosander

No, not possible. The repeater won't propagate it's knowledge about all sub-nodes.

[jpbabou]

@Sander-Stolk hi
how do you achieve to have a nice 'logon' screen ou your PI: Domotics Logo, @ip,memory,date... etc etc..
Im' newbee on raspberry from france
HAve a nice day
JP
i really want to have the same or any available sample like yours

I have been struggeling with this for some time now. It seems my compiler is not the standard for raspberry pi? (I have a pi 2). I have used the domoticz sdcard as ground for my system and it works (a bit sketchy with random freezes and I cannot access the domotics webserver from chrome) but still. Anyway, I get stuck on making the RF24 package. Any ideas?

pi@raspberrypi ~/RF24 $ make all && sudo make install
arm-linux-gnueabihf-g++ -fPIC -march=armv7-a -mtune=cortex-a7 -mfpu=neon-vfpv4 -mfloat-abi=hard -Ofast -Wall -pthread  -c RF24.cpp

[alexsh1]

Did anyone setup rfm69 successfully on the raspberry pi

[GertSanders]

Has anyone used the Raspberry GW software in combination with nodes that run the new 2.0.0 MySensors code ?

[tbowmo]

@GertSanders

It's not supported, 2.0.0 nodes require a 2.0.0 GW. And the raspberry pi port is not updated to 2.0.0 (and unfortunately there is currently no one in the core group that uses the rpi gw.. We all use serial / ethernet gw's of some sort)

[GertSanders]

@tbowmo
I was afraid of that. In my enthusiasm I updated to 2.0.0, but now my new nodes play dead.
At least I know why.
Time to make that old ethernet gateway functional again.
Since Breda meetup is this weekend, I will have no more time to figure this out (if I could ever, this is UNIX). Maybe after I can try something.

[wergeld]

@tbowmo

What would be required to get the RPi gateway up and running? Having single controller/gateway is great.

[GertSanders]

@tbowmo
Is a 2.0.0 based gateway backward compatible with nodes in an older version ?

[GertSanders]

@wergeld
Probably porting the Arduino lib to Raspberry and compiling again ?

[GertSanders]

@tbowmo
Is the last 2.0.0-dev version (before the new 2.0.0 official release) still available somewhere ?
That DEV version seemed to still work with my Raspi GW.

[wergeld]

@GertSanders

Time to start reading up on converting the lib! Might have a go at it in week or so. Work is holding me hostage at the moment.

[GertSanders]

Praise Apple for making TimeMachine. I was able to set back the last version of MySensors lib I know was working with my gateway in a bout 1 minute.

Back in business now. Upgrading the gateway and nodes to full 2.0.0 is for later.

[tbowmo]

@wergeld

you need to port the mysensors core library.. It is however filled with arduino specifics at the moment (we have had some talks about removing arduino dependencies, but it's not made yet).

Ideally someone should make a raspberry pi port, that we can merge into the main repository, so the same codebase can be build for both raspberryPi and arduino based hardware.

@GertSanders

A 2.0.0 GW should be compatible with 1.5.x nodes, but 2.0.0 nodes require a 2.0.0 GW.. (I can't remember the specifics in what the changes are, @tekka is the brain behind that stuff). That said, we do recommend that both nodes and GW will be updated to same mysensors versions, as to avoid any problems.

[mfalkvidd]

@tbowmo @wergeld @GertSanders a port is already available, see https://forum.mysensors.org/topic/2759/mysensors-raspberry-port-suggestions/11 (and github)

It would be awesome if someone could merge that great work with the MySensors repo.

[tbowmo]

@mfalkvidd

Ok, didn't know that it was updated to 2.0.0 "final", thanks for the hint

[Sander Teunissen]

Would it be safe to say a RPI gateway 2.0 is not available yet for beginners ? (like the instructions @mfalkvidd made are not usable for this ?)

[GertSanders]

@Sander-Teunissen
At the moment I would advise beginners to use a separate GW for the official 2.0.0 (ethernet or serial based). I found the ethernet based gateway the easiest to use in various setups, espcially since Domoticz (my controller of choice) supported this.

[Sander Teunissen]

@GertSanders Thanks Gert !
I did a quick build of the serial gateway using an arduino which I connect to my RPI. Pretty easy. I'll be watching this when I can switch back to the RPI built gateway...

[flopp]

@mfalkvidd said:

OTHER NOTES

• The 3.3V power on the Raspberry Pi is rated for a maximum of 50mA. A regular NRF24L01+ only needs 15mA, but if you are using a power amplified version you might exceed what the Raspberry Pi can output. In that case, an external power supply might be required.

Nice guide thanks.
when using external power supply i think it is best to connect Ground from Rpi and ext power supply. Maybe write that in the guide?

[alexsh1]

@flopp the best would be to use Raspberry's 5V rail and reduce it to 3.3V via the LDO like @GertSanders did in his board.

There is one member using 3.3V rail for powering PA+LNA Tranceiver without any issues - check out the latest open hardware. I have not tried it personally

[mfalkvidd]

@alexsh1 I wouldn't want a guide to recommend a solution that is way outside the specifications even if users might not experience problems. Strange problems usually happen outside specs, they are a pain to troubleshoot and in this case might lead to frying someone's Raspberry Pi.

@flopp thanks for your suggestion, I've amended to guide.

[SeanMarsh]

@mfalkvidd I"m confused. I noticed the instructions below is for 1.5X or below and will not work with 2.0. The link for 2.0 that is posted doesn't make any sense to me at all. It also takes me to a thread where I start reading the information from the middle of a thread. I'm coming to the conclusion that it doesn't work yet..... Am I right?
SUPER New here. sorry

[mfalkvidd]

@SeanMarsh I don't know anything more than what's stated in that thread, sorry. That's also why it is the last option of the alternatives. Go with a serial, wifi or ethernet gateway if you can.

[tlpeter]

I also have a serial gateway next to my raspberry (3 in this case) with Domoticz on it.
If there is an issue than at least a part is still running without breaking everything.
I am using zwave at most and mysensors now for playing.
I cannot break the current zwave implementation so for me a serial gateway is the best solution.
For playing around you might just try as i imaging it could be fun to do it.

[wergeld]

How can we update the gateway to v1.5? I just tried to rebuild from github today and I am getting really odd errors now that I did not get before:
cc1: error: bad value (cortex-a7)

What I could find online states I need to update the gcc compiler on my rPi - it is currently version 4 and latest is 5...but apt-get update gcc says I am already at latest version.

I am trying to get my slimNodes up and running using v1.5 of mysensors.

[Toyman]

How can I use "PA power HIGH" with this setup?

[Reza]

i can not add device to domoticz controller with serial gateway(1.4)

MySensors Gateway USB
Version: 1.4 Setup

[Reza]

is this true ?

pi@raspberrypi:~$ sudo make enable-gwserial
make: *** No rule to make target 'enable-gwserial'.  Stop.

[Toyman]

@Reza try:
cd Raspberry
sudo make enable-gwserial

[Reza]

@Toyman
thank you

[Reza]

in domoticz i have this problem :

pi@raspberrypi:~$ sudo cat /dev/ttyMySensorsGateway
cat: /dev/ttyMySensorsGateway: No such file or directory

[rmtucker]

How do I remove all that I have installed at the top of this thread so I can revert back to an arduino serial gateway?

[mfalkvidd]

@rmtucker run "sudo make uninstall" when standing in the Raspberry folder

[rmtucker]

@mfalkvidd do you mean the root directory?
I have had this running for a number of months but I want to go back to the arduino serial setup without losing my domoticz controller or data.

[mfalkvidd]

@rmtucker I mean the folder containing the files from the git repo.

[Toyman]

Is there a way to manually type messages to the nodes?

[_Rooky_]

Hi,
maybe someone could give me a hint. I installed everything and it looks like it is working, but no sensors are displayed in Domoticz. Any idea what's wrong?

I used this sensor before with a ESP Wifi gateway and it was working fine. The DallasTemp Sensors got visible in Domoticz right after the gateway was added in the Hardware section.

After installing the NRF24l01 on the Rasperry Pi 3 and follwing the instructions above, I added MySensorsGateway USB with /dev/ttyUSB20, but nothing happend.

Would be nice, if I could get this smart thing working. Else I would need to go back to the ESP Wifi gateway.

[mfalkvidd]

@_Rooky_ congratulations on your first post in the forum, welcome!

The gateway uses MySensors 1.4 and the node uses version 2. These versions are not compatible.

You probably want to use version 2 for the gateway as well. https://www.mysensors.org/build/raspberry describes how to create a gateway for version 2 (the gateway was completely rewritten for version 2)

[_Rooky_]

@mfalkvidd many thanks for the very quick and polite reply.
It is working now and this solution is much better way, than using an additional ESP as gateway.
Even though I got on the wrong lane, I learned more details from your excellent guide, than from the "make", "make install" from the MySensors page ... and still got a lot to learn

[ronnyandre]

Thanks for this thorough guide, it works perfect

[ronnyandre]

@Scala I have the same error as you. Worked perfectly first time, and after reboot the "/dev/ttyMySensorsGateway: No such file or directory" error message appear. Did you solve this?

@MrRikkie Did you solve this issue? I got the same error as you..

I know this thread is ancient, but why it was needed to add

to

TTY_NAME := /dev/ttyUSB20

and create "proper" name from the start

Hi,
I plan using a gateway with Mydomoticz and this solution seems great. However, I might want to use later signing or the high Amplifier NRF24 or even the version 2 which seem not suitable for this project.
How easy is it to start with this gateway, then migrate to an external ethernet gateway ?
I saw this gateway can be uninstalled, but should I then modify anything on sensors to move them to new gateway ? will I lose log datas in Domoticz ?

br,

@ricorico94 welcome to the MySensors commu ity! All you need to do when switching from raspberry pi gateway to ethernet gateway is change the "hardware" configuration in Domoticz.

However, if you are just starting out, don't use this gateway. It works for MySensors 1.x only. Use the new raspberry pi gateway instead.
