Doesn't the provided init script in the library already have logging? I didn't get around to testing this setup after my initial attempt failed, so I might be wrong.

https://github.com/mysensors/Raspberry/blob/master/initscripts/PiGatewaySerial

Ugh! Correct. Also, @mfalkvidd did cover this with his "MAKE THE GATEWAY AUTOSTART" section.....If I only could read! I will test this soon to see how the logging works.

Finally, by enabling ser2net and adding something like this to /etc/ser2net.conf:

5003:raw:600/dev/ttyMySensorsGateway

....you have yourself an Ethernet Gateway! Great stuff! Thanks again!

This is a very good work !

Is there anything in place for RFM69 ? Would it be difficult to port the code from arduino to rpi ? (I have never coded on RPI).

Also, do you think any performance difference is involved in managing the radio directly from the RPI, compared to having a dedicated atmega/arduino ? Especially if a controller solution is already running on it?

I've got no experience myself with rfm69 yet, but I've been thinking about it and searching the web says it should work, connecting the rfm69 to the raspberry pi, for example here:
https://github.com/abouillot/HomeAutomation/tree/master/piGateway

There are also custom pcbs for simplicity, don't know if it's tested though:

[soward]

Perhaps re-word the last note from:

A user experienced data transfer compare to USB-to-Serial(ttl)<-->MySensors Gateway connection. especially on OTA firmware update. If you think this will cause a problem for you, an ethernet gateway might be a better alternative.

to:

A user notes that data transfer speeds are comparable to that of a USB-to-Serial(ttl)<-->MySensors Gateway connections. If you think this may be an issue for your application (e.g. OTA firmware updates), an ethernet gateway might be a better alternative.

thanx,

@soward that wasn't quite the feedback I got, but what I wrote didn't make much sense either so I have corrected it now. Thanks!

[minscof]

I have a trouble with CPU utilization when I start the gateway : 100% all the time. I use Jessie and not Wheezy on a RPI 2. Does someone can help me to troubleshoot this problem ? I have not add a decoupling capacitor , can it be the reason ?

Solved : see this post

This happened to me as well, I mixed up the boards I had at home and discover later it was a B+ and not a RPI2 Maybe you've made the same mistake?

[mfalkvidd]

@minscof got an answer in this thread: http://forum.mysensors.org/topic/2367/pigatewayserial-using-interrupts/3
The high cpu usage will go away as soon as you start your controller (or something else that reads from the tty the gateway creates).

[Eawo]

Is it possible to use NRF24L01+PA+LNA Antenna version or is it to power hungry? Do i have to change something in the code?

[georgep56]

@Eawo If you look at the excellent original post from @mfalkvidd above:

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.

I don't believe that you will need to make any changes to code.

[Eawo]

My friend also started with mysensors and i gave him my old raspberry with the 26 pin gpio. Can he also use this guide? Also if it possible how do u wire it? Im just a beginner so i ask stupid questions. maybe serial gateway is the way to go but we are waiting for arduino's

[mfalkvidd]

@Eawo Yes, it should work. I ran Domoticz and MySensors Gateway on my Raspberry Pi 1 when I first tried MySensors. If I remember correctly I had to connect CE to pin 15 instead of 22 but I am not sure why. Try using the same connections as on your Raspberry Pi 2 first, and switch CE pin if you get "check wires". Please report back here how it goes, so I can add the necessary information to the original post.

from 'PiGatewaySerial' but no results on the Serial Port. Any idea what i'm doing wrong?

[Oitzu]

Somehow the node thought it is node id 194 and a repeater...
I hacked in node id 0 and it worked. But it even works slower then the arduino serial gateway.

[mfalkvidd]

In http://forum.mysensors.org/topic/2305/nrf24l01-rpi2-direct-connection-problem/1 an user also got node id 194. Maybe the discussion there can help?

The 100% cpu usage is probably due to the style of receiving new messages from rf24/serial port.
The current state is that the PiSerialGateway tries to poll data in a endless loop from rf24/serial.
This could maybe fixed with using the interrupt of the nrf24l01+ to signal new data and reading data from the serial in blocking mode.
I want to solve this but using interrupts on the RPi isn't that trivial.

[mfalkvidd]

http://forum.mysensors.org/topic/2367/pigatewayserial-using-interrupts/2 has information on how to use interrupts. I haven't tried it myself though.

Hi all,
I'm following this thread and have upgraded to MySensors v1.5 and get the following error. Version mismatch.

It looks like the Protocol version is 1.4.

Does the Raspberry MySensors Gateway support v1.5 or only v1.4? Any ideas on how to fix?

Up until now, MySensors v1.4 only for nrf24l01+ direct connection.
Did you upgrade the GW or the sensors or both ?

[hek]

Protocol version hasn't changed since 1.4
https://github.com/mysensors/Raspberry/blob/master/MyMessage.h#L41

So you must have some other problem.. As you can see you only get zeroes in the log...

[GertSanders]

You can "fake" a later version (e.g, 1.5) on the Raspberry by changing the version code in the version.h file and recompiling the Gateway software.

As far as I understand, the gateway will still pass the messages to the controller, even is there is a version mismatch message on the console.

[den2k]

@alexsh1 I know the sensors are on v1.5. As for the Raspberry Gateway, it looks like based on the info here, that is running v1.4.

[den2k]

@hek I'm running a custom 1Mhz build bootloader on a Pro Mini for the Sensor side. This was paired with the standard Serial Gateway running on another Pro Mini with v1.5 on both gateway and sensor. That setup was working. But I moved over to using the Pi gatway+nRF24+ radio and have this issue. I don't believe the hookup is the problem. I've seen the 0 readings before, and that usually meant node side issue or uninitiated Gateway. I have not changed the Node, so it must be the Pi gateway that is the problem. Any thoughts on what to test?

[den2k]

Noob question. Any one have an idea on solving the "Permission denied" error.

[den2k]

Solved my own problem. Using the following command did the trick.

sudo chown -h pi:pi ttyUSB20

[den2k]

weird. Permission Denied problem again.

What is the USER : GROUP that is needed for this to work?

[mfalkvidd]

@den2k I think your best chance is to post in the Home Assistant category. I don't have any experience with Home Assistant unfortunately.

@den2k

Hi!

Have you added the user that runs homeassistant to the dialout group? This group is usually owner of serial ports.

Check default group of serial port (change for your port below) after connecting it:

pi@martin-pi:~ $ ls -l /dev/ttyUSB0 
crw-rw---- 1 root dialout 188, 0 dec 18 03:21 /dev/ttyUSB0

Check groups that user pi is in:

pi@martin-pi:~ $ groups pi
pi : pi adm dialout cdrom sudo audio video plugdev games users input netdev spi i2c gpio

If pi runs homeassistant, which should be the case, and is not in dialout, add pi to dialout:

sudo adduser pi dialout

Changing owner of a port will only work until you disconnect it. Default owner will be restored upon reconnect, if you haven't written a special udev rule.

Edit:
According to the readme in the mysensors raspberry repo (https://github.com/mysensors/Raspberry), the group of the device is tty. So you should probably use that, and not dialout. But you will know, when you check with ls -l.

Southern regards and happy new year to all!

[mfalkvidd]

You are using a sensor type that your version of Domoticz doesn't support. What type os sensor is it? Which version of Domoticz are you using? Upgrading Domoticz might solve the problem (if the newer version supports this sub-type).

[martinhjelmare]

@Sander-Teunissen

Try writing a udev rule to set owner of the device (ttyMysensorsGateway) at boot. If you don't need to use the link you could write a rule that names the pts device to the same name every boot, I think. At least for usb devices this works. Haven't tried it in this particular case.

The permissions for a soft link are not used (and if they were, any user would be allowed to do anything since everything is rwx). The permissions for the target is used instead. So it is the result of

ls -l /dev/pts/0

you need to worry about.

[ahmedadelhosni]

Hello @mfalkvidd , I read the topic again but I am a bit confused. Normally we have a sketch on the Arduino board to enable signing for example or implement our desired code. I don't understand how to edit this before compiling ?

[mfalkvidd]

Sorry @ahmedadelhosni, I haven't tried to compile the Raspberry gateway for signing. @Anticimex will probably chide me for that, and rightly so
It should just be a matter of modifying MyConfig.h to enable signing, as per the instructions in http://forum.mysensors.org/topic/1021/security-introducing-signing-support-to-mysensors but maybe the MySensor files in the Raspberry repo haven't been updated with the signing features.

[Anticimex]

The signing backends are updated for multi arch support thanks to @tbowmo and his SAMD gateway project, but they still assume Arduino compatible api:s for io, so if the raspberry repo/port provide that, it should work. If not, it should just be a matter of adding support for the raspberry spi:s for setting pin direction and states and (if sw backend is to be used) provide a random number generator. The code is C/C++ and hw independent in other aspects.

[Anticimex]

If anyone would like to add support for rPi to the signing backends, I suggest using a Linux generic approach using sysfs to handle io. Same for rng (using an appropriate device node, rpi has a hw rng that should be used).
If the design is Linux generic and uses proper design to abstract raspberry board specifics, it opens up for reuse by any hw that uses a Linux kernel

[hayduke]

I've been struggling with this setup for a few weeks now. I've resisted posting to try and figure it out, but I'm not making any progress. When I first setup the rpi with the nrf24 directly connected, everything worked great. I was running a node with temp and motion pretty reliably. I had some difficulty getting the relay node to work, but I got that working eventually as well, but not reliably. While trying to resolve this, I started getting these errors (log from Domoticz):
2016-02-19 10:43:36.007 MySensors: Using serial port: /dev/ttyUSB20
2016-02-19 10:43:36.008 Error: MySensors: Error opening serial port!
2016-02-19 10:43:37.008 MySensors: retrying in 30 seconds...

I see the post above about this being related to using sensors not supported. Since it started with the relay node, I took that out of the setup, but I'm still getting the error.

I've rebuilt the entire rpi, mysensors, and domoticz, but I can't get it to work reliably. If I start the gateway manually via a putty session, it will work for a few minutes, but then it stops and goes back to the command prompt in putty and I can see the log in Domoticz start showing the above errors.

I have setup the gateway to start automatically, but it doesn't seem to restart correctly after a reboot.

I suspect I have a version mismatch in my code somewhere, but I can't seem to find it. My last effort was to remove all code from my computer and start over, ie reinstall Arduino and a fresh download of MySensors code (v1.5).

I've also tried changing the permissions on the tty devices, but that didn't seem to help either.

I was real excited about this project when I first read about it. When I finally got some parts in, I had some quick success that kept me motivated, but my enthusiasm is waning a bit with my total lack of progress on this issue.

Thanks in advance for any help.

[mfalkvidd]

Which capacitor(s) are you using?
Do you use a power amplified version of the nrf24l01+ or the regular version?
What is the output of /usr/local/sbin/PiGatewaySerial until the gateway stops working?

[hayduke]

@mfalkvidd
I have a 4.7uf electrolytic cap soldered directly to the pins on the radio module.
Radio is standard, ie antenna via board traces.

I just did another batch of testing to try and answer your last question.
I started the gateway manually, ie sudo /usr/local/sbin/PiGatewaySerial
I plugged in a temp sensor (dallas 18b20, 3.3v apm, via 3.3v FTDI) into the computer so I could monitor the serial port.

The first time I turned on the temp sensor, the gateway closed after 5 "read:"'s. I tried it again and the gateway stopped (meaning I was back at the prompt in putty) after 2 reads.
I decided to reboot the rpi. When it came back up, I had the Domoticz log open and I could see the gateway start before I could reopen a putty session. It appears the auto start worked correctly, and so far, it's still up.
I've been sending temp data successfully for ~10 minutes now.

...time passes...
I typed out the above, but didn't hit submit as I wanted to go put the relay node back together and test it.

After gathering up those parts, I check the Domoticz log and it's still reading temp. While it IS working, the temps are displaying wrong in Domoticz. My sensor is sending F, but domoticz thinks it's C and it converts.

I'm mentioning this because, when I open the serial monitor to confirm the node was sending F values, it of course resets the node. This killed the gateway. I got the following in my domoticz log:
2016-02-19 15:00:30.362 (MySensorsSerial) Temp (Temp)

I ran sudo cat /dev/ttyMySensorsGateway and get 'No such file' message. I interpret this to mean the gateway has stopped running, right?

Next I manually started the gateway again. It immediately starts reading the temp sensor again. After the next 30 second timer expires, Domoticz picks it right back up too.

I think I figured something out... If I restart a node with the gateway running, it kills the gateway and my above symptoms start. I'm able to repeat this without failure.

I'm going to do some more testing, but it seems that when the node sends the s=255 message, the gateway is dieing.
I want to see what happens if I turn on another node while the first is alraedy running. Perhaps I have to have all my nodes on before I start the gateway?

I am very encouraged as I at least finally feel like I'm moving forward. Was getting frustrated for awhile there.
Thanks again for the write to help me get started.

[hayduke]

Did some more testing. Now I know why it seemed related to the relay node.
The relay node needs the gateway to be listening when it wakes up. If it fails when it presents, ie the gateway is down, it doesn't try again.

I did have the relay sketch working at some point, so I don't think it's that sketch. I'm thinking I have a problem with the gateway. I work as a developer, so I've been trying to acquaint myself with the code. I mostly use SQL and VB.net in my day job. I loved C++ in college, but it's been almost that long since I used it.

Does anyone have any ideas what might be causing this? I'm going to go reread the section on the mysensors protocol and see I can spot anything wrong in those presentation messages.

[Justinian]

Hi there
I did everything according to the instructions. Installing went without complications. However, when trying to verify the gateway problems arise.

After typing

sudo /usr/local/sbin/PiGatewaySerial

I receive the message: command not found.
Also, no /dev/ttyMySensorsGateway file has been created.

When I am entering

sudo /etc/init.d/PiGatewaySerial start

nothing happens. I only get a new command line.

I can start the gateway, however, when I am entering

sudo ./PiGatewaySerial

in the Raspberry folder.

I already tried to uninstall and re-install everything, without success. Has anybody any suggestions how to solve this issue?

[mfalkvidd]

@Justinian looks like you forgot to run "sudo make install" after "make all"

[hayduke]

@mfalkvidd said:

I took a little break from this project, but I worked on it again this weekend. I decided to start from scratch and rebuild the gateway completely. I put a fresh Domoticz image onto the SD card, updated and upgraded, cloned, compiled, and installed the RF24 and Raspberry code.

Now I have the exact same symptom as Justinian

Since this used to work for me at some point, next I will try using an older Dmoticz image. I read somewhere that people had better success by NOT using apt-get update. Perhaps it's a problem with Jessie vs Wheezy? Domoticz switched kernels during on of the version upgrades.

Winter is over, so I can live without getting my furnace controls working right now. I know relays have an issue, but now I'm just needing to monitor the temperature in an egg incubator.

I'm surprised that using a rpi with this radio module directly attached is not a more popular platform. Is it just not a reliable platform? With the rpi3 out now, there shouldn't be a CPU load issue trying to act as an HA controller even with a large installation. I've got lots of ideas I want to implement if I can ever get a stable backend.

[Justinian]

@mfalkvidd thanks for your help. Unfortunately, this didn't resolve the issue. I repeated the installation, this time deliberately executing sudo make install, but the problem remained.
@hayduke Maybe this indeed is an issue with Raspbian Jessie as I am on Jessie.

[martinhjelmare]

Jessie uses a different init system than Wheezy. Systemd should be able to handle most old init scripts, but this case might be an exception.

Has anyone successfully installed this on Jessie?

A unit file for systemd would be a good addition, in any case, in my opinion.

I'm on the latest Jessie version. Prior to that I also used DietPi as a platform for Domoticz and Mysensors. I have not done an apt-get update or apt-upgrade since the install (I used the Jessie image from the Raspberry Org site).

As for load, here is the image of Domoticz CPU load of the last year:

As you can see, combining the Gateway function with the Controller function on the Raspberry 2 gives virtually no load. I could probably add the Plex Media Player software to this and still have room for some more cron jobs.

Hi - I saw enquires months ago about getting RF69 working - has anyone done so? thanks!

[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.

[micah]

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!

@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.

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.

@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.

@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.
