Hello, good evening!!
I'm trying to build two Nodes with two Arduino Pro Minis (a Gateway and a Node, to be precise) connected to each other using the Pjon Protocol.
If I understand correctly, the nodes are connected to each other by a single wire, specifically Pin 12 by default.
I just can't create the sketch.
Can someone provide the Gateway and Node scripts?
Thanks for your help.

Good evening!! I also fought with some of those modules believing they didn't work, in the end the problem was the power supply !! Get tested now they work.
Here is the scheme I used:

Everything is about providing GOOD Power

I apologize for the bad English

I for my Atmega328 (Arduino pro Mini) at 16 Mhz I am using 0xFF 0xDA 0xFD

I'm interested, can you share some more info on this feature ??

@skywatch said in Go to loop(); when parent/gateway can't be found.:

ai tempo, potresti dare un

Just insert this line:

#define MY_TRANSPORT_WAIT_READY_MS 1000

before : #include <MySensors.h>

this is all, so if the Gateway is not available after 1000 Milli seconds, the scketch is performed anyway

@niclas said in 986/5000 first steps with battery node:

le defi

currently the node absorbs 19mA, it seems a bit high !!
As a motion sensor I am using an sr501, without removing the voltage converter on board !!
If you can give me some more info on Minicore and how to disable the analog converter ??

As the title suggests, I am starting to take the first steps to develop some battery-powered nodes, and I started with some work already done found here on the forum.
I have some Atmel 328P barebones on which following this:
link text
procedure and with an arduino Uno and Arduino IDE, I managed to burn an 8Mhz Bootloader with internal oscillator, and to load a simple scketch of a motion sensor, which should work on battery power, and during sleep, it has an absorption of 0 , 19mA (maybe a little high ???).

At this point reading this discussion: link text

it reads that I should set the fuses in order to disable the BOD, which if I understand correctly serves to make my circuit work even with lower voltages !!
Someone tells me the precise setting that I have to give, so I modify my fuses with AVRDUDESS ???

Then another thing, when I connect the serial monitor through my arduino Uno that I use to load the sketches I get this Why ???

@mfalkvidd ok now I understand, and then commands an Arduino or other. thank you

@berkseo thanks for the scheme. but therefore don't use a sensor ?? i'm sorry noni and clear how do you detect the presence of water ...

@berkseo I'm sorry if I can, but what kind of sensor are you using to detect water ?? I would like to do something like that but with an Arduino pro !!

@skywatch said in Motion sensor increase Time high status via software:

Hello and sorry, if I gave the idea of being courteous !! sorry again
I didn't publish the code because I really don't know where to start, but now that I understand WAIT, that in MySensors and a separate thing, I also understand your example, and I thank you for helping me !!
But then again I didn't know that this WAIT, was something different from DELAY
I answer little, because I'm a little busy these days ..... But anyway for now thanks again for help

@skywatch
WAIT and DELAY, aren't they the same thing ??
You can explain me better, because I didn't know this difference, thanks in advance for your availability

Searching, I found this

We know Millis, it's already been used several times, but what I can't solve is the code, I can't process the code !!

I had thought of WAIT or rather DELAY, but the sketch is more complex than just the motion sensor, and using DELAY is not correct because it would block the execution of the code.
But can't I find other solutions ???

Hello!!
I would need a little help, if possible !! I'm building a Movement node with the PIR sensor HC-SR501, and I started from the example already present on the MySensors site.
With this sensor there is a potentiometer that allows you to adjust once passed in the HIGH state, how long it must last before returning LOW.
What I want to do is put the potentiometer at 0 and do this work in the Code
So every time there is a movement must communicate the new state to the gateway, stay a time of 10 seconds ON and then if the status is New LOW communicate the new state or at each movement lengthen those 10 seconds

I don't know how to create the code, does anyone have any examples or can you help me ??

Hi, no one knows how to help me

Hello!! As mentioned, I'm slowly introducing OTA into my nodes.
But I found a strange problem, after having done OTA of a scketch, it's all OK and the node works.
But after 3/4 lack of power supply to the node (for example, lack of electricity, due to bad weather), the node no longer has the scketch inside and to make it work I have to make a new OTA.
A behavior, can anyone help me ???

I write my scene here

• Arduino pro Mini 5v 16Mhz
• Radio nRF24
• For OTA I used MYSController
• FUSE Arduino settings L = 0xF7 H = 0xDA E = 06

Thanks in advance of the Attention

Good morning!! I need a clarification, I have some MySensors nodes that work regularly, and on some of these I have also activated the Firma Software, so far all Ok.
Now, as a matter of convenience, I am introducing the OTA overruns.
My question is, in a node with a signature to which I want to add OTA, how to proceed ???

1. I customize the Node
2. Load the new Bootloader
3. Load the new sketck via OTA

it's correct?? or are the steps to follow others?

Thanks to those who want to clarify my ideas

Hi, I'm bothering you for an info.
You said that: "request a value at a node"
And one thing that interests me, can you share how you do ?? Thanks for the time you want to dedicate ....

Hello!! And thank you again ......
A really good job, it's something that was definitely missing ......
I would suggest to the directors to expand the guide on OTA you better explain the steps to change channels and make a link to your great job !!

Now if I understand this and the Bootloader that I have to load on my Arduino Pro-Mini, in practice insert in the path of the IDE of Arduino when I make the updates use that channel

As soon as I can I try them and I'll let you know, in a lot of thanks again ......

@sindrome73 Hi Good evening, and I'm sorry for the delay in the reply.
As you have never done a Bootloader, if you are kind enough to do it, I thank you.
The channel I'm using is the "Channel 84" for now I'm using only the 16MHZ Bootloade, but if you want, the others are fine too.
In addition you can give me some starting point to be able to fill in too ??
Thanks for your availability, greetings

@guillermo-schimmel Thanks for the reply.
Very useful, but can you tell me more accurately what software to use to recompile after making the change ????
Maybe some links to the software to download ..... thanks again for the availability

@mfalkvidd Hello.
From what I read it is possible to somehow modify the channel for OTA updates, this is also said here.
https://www.mysensors.org/about/fota

But I can not find other info on how to proceed to change the channel .....
Can you give me some other clarification or link to follow ???

this is a good place to start and start to understand.
I'm not a lot of diggers, however I start reading something, and in case I'll ask for help
In a lot of thanks

@kimot I did not understand what you tell me, can you explain better or with some examples ??

Hello
So if I understand, a node from domoticz can only ask the status of a sensor connected already him, and not the status of other nodes of the network!
So it is impossible for me to create nodes / displays to display the status of other sensors in the network.
The only way is to use some old mobile phone as a display point

do you mean that it is not possible to request those data from the node that will make the display ??

@pjr
yes, I intend to receive data from devices that do not belong to that node, but to other nodes.
So random devices of the network

Hello!!
I would like to make some small displays to put in the house where you can see the status of some lights and temperatures.
So it was my intention to retrieve this info from Domoticz from time to time. If I understand correctly I should use the "request" command only that I have no idea where to start ....
Has anyone already done something like this and wants to share their experience and / or a piece of code already done ??

you could also provide the links on eBay of the pieces

@fac13 I looked a little bit the problem is not MYSbootloader, because if I have seen well, it has a configuration files where you go to Change the channel !!
The problem is the .HEX files that you go to put in the IDE of Arduiono and that write the new BootLoader on Arduino, these predispose the channel 76 in reception, and here the problem .....
In addition, as already mentioned, I noticed that the arduino of which you change the Bootloader have problems when you remove the power and put it back .... Many times they lose the sketch

Excuse me but I go a little OT ..... What dashboard and this are you using?

No for OTA the Defaul channel and 76, the one with which and by default MYSENSORS, you should change it to MYSController, but I do not know how to do it !!
I also sent a message to the TEKKA user who invented MYSController, but I did not get an answer !!
If someone knows how to do it ?? It would give us a great help ....

@sindrome73 Hello!! after many tests maybe I could solve the problem, but now I have another question.
So I discovered that the problem that OTAQs did not work is because I changed the default Radio channel of mysensors for RF24 radios

Now my question and this, you can use a different channel for OTA updates, if you like ??

Hello!!
I managed with some time doing OTA updates of a node using MYSBootloader, and after some tests, OTAs work.

The node in question is a 5v pro-mini arduino with RF24 radio

But I'm having problems now, I noticed that the node, followed by some power failures and as if he lost the sketc, and then I have to reload the sketch via FTDI.

In addition now on this node, once the sketch is reloaded I am no longer able to do the OTA update via MYSController connected to a serial gateway.

In addition I wanted to ask for a clarification, for an Arduino Pro-Mini 5v at 16Mhz, the fuses with AVRDUDESS must be set as follows:

L = 0xFF
H = 0xDA
E = 0x06

This could be for you: https://it.aliexpress.com/item/plastic-outer-shield-for-thermo-hygro-sensor-spare-part-for-weather-station-Transmitter-thermo-hygro-sensor/32793243933.html?spm=a2g0s.8937460.0.0.f3dWg7

Ok, now it's clearer

@kalina
And then once connected to the Raspy ?? What are you doing?? And a new thing for me !!

@kalina said in What did you build today (Pictures) ?:

ione di installare questa scatola

if I can know !! The audio socket what is it for ???

Other sketches work, already tried !! And this from problems with 2.2

Hello!! Sorry if I'm late.....
So I tried to do the checks as suggested .....

If I load the schetck with Mysensors Ver 2.1 the Arduino IDE gives me 28620 Bytes used 93% of the space

If I load the schetck with Mysensors Ver 2.2 the IDE of Arduino gives me 29310 Bytes used 95% of the space

So it could be a problem of space and therefore makes my Arduino Pro unstable .....
Tomorrow I'll try to load the same Scketch on An Arduino Uno that should have a little more space ..... I keep you updated on the developments

Ok tomorrow calmly I will make these changes and update you .... A Tomorrow, and thanks for now .....

But it is the same with both 2.2 and 2.1.
With Arduino Pro Mini, enabling the signature debugging must be disabled because it exceeds counque the maximum available memory .......

Ok .... Tomorrow I'll do it ..... But it will be difficult to have the Gateway Log because with the signature enabled, the sketch is very large, and does not allow me to activate the Debug ....

Yes indeed I have already said this !! So true that to have the DEBUG of the signature I had to disable the DEBUG.

But with this same script, and going to Mysensors 2.1 it works !!

Here is the log with the Debug signed abbreviation.
I specify that I had to disable // # define MY_DEBUG because the scketch is too big

tell me how to abbilitate the detailed signature debug .....

Here I am at home .... I proceeded to redo the procedure and this sot is the log ....

I had to put an image because the last signs that mida I can not copy them as text ....

In the evening ..... Now I'm at work and I can not

I apologize, but I did not understand what you tell me ....

I would like to add that the script without the signature with the 2.2 version works, while the signature works only with MySensors 2.1

@anticimex

532/5000
I made the customization from the beginning, with MySensors 2.2.0

I followed these steps:

• The EEPROM has been deleted
• Open SecurityPersonalize.ino inserted the new Key
• loaded the scketch and it does not go

I redid the same procedure above, then EEprom deleted, SecurityPersonalize file, and loaded the scketch, but this time using Mysensors 2.1.1
And here it worked ..... The same thing I did on Several Pro Mini at 5V 16Mhz and the result is the same ..... That's why I assume there may be something wrong with 2.2.0

Good morning, for one of my Weather Station (very early stage) I used the code below. Which works perfectly with MySensors 2.1.1
Yesterday I updated my Arduino IDE to Version 2.2.0 and when I try to compile the code it goes, but once loaded the scketch on my arduino Pro, it does not work, while reloading the code compiled with MySensors 2.1.1 It works !!

I think there is something wrong with the latest version of Mysensors

I wanted a clarification !! As already mentioned in another of my posts, I'm implementing the signature in my network, I wanted to ask, the procedure I find here described

https://www.mysensors.org/apidocs-beta/group__MySigninggrpPub.html

and the same whether I use MySensors 2.1.1 and MySensors 2.2.0 ???

Or should I use different procedures ??? Thanks 10000

I had thought of an alternative because however the signature requires much more memory of the script, and much more substantial communications !! That's why I wanted to somehow use nodes with signature and nodes without signature !!
But from what I understood, the only node to have a secure network and to have all the nodes with the signature in the network .....

Thanks anyway for the idea of a double network ......

I believe that the use of two gateways, and therefore 2 networks, is perhaps the most correct solution !! A secure network with a signature and a slightly leaner network with all the other Sensors .....
And a right solution !!

Further information !!
Using #define MY_SIGNING_REQUEST_SIGNATURES only in the nodes and not in the Gateway, could it be a way to introduce the signature only between some nodes ???
Without incurring a degradation of security ??
It's correct?? Or is it a wrong thing ????

Good morning!! I wanted to ask some information, I'm starting to build some nodes, made up of Arduino Pro Mini 5v and as radio NRF24L01, and I'm starting to insert a bit of security !! Since I have noticed that without the network and very exposed, in fact it is enough another system that is the same close that commands everything in practice.
So I proceeded, at least to change the default radio channel and introduce the Soft Signature.
Now I would like to know, the signature I have to introduce by force for all nodes, or I can use it only for those nodes that I consider most sensitive (such as lights, gate) and leave without the nodes, which for example send only temperature values, and then I think of minor importance ?????

This entering the code: "#define MY_SIGNING_WEAK_SECURITY"

However, since I read: https://www.mysensors.org/apidocs-beta/group__SigningSettingGrpPub.html#gaf44407e0f498eca7069adf5e59ffe052

Doing this involves a significant weakening of the protection !!

So how do you use nodes with Firma and nodes without Signature ??

I hope I managed to explain my doubts well .... Thanks to those who can help me .....

But then if I understand correctly, with the current stable version 2.2.0 you can also use:
  #define MY_SIGNING_SIMPLE_PASSWD "mysecretpw"

And it is no longer necessary to customize the nodes and the Gateway ??

If it is so!! Is it safer or less secure ???

@anticimex said in Help Signing:

Hi,
first of all, you have spelled a define wrong,

#define MY_SIGNING_REQUEST_SIGNATURE

should be

#define MY_SIGNING_REQUEST_SIGNATURES

Secondly, you have to enable signing on the gateway as well.
Thirdly, you have to personalize your devices (as per the documentation) or signing won't work at all.

Hello!!
I resume my discussion !! Finally after a long time, I was able to understand the "3" point that Anticimex told me. Where it is said that the device (node ​​/ gateway) must be customized through the SecureActuator.ino files.

I did this way:

I loaded the scketch SecureActuator.ino, on the node or on the gateway, and I followed these steps, and we're talking about using only the Firma Software.

Enable GENERATE_KEYS_SOFT
This will generate random keys for HMAC (signing) and AES (encryption). Copy the keys generated and replace the corresponding definitions under "User defined key data", specifically MY_HMAC_KEY and MY_AES_KEY.
Disable GENERATE_KEYS_SOFT and enable PERSONALIZE_SOFT
This will store the HMAC key and the AES key to EEPROM. It will also write a checksum of the personalization data in EEPROM to be able to detect if the data is altered.
Personalization is now complete.

At this point if I understand correctly I write my scketch, adding at the beginning before Config.h
How much:

#define MY_SIGNING_SOFT
#define MY_SIGNING_REQUEST_SIGNATURES
#define MY_SIGNING_SOFT_RANDOMSEED_PIN 7

And load everything, on the node ...... It should be all right now ?? Quite right???

Of course, loading this scketck, gate from the Sardinian SecureActuator.ino, but this is normal because however the HMAC (signing) and AES (encryption), are stored in the EEPROM of arduino !! Quite right???

At this point I'm using the Signature correctly or do I have to do anything else ???

Cabbage!!

Good evening!!
Question definitely stupid, but I would like to understand how to use MYSController, I downloaded the program, launch the files .exe, but then what should I do to connect to the nodes or else ???
My Mystery Network and so composed:

• Domoticz that runs on Raspberry with MQTT
• MQTT Gateway with NRF24L01 radio
• 2 Nodes communicating with the Gateway with radio NRF24L01

How do you use MYSController in these cases ???

Thanks 1000 for the help

We hope that in some way the user is given the chance to decide whether to combine the nodes

If this is the case, I started from node ID 99 and arrived up to Node 67, doing tests ....

However, the behavior in this sense is strange, and I think it is certainly a Domoticz problem.
Or at least the Domoticz Development Team should give the possibility to manage how to use the sensors, whether to combine or not

In practice it happens that with a node composed of DTH and BMP180, it creates 4 sensors, as follows:

• Only one Temp
• One Temp / HUM / Pressure
• Two for the pressure .....

The data reach up to Domoticz, surely, I see them updated in the HARDWARE tab, but then they do not update ..... or happen that some are updated and others are not of the 4 created.

The problem is that when multiple sensors are generated, the node sends the data, but does not update in domoticz

Hi Goodmorning.

I had already read this discussion, but still does not indicate a precise solution from what I understand.
In the end, somehow I managed to show Domoticz the DHT22 and BMP180 sensors. In a united way, but able to update, because most of the time creates different sensors between Teperatura Pressure and then even if the data arrive from the node, they are not updated.
Surely all this is a problem of Domoticz, which should try to solve !!

Let's see if others can help us .....

Hi, I'm trying to assemble a mini Weather station, consisting of a temperature and humidity sensor (DHT22) and a BMP180 pressure sensor.
But Domoticz, in addition to the problem of combining sensors, after a while no longer reads the values sent by the Node.
Is there a way to vitar that domoticz combines sensors ??? I also tried to look, but it seems like a Domoticz problem

Sorry the question, but this mysensos.json files where it is located ?? I did not understand it !!

Ah.... Ok

for a sketch piece where the ASC711 is used. because I would like to use it for a similar project, but I do not know how to use it to have a reading for AC. so since you used an asc711 in your project, I thought you could help me ....
Thanks 10000

Hi, if you have a minute of memories of me ???

thanks .... I wait because I do not know how to use it

would it be possible to have the ACS711 sketch ???

Discovered the problem !! I fed through the "RAW" pin while feeding through the VCC

Ok is now working

No firm !! What does not work and Arduino Pro Mini at 3V.
Do not start with two 1.5V batteries.
To work it requires at least 3.3V

How do I do it to make it work with two 3v batteries?

Hello!!
I tried to build a first battery sensor with an Arduino Pro Mini 3V but feeding it with 2 1.5V batteries the sensor will not work !!
But do I need to use a Step Up Boost Module or do I just follow the directions on this page ???

link text

Another sore point !! I do not know how to edit Myconfig.H
Send me some links where I can see?

I copied the same code in the gateway.
For the gateway however I have to disable the debug otherwise sketch and too big !!

So I loaded this code both in the Relay Node and in the Gateway:

#define MY_SIGNING_SOFT
#define MY_SIGNING_REQUEST_SIGNATURES
#define MY_SIGNING_SOFT_RANDOMSEED_PIN 7

In the Knot Debug I see this:

317050 TSF:MSG:READ,0-0-3,s=1,c=3,t=16,pt=0,l=0,sg=1:
317072 TSF:MSG:SEND,3-3-0-0,s=255,c=3,t=17,pt=6,l=25,sg=1,ft=0,st=OK:FADEB1BB0B066C3F08094CC8C74FD0A63EC503598F2B14C14B
317150 TSF:MSG:READ,0-0-3,s=1,c=1,t=2,pt=0,l=1,sg=1:1
317231 TSF:MSG:ACK REQ
317234 TSF:MSG:SEND,3-3-0-0,s=1,c=1,t=2,pt=0,l=1,sg=0,ft=0,st=OK:1
Incoming change for sensor:1, New status: 1

I think something is working !! Now I would like to try to mix in the network a node that does not require signing

But is it so difficult to load an example of a gateway + node that requires signature + a node that does not require signature?

It would help many in my situation !! I try to study the whole thing again but the signature for those like me, is at the beginning of the weapon is not easy as explained

They used them but they brought me to the same page anyway

https://ci.mysensors.org/job/Verifiers/job/MySensors/job/master/Doxygen_HTML//group__MySigninggrp.html#personalization

https://www.mysensors.org/about/signing

https://ci.mysensors.org/job/Verifiers/job/MySensors/job/master/Doxygen_HTML//SecureActuator_8ino-example.html

But I only find examples for nodes !! While for Gateway I find nothing !!!

It's been a month since I read and read the documentation and the various examples, but I can not understand it well !!
And very difficult for me .....

I understand that documentation is important but an example of Gateway sketch would be much faster

For Signing on Gateway I have to enter the same Code ???

While point 3 does not make me clear !! What should I do in my Relay Node?
Or is it something I then have to do in all the nodes ??

I have a MQTT gateway, which interfaces with Domoticz.
I want to make a node relay, and I want to add a Soft signature.
Then add the following code to the Sketch before Config.h:

#define MY_SIGNING_SOFT
#define MY_SIGNING_REQUEST_SIGNATURE
#define MY_SIGNING_SOFT_RANDOMSEED_PIN 7

It's right??
In the Debug I see no difference, and normal ??
Thanks to who can help me ....

Hello!! For convenience, I wanted to pair 2 MQTT Gateways, with different IP addresses, and only one MQTT Broker installed on a Raspberry, where Domoticz also turns.
The two Gateways work on different channels with the NRF24L01 modules, but by connecting them, the modules sometimes work in Times no !!
Do you have any suggestions for pater use 2 Gateway

As I said, my English is not good and therefore it is difficult for me to follow the discussions.

That's why I was asking for a snapshot already done, in order to study the code and understand how to solve ....
  If anyone can help me ????

Hello!! I'm also trying to implement SOFT Signature, but because of my poor English I have many problems !!
Someone could post the socket of a node + a working MQTT gateway.

So you can study the code and understand how it works !!!

Thanks 1000 in advance to who can help me

I got it!! So if I use domoticz as a controller, I should retrieve data from domoticz ...... Okay ???

No, I do not want to communicate with other mysensors nodes, but I also support another receiver with NRF24L01, and send data from nodes !!

For example, I want to make my gateway load the temperature data on a web page, and this data is taken from a node my sensors

Hello!!
I'm slowly beginning to learn mysensors .....
For now I am just an amateur.

I would like to know if I can somehow, once a node (such as a temperature node) has been created, this in addition to communicating with the gateway, I can somehow take advantage of the radio module to send communications to another arduin. Using this radio module or adding another .......
It's possible???

I do not understand. Tell me I'm available

Grazie mille!!

Thanks!!
