💬 MySensors Library - v2.x

[hek]

We talked about splitting up this page in more use-case based pages.

[cimba007]

Nice to hear, keep the good work up!

[ileneken3]

In the "Create Repeating Nodes" section, could you please change:

#define MY_REPEATER_NODE

to

#define MY_REPEATER_FEATURE

I wasted a lot of time trying to figure out why my repeater node wasn't working.

Thanks for a great product!

@ileneken3

Thanks for reporting, updated.

what is difference between MY_PARENT_NODE_ID and MY_PARENT_NODE_IS_STATIC ?
when i add "MY PARENT NODE ID" to sketch of end node , so end node dont connect to controller directly ? and dont connect to other repeaters node? even when parent node is fail ?

edit : i test this features but dont work ! i want the my end node connect to controller with for example parent with node id 3 ! node 3 is a repeater.... but every time (with move and reset) end node choose a new parent...

Hi, I could not find a setCommand() message Api to chose between SET or REQ, is this done on purpose? I think it may be legitimate for a node to send a REQ command instead of the default SET.
Looks like mSetCommand(msg, C_SET) works but I'd avoid using not standard API calls.
Thanks!

void request(uint8_t childSensorId, uint8_t variableType, uint8_t destination);

@martinhjelmare Thanks, I've completely missed it expecting it somehow in the message constructor section, my bad! Thanks again

Hi I just finished configuring a site map having the sample node (S_DOOR) code above as the only thing and I noticed that it only updates once (only at every restart) to the Paper UI Control, The Basic UI, and to the Classic UI, I've already inserted a prinf to check if it would print to the serial monitor, and to also see if the value is changing on every loop and it is changing.

But when I looked at the Karaf Console, the send() doestn't seem to be reflecting there:

[tismoj]

Please disregard my prev inquiry, I was able to find a solution that same day, but it required me to modify MySensors library (inside RF24_spiMultiByteTransfer function) and also exposed one of the functions in RF24.h to get it to work.

[APL2017]

Please confirm that to have node configured as repeater only, it is sufficient to have the following code written:

#define MY_DEBUG
#define MY_RADIO_NRF24
#include <SPI.h>
#include <MySensors.h>
#define MY_REPEATER_FEATURE

void setup()
{
}
void presentation() {
}
void loop()
{
}

[mfalkvidd]

@apl2017 I don't think you need to include SPI.h
#define MY_REPEATER_FEATURE (and all other MySensors defines) must be placed before including MySensors.h

[APL2017]

Thank you MFalkvidd. I was wondering why many examples in your library have SPI.h library called while have no SPI communication required, it sounds like it can be removed from them as well..
Also, do I need to place CHILD MySensors defines before including MySensors.h? It is not how many examples are done, please clarify.

[mfalkvidd]

Which examples are you referring to? I am not able to find any occurrences of including SPI.h in the examples:

Micke @ Quasi Arduino/libraries/MySensors HEAD
$ grep -ir 'SPI\.h' examples/ | wc -l
0

The child ids are not used by the MySensors library. They are only used in the sketch, so there is no need to define them before including the library.

[APL2017]

@mfalkvidd I am referring to the following code example on Build page of MySensors site: Distance, Door/Window/Button, GPS Sensor, IR Sender/Receiver, Parking Sensor, Servo, Temperature, UV

[mfalkvidd]

Thanks for clarifying @apl2017
Those examples use external libraries and are therefore placed outside the main MySensors git repo. Some of the external libraries might need SPI. I doubt most of them do though, especially button and servo.

I'm not sure how to verify that in an efficient way though. We woldn't want to break the examples.

[APL2017]

@mfalkvidd One of the efficient ways to do it (if doable) is to replace site examples with links to main MySensors git repo. I noticed that some examples on site are incorporated into the pages, some are done as links already. I realize thou that examples in git repo could be different. The goal of git repo examples, as I see it, is to show technology capabilities covering majority of typical applications, while on website you may also publish some real exotic examples, such as sky stars, or whole house fan.

Please don't get me wrong, I love MySensors and very pleased with technology, documentation and support. This is just in my nature to attempt to clarify and optimize whatever I can. My colleagues at work hate me for this...

[mfalkvidd]

@apl2017 the reason those examples are separate is that they require external libraries to be installed. So replacing them would not work.

[mfalkvidd]

Maybe I should expand on that.

MySensors has two git repos:
The MySensors library (https://github.com/mysensors/MySensors ) which contains the library and all examples that do not require external dependencies.
https://github.com/mysensors/MySensorsArduinoExamples which contains examples that require external dependencies.

The MySensors library can be installed from the Library Manager in the Arduino IDE. Installing the MySensors library won't break any of your existing non-MySensors sketches, or sketches from other libraries. All examples included in the MySensors library will work without installing other libraries.

Installing MySensorsArduinoExamples (which must be done manually) can cause warnings or compile errors to your existing non-MySensors sketches. Example sketches in this repo requires the libraries included in the MySensorsArduinoExamples repo. In some cases, the libraries included in MySensorsArduinoExamples are incompatible with upstream versions of the same library, which will cause problems.

Examples from both repos, and examples from openhardware.io, are listed on https://www.mysensors.org/build
The examples that come from the git repos are linked, so the build page always displays the latest master version from github.

The pages on https://www.mysensors.org/build that require external libraries have a note about requiring external libraries, and instructions on how to install them.
