Converting a sketch from 1.5.x to 2.0.x

[rollercontainer]

Maybe related to this problem?
https://github.com/mysensors/MySensors/issues/449

My gateway does the same. No presentation, but sending data.

[hugows]

The API looks very clean and simple, I look forward to use it more.
Does Arduino/MySensors uses C++ features (namespaces?) to prevent name collision? In typical C projects I've seen the functions all beginning with some prefix (mysensors_).

[chrlyra]

@rollercontainer Where should the "if (presentation).." be? At the setup()?

[Yveaux]

@chrlyra there is no such thing as if(presentation)...
The presentation function implementation can be anywhere in your sketch.

[chrlyra]

@Yveaux rollercontainer pointed to this issue: https://github.com/mysensors/MySensors/issues/449, where hek asked him to add two lines of code, the first one being "if (presentation)".

[Yveaux]

@chrlyra That's what happens if you deviate from the topic... Anyway, thanks for the hint!

[Rolo6442u]

Great work ! This version looks a lot cleaner and the support for the RFM69 is more integrated. Thanks for that. One thing I'm missing and that's the specification of the encryption key for the RFM69. This was done in version 1.5.x by a user defined 16 bytes string. Now i see only a #define MY_RFM69_ENABLE_ENCRYPTION.
How and where is the key specified ? How does this make my setup unique ?

Thanks.

[scalz]

@Rolo6442u
If I remember well, it is handled by SecurityPersonalizer.ino It is sketch for signing options, and i think you can set/generate your rf aes key there. It store it in eeprom. Then you upload the new sketch with encryption define enabled. For me it's ok, as i use signing which needs to use the personalizer.
I think this works like this, not sure as i have not enabled encryption yet. Am I right @Anticimex ?

[Anticimex]

@Rolo6442u
@scalz is correct. Details are in the doxygen documentation for usage. Link is on the GitHub readme. Look under the signing module there.

[Rolo6442u]

@Anticimex
@scalz
Thanks, I got it working. By setting it to "soft" this sketch writes all key's to eeprom and will not look for a hardware siging module. The RFM69 uses the EAS key for encryption. I defined my own key again in the sketch.
Nice solution !

[Anticimex]

@Rolo6442u precisely. Glad to hear that the docs are helping and thanks!

[pascalgauthier]

How can i call the process() inside a while in the loop() ?

Thanks

[nielsokker]

@pascalgauthier

I think the function "wait()" might be useful. It is like a sleep, but now it calls "process()"

I was thinking of using it with wait(0) but I was wondering if there was any way to call the process directly.

[nielsokker]

@pascalgauthier

I'm not sure. I think the developers will know.

[scalz]

@pascalgauthier why do you need to call process ? It's already done internally by the lib. Or is it for inside some longtime loop? you still can use process but now it's _process()
Wait is not the same as sleep.
Wait : wait for a time and call _process
sleep: does not call _process. it sleeps. for a time if set

[pascalgauthier]

@scalz
Because i have while() that increment motion detected in a 30sec timeframe. And i would like to be sure that i'm not missing any cmd from the gateway. Do i need to define any additional library to use the _process() ?

[AWI]

@pascalgauthier I would recommend making your while loop non-blocking i.s.o. hacking into a MySensors function.

[scalz]

@pascalgauthier
yes it's better non blocking. for non blocking it's better to use "if" like. for beginning, I advise you to look at "blink without delay" concept. then learning a bit how a state machine works etc...could be useful to you. but it's a bit more advanced, or not..

[pascalgauthier]

@scalz @AWI

Thanks for your help !

[moskovskiy82]

Little bit confused. reading through the release notes...

Deprecated variables: V_DIMMER (use V_PERCENTAGE), V_HEATER (use V_HVAC_FLOW_STATE), V_LIGHT (use V_STATUS)

Now back to the API page for 2.0...

S_DIMMER	4	Dimmable device of some kind	V_STATUS (on/off), V_DIMMER (dimmer level 0-100), V_WATT

WHICH ONE TRUST?!

[moskovskiy82]

And if my loop statement consists only of

void loop() 
{ gw.process(); }

Rewrite like
void loop() { }

or exclude loop completely?

[Yveaux]

@moskovskiy82 said:

Rewrite like
void loop() { }

That's correct

[Maurizio Collu]

Dear all, I'm a bit lost.
I upgraded the library in Arduino to 2.0.0 and now I am having big problems.

I downloaded the sketch for the relay from the MySensors website:
https://www.mysensors.org/build/relay
but I suppose this is still for 1.5

I tried to modify the sketch as suggested - I do not receive any compiling error, but the skectch simply does not do anything. If I use the "monitor" in Arduino IDE, I do not see anything 0_1469262004446_RelayActuator2.ino

There must be something fundamentally wrong in my code, can anyone help?

[mfalkvidd]

@Maurizio-Collu the examples for 2.0 are included in the library. They can be opened directly fromthe Examples menu in the Arduino IDE. It is also possible to fetch the examples from github, see https://github.com/mysensors/MySensors/tree/development/examples/RelayActuator For the relay example.

[Boots33]

@Maurizio-Collu

You have a few mistakes in your sketch, Download the V2 sketch that @mfalkvidd has pointed you to and compare the two side by side. you will soon see where you have gone wrong. don't forget you will need to update your gateway to V2 as well, a version 1.5 gateway will not connect with a version 2 node.

[Maurizio Collu]

@mfalkvidd @Boots33

Thanks a lot, I knew I was missing something basic. For the newbies like me, it would be good to mention this somewhere (if you have not done so already and I missed it).

In the Home Assistant website it is mentioned that they only support 1.4 and 1.5. I'm trying with 2.0.

Thanks Again

[martinhjelmare]

@Maurizio-Collu

2.0 should work with home assistant, but all new features of 2.0 are not supported yet. WIP.

[rchamp]

I'm trying to upgrade my gateway to 2.0, but every time I go to upload, I get a 'error' not in sync.

I'm using just a standard nano w/ NRF24.

Note, my hardware profile is set properly to nano, 328p and proper com.

I restart app, and switched to my APM hardware profile and loaded my new 2.0 sensor code into my new APM node (DHT11 + motion) and was able to upload no problem.

Is there something i'm missing for the gateway?

Idon'tunderstandwhatwouldcauseittostopbeingabletocommunicate,

[hek]

Are you able to upload some other sketch to the nano?
Or has something bad happen to the FTDI chip on your nano perhaps?

[moskovskiy82]

Just for clarification. V2.0 gateway (MQTT client esp8266) - will it work with the 1.5/1.6 sensors? Or everything needs to be flashed as soon as possible?

[rchamp]

@hek it's actually a close nano with an FTDI board connected via serial inputs. I had this directly connected to my Vera, and communication with my old sensors was working just fine.

EDIT: Fixed. All in all, it was user error. I was trying to connect through FTDI adapter. I unplugged FTDI board, connected USB directly to nano clone, and upload worked fine.

Do I need to update mysensors plugin as well on Vera UI5?

@rchamp said:

No, shouldn't be necessary.

You could try, but the recommendation is to update the nodes as well.

[Maurizio Collu]

@martinhjelmare
Thanks Martin.

I uploaded the GatewaySerial to the arduino working as gateway, but if I upload the sketch and I open the monitor, I obtain this error:

What does it mean?

@martinhjelmare
Plus, when starting home assistant, I get this error

[martinhjelmare]

@Maurizio-Collu

Regarding the error in home assistant, that's a bug, due to specifying mysensors version other than 1.4 or 1.5. Use 1.5 and you should be fine. The bug is fixed in the dev branch of pymysensors and will be fixed in home assistant when real mysensors 2.0 support is merged. WIP.

Please post home assistant topics in the home assistant category under controllers. This is off topic in this thread.

What does it mean?

@tekka knows this best, and he wrote a post explaining some of those messages here:
https://forum.mysensors.org/topic/4347/can-t-get-sensors-talking/3

[Maurizio Collu]

@martinhjelmare Thanks a ot.
Is there any guide/manual where all these messages are explained?

Plus, is there anywhere written what all these terms mean?

TSP:MSG:SEND 255-255-0-0 s=255,c=3,t=3,pt=0,l=0,sg=0,ft=0,st=ok:

Kind Regards

[mfalkvidd]

@Maurizio-Collu do you mean except the link martinhjelmare provided?

[Maurizio Collu]

@mfalkvidd Yes, basically this part (I'm sure it is explained somewhere, but I can't find where)

255-255-0-0 s=255,c=3,t=3,pt=0,l=0,sg=0,ft=0,st=ok:

SOrry for my newbieness...

[tekka]

@Maurizio-Collu Yes, the doc is in preparation, the meaning of these messages is described here (this is a PR that harmonizes the log message and will be pushed to 2.0.1).

In brief:

TSP:MSG:SEND 255-255-0-0 s=255,c=3,t=3,pt=0,l=0,sg=0,ft=0,st=ok:

TSP:MSG:SEND refers to message sending function in the transport state machine

255-255-0-0 is the routing information, i.e. sender-last-next-destination

s=255,c=3,t=3,pt=0,l=0,sg=0,ft=0,st=ok:

• s=sensor ID (255 = internal)
• c=command (3 = C_INTERNAL)
• t=type (3 = I_ID_REQUEST)
• pt=payload type (0 = P_STRING)
• l=message length (0)
• sg=signature flag (0 = not signed)
• ft=failed transmission counter (0 = no failed uplink transmission at this* oint)
• st=send status (OK)
• : actual message (empty)

=> Your node has no assigned ID (=255) and is requesting a new ID from the controller.

Please refer to the serial protocol or API for additional information.

Good luck!

Hi,
I was trying to implement the irrigation controller but realized that was not migrated to MySensors 2.0.
I followed the instructions provided in the first post and arrived to a version that compiles with no errors. Nonetheless, as I am newbie, I would appreciate if someone could review some changes that I am not sure about. Those changes are related with the original sketch which has direct calls to process() in several while statements. First I tried to change the process() with _process() but several errors appeared, so finally I removed all the calls to process() but am not sure. I have the modified code here IrrigationController.ino in which I commented the lines added / deleted / modified. Any help / direction would be greatly appreciated.

[Boots33]

@pndgt0

The sketches that require external libraries are not included in the V2 install anymore but they are available here in the new V2 format. You will find the irrigation sketch there.

[pndgt0]

@Boots33 Great! Thank you for the quick response and the URL. I took that version. Just wanted to let you know that to successfully compile it was needed to remove the #include <LiquidCrystal.h> and probably an update to that sketch would be needed at Github respository.
Thank you again!

[Boots33]

@pndgt0 That may be because you do not have the LiquidCrystal library installed. They have the external libraries there as well

I built a 2.0 MQTT gateway and am experimenting with a sensor using 1.5 library. I can see incoming data in the serial monitor, but the data is a bit different then when I was using the 1.5 MQTT gateway. In openhab I used this:

{mqtt="<[mysensor:MyMQTT/3/2/1/V_TRIPPED:state:CLOSED:1],<[mysensor:MyMQTT/3/2/1/V_TRIPPED:state:OPEN:0]"}

But now I must skip the V_Tripped part to make it work like this:

{mqtt="<[mysensor:mygateway1-out/3/2/1/0/16:state:OPEN:1],<[mysensor:mygateway1-out/3/2/1/0/16:state:CLOSED:0]"}

Is this how it is supposed to be or do I have to make the sensor node 2.0 compatible first? I thought the payload is saved in the V_TRIPPED variable, but it doesn´t seem to work in the new 2.0 library. Pls advise-

edit:

Ok, digged a bit deeper: if I understand it right, I don´t need "V_TRIPPED" or any other value in my controllers code (which is openhab actually) anymore but still in my sensor node code of course. So the gateway will transform "V_Tripped" into sub-typ "16". Correct? So all I´ll have to change is my openhab code, right?

[Yveaux]

@siod correct. The conversion of value code to text has been removed in the 2.0.0 implementation, so now the raw values codes are reported in the topic.
