Converting a sketch from 1.5.x to 2.0.x

[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?

@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?

No, shouldn't be necessary.

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

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:

0;255;3;0;9;Starting gateway (RNNGA-, 2.0.0)
0;255;3;0;9;TSM:INIT
0;255;3;0;9;!TSM:RADIO:FAIL
0;255;3;0;9;!TSM:FAILURE

What does it mean?

Plus, when starting home assistant, I get this error

@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.

@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.

@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.
