Can't add nodes to HA

[sSpeaker]

I have about 15 nodes and they works well with openhab. But I can't add them to HA.

GW and nodes are on 1.5.

Do I need to fix something in the presentation procedure? Is it possible to add nodes manually?

[martinhjelmare]

Have you checked the serial output from your node? My guess is you don't have perfect communication between node and gateway and are dropping some messages. You can also try adding a short wait between presentation messages. The missing message from your log is the presentation message of the node, which is sent in the begin method in your sketch.

It's possible to add sensors manually by editing the JSON persistence file, but it's not the recommended approach. If you have comm issues, I would try to fix those first, cause they would impact the performance of your sensors even if you would have them added in home assistant.

Please post a parallel serial log from your node and the home assistant log after start. Also make sure you set log level to debug for mysensors.mysensors and include all lines from mysensors. You should have more lines in your log than posted above.

Fixed code with gw.wait(50). There was an error on sending third child before that:

...
send: 1-1-0-0 s=3,c=0,t=1,pt=0,l=0,sg=0,st=fail:
...

Now sketch looks like that:

...

  gw.begin(NULL, NodeID, false);
  gw.wait(50);
  gw.sendSketchInfo("Light Lux Sensor", "2.1");
  gw.wait(50);
  gw.present(CHILD_ID_LIGHT, S_LIGHT_LEVEL);
  gw.wait(50);
  gw.present(CHILD_ID_HUM, S_HUM);
  gw.wait(50);
  gw.present(CHILD_ID_TEMP, S_TEMP);
  gw.wait(50);
  gw.present(CHILD_ID_MOTION, S_MOTION);
...

@sSpeaker

The node presentation message is missing from the gateway log. It should be in the beginning.

What version of home assistant are you running?

[sSpeaker]

@martinhjelmare said:

$ hass --version
0.28.2

Not really sure why there are no presentation messages on GW side. According to the log it was sent successfully.

It's possible to add sensors manually by editing the JSON persistence file.

Can you share an example of this file.

[martinhjelmare]

Here's an example of a JSON persistence file:

i have "the same" problem at Home Assistant
I have got only Serial Gateway with 2 temperature sensors (only for test). MySensors V2.0 in the Arduino IDE. I do the presentation:

0;255;3;0;9;Starting gateway (R-NGA-, 2.0.0)
0;255;3;0;14;Gateway startup complete.
0;255;3;0;11;Szafa

0;0;1;0;0;0
0;0;2;0;2;
0;1;1;0;0;0
0;1;2;0;2;

HA response:

"Node 0 is unknown."
"Requesting new presentation for node 0"
"Node 0 is unknown , will not add child 0."
"Requesting new presentation for node 0"
"Node 0 is unknown , will not add child 1."
"Requesting new presentation for node 0"

I even try send this strings by arduino Serial and SoftwareSerial ..
When HA says about Requesting serial gets "0;255;3;0;19;"

0;255;3;0;9;Starting gateway (R-NGA-, 2.0.0)  //no effect on HA log
0;255;3;0;14;Gateway startup complete. //no effect on HA log

0;0;0;0;6;  //HA: 0;255;3;0;19;
0;1;0;0;6;  //HA:  0;255;3;0;19;

I don't know, what to do... i need to connect 2 or 3 Serial Gateways with 5 sensors each GW.

There's a bug in mysensors 2.0 where the gateway doesn't present itself in all cases. See here: https://github.com/theolind/pymysensors/issues/51

Either use the workaround mentioned in the github issue, or upgrade to dev branch of mysensors, where this bug is fixed.
