Error using Home Assistant with a serial gateway

[martinhjelmare]

@BastienVH

Basically all pure sensors are supported. Not all actuator types, though.

You can look at the source code for specifics. I want to add more documentation, but it's not done currently.

Your log seems to concern a motion sensor, but you said DHT?

You need to post the sensor sketch and all of the log from gateway started confirmation, to give me more background.

[BastienVH]

@martinhjelmare
Yeah, I was also trying to get my motion sketch working, so that log message may have been something left over from that.

This is everything in my terminal

I hope you can find something there...

@BastienVH

I don't see a line in the log for presentation of the child sensor, or sketch name, or sketch version, but there already seem to be info loaded, sketch name and version and value type, looking at the line before the stack trace.

Is persistence disabled? Do you present the sensor in the sketch? Can you link to or post your sketch?

I think the problem might be that you're reusing an old node id with a different sensor type that's already been loaded via persistence.

I don't think I support these dynamics at the moment. I'll have to look more closely in the code, but if you can link your sketch, that will help me confirm this.

Solution would be to clear the persistence file.

@martinhjelmare

Sorry, I was away from the computer for a little while.
I did reuse an old node id, that could have been the problem.
Assigned a new node ID and this is where I stand now:

Firts up: the node sketch:

I don't get errors anymore, but nothing shows up in the web interface.
I think the messages aren't being interpreted?

I don't get errors anymore, but nothing shows up in the web interface.
I think the messages aren't being interpreted?

You have to reboot your individual sensors so HA can see their Presentation message. Your output seems to be good for the gateway itself, but the gateway is not an actual "item" in HA, when it detects the sensors though, you should see their status.

It seems I did in fact forget to reboot my node when trying to include it in HA. (long day messing around with code...)
Here is a console log from today in which I start up HA and reboot my node.
HA receives the messages, but the node never shows up in the web interface:

Your thoughts?

[martinhjelmare]

@BastienVH

I can't see anything wrong in the log. You present properly and end by sending a value per sensor. The only thing is, there's no adding of the entity device in the log. Home assistant should report that in the log, when that happens: "adding new devices...".

INFO:mysensors.mysensors:n:0 c:0 t:3 s:9 p:read: 20-20-0 s=255,c=3,t=15,pt=2,l=2,sg=0:0

This is a presentation message for node 20 of type 17: S_ARDUINO_NODE.

First line is an internal message from node 20 to controller as request of type 6: I_CONFIG.
The second line is an internal message from controller to node as response of type 6: I_CONFIG, payload:M for metric.

INFO:mysensors.mysensors:n:0 c:0 t:3 s:9 p:read: 20-20-0 s=0,c=0,t=7,pt=0,l=0,sg=0:

This is a presentation message for sensor 0 of type 7: S_HUM.

Then you have presentation messages for sensor 1 of type 6 and for sensor 2 of type 1.
See the API to figure those out:
https://www.mysensors.org/download/serial_api_15

The last three messages are reporting sensor values:

INFO:mysensors.mysensors:n:0 c:0 t:3 s:9 p:read: 20-20-0 s=1,c=1,t=0,pt=7,l=5,sg=0:22.0

This is a set message for sensor 1 of type 0: V_TEMP, payload: 22.0.

The other two are set messages for sensor 0 of type 1 and sensor 2 of type 16.

Maybe you can try everything again. Did you disable persistence? I think it's good to have it disabled, until you know everything is working, then you can activate persistence and do the presentation a final time. Remember to delete the persistence file if you have an old one, first though.

Edit:
There's a bug in home assistant version 0.11.1, which makes it impossible to load devices on the fly. A workaround is to enable persistence, present the sensors and send a value per sensor and then restart home assistant. After the restart the sensors should show up in the gui.

[martinhjelmare]

@BastienVH

We've been troubleshooting this in the other thread, and there seems to be a problem in the code somewhere. See this post for a workaround:

http://forum.mysensors.org/topic/2831/home-assistant-v-0-11-1-with-switch-support/45

Edit:
The bug is found, and there will be a fix.

@martinhjelmare
Thanks for the heads up!
After following the steps there, I get my node up and running.
Thanks for the help!
