@Luc3as it seems that you have found a bug in Home Assistant. Haven't seen a Stack trace in a while. I think it would help the developers if you can post the log file including the stack trace.

@Luc3as

This is due to the node not being presented before any sensors are presented. That radio message was probably dropped.

A fix for the error has been merged at pymysensors already, buy you still need to make sure the node is presented before sensors can be added.

The node presentation message is sent automatically when gw.begin or similar in dev branch is called.

You can resend the presentation with the present method. To present the node use child id 255 and sensor type 17 for regular node or 18 for repeater node.

See
https://github.com/theolind/pymysensors/pull/38

and for discussion
https://github.com/theolind/pymysensors/pull/37

The fix will be included in the next release of home assistant.

Hi, I also struggle with the presentation of my sensors.

I've installed HA 0.18.2 over pip. My config on a raspberry pi looks as follows:

...
sensor:
  platform: mysensors

mysensors:
  gateways:
    - device: '/dev/ttyUSB0'
      persistence_file: '/home/pi/.homeassistant/mysensors.json'
      baud_rate: 115200
  debug: true
  persistence: true
  version: '1.5'
  optimistic: false

On HA startup I get:

INFO:mysensors.mysensors:Trying to connect to /dev/ttyUSB0
INFO:homeassistant.components.http:Starting web interface at http://0.0.0.0:8123

I've set up a node with the orginal Binary-Sensor example from https://home-assistant.io/components/binary_sensor.mysensors/.
If I power the node up, I get in the log:

and if I push the button on the node I get:

INFO:mysensors.mysensors:n:0 c:0 t:3 s:9 p:read: 0-0-0 s=1,c=1,t=16,pt=2,l=2,sg=0:1

INFO:homeassistant.components.mysensors:No sketch_name: node 0
INFO:homeassistant.components.mysensors:No sketch_name: node 0

So for me it looks like everything is working, but the sensor dont show up on the web interface.

What am I missing?

Hi!

First you should remove:

sensor:
  platform: mysensors

Then your node has id 0, which is usually reserved for the gateway. So that is kinda strange. It shouldn't matter for the pymysensors API, though, I think. It seems as if the sketch name is not picked up by pymysensors/home-assistant for node 0 even though that message is received.

Only dev branch is able to have sensors on gateway, and you're running version 1.5.4, and you said you connected a separate node with binary sensor.

If you don't specify a node id in the begin method in the sketch and the node hasn't got a stored old node id in the eeprom, pymysensors will provide a node id, automatically. But the lowest automatic node id should be 1. So is it possible that you have a stored node id of 0 in the eeprom of your arduino node?

You can try clearing the eeprom with the clear eeprom config sketch in the mysensors library.

@martinhjelmare

Wow thank you so much.

I've cleared the eeprom and now it gets node id 1. After removing the persistence file the sensor now shows on the web interface.
