You were right, there was a character problem when copy/pasting the command to the terminal.
Now I can build MySensor with username and password and it works fine.

Thanks for the help!

I found a solution for my problem. In configuration.yaml I changed:

version: '2.3.2'

to

version: '2.3'

Now the errors don't show up anymore and my node is working

I actually have the same problem and do not know where it is coming from.
I tried several time to delete mysensors.json file and restart AH to try to troubleshoot it without success.

This is the errors I get exactly:

2020-02-25 19:07:32 ERROR (MainThread) [homeassistant.components.mysensors.device] Error updating Grow monitor 30 3

I checked the file mentioned in the last line here: https://github.com/home-assistant/home-assistant/blob/dev/homeassistant/components/mysensors/sensor.py
I see that V_LEVEL doesn't have a S_MOISTURE corresponding it to (line 32).
Could the error comes from the unit of measurement is not mentioned for S_MOISTURE type of sensors?

You were right, there was a character problem when copy/pasting the command to the terminal.
Now I can build MySensor with username and password and it works fine.

I made some more tests and I think it doesn't work because when I setup Mosquitto, I created a user/password but didn't do it when building MySensor gateway.

I looked at the list of options from this page and added the next 2 configuration options:

--my-mqtt-user=pi
--my-mqtt-password=raspberry

(pi / raspberry being the same user / password I set my Mosquitto user during the installation)

But when I configure the MySensor gateway I see this in the console:

[WARNING] Unknown option detected:--my-mqtt-user=pi, ignored
[WARNING] Unknown option detected:--my-mqtt-password=raspberry, ignored

Is there any other way I could try to build the gateway with user/password than this? Or is this a bug? Those 2 options are clearly written in the configuration options page for the Raspberry Pi gateway.

Hello,

I am struggling to make the initial setup of MySensors with Hassbian. I am running both on same Raspberry Pi 3.

I installed MySensor gateway on the RPi with following configuration

./configure --my-transport=rf24 --my-rf24-ce-pin=18 --my-rf24-cs-pin=24 --my-gateway=mqtt --my-controller-ip-address=127.0.0.1 --my-mqtt-publish-topic-prefix=mygateway1-out --my-mqtt-subscribe-topic-prefix=mygateway1-in --my-mqtt-client-id=mygateway1

In Hassbian I installed Mosquitto and this is how my configuration.yaml file look like:

# MQTT gateway
mqtt:
  broker: 127.0.0.1
  client_id: mygateway1
  username: pi
  password: raspberry

# MySensor
mysensors:
  gateways:
    - device: mqtt
      persistence_file: '/home/homeassistant/.homeassistant/mysensors.json'
      topic_in_prefix: 'mygateway1-out'
      topic_out_prefix: 'mygateway1-in'
  optimistic: false
  persistence: true
  retain: true
  version: '2.3.1'


# Debug logger
logger:
  default: info
  logs:
    homeassistant.components.mysensors: debug
    mysensors: debug

I followed the instructions from Home Assistant page and made a dummy sensor node with following code:

// Enable debug prints to serial monitor
#define MY_DEBUG

// Enable and select radio type attached
#define MY_RADIO_RF24

// Enable repeater functionality for this node
#define MY_REPEATER_FEATURE

#include <MySensors.h>

#define CHILD_ID 1
#define MY_NODE_ID 1

bool initialValueSent = false;
bool state = false;

MyMessage msg(CHILD_ID, V_LIGHT);

void setup() { }

void presentation()  {
  sendSketchInfo("Relay+button", "1.0");
  present(CHILD_ID, S_LIGHT);
}

void loop()
{
  // Need to send initial values for Home Assistant
  if (!initialValueSent) {
    Serial.println("Sending initial value");
    send(msg.set(state));

    Serial.println("Requesting initial value from controller");
    request(CHILD_ID, V_LIGHT);
    wait(2000, C_SET, V_LIGHT);
  }
  
}

void receive(const MyMessage &message) {
  if (message.isAck()) {
     Serial.println("This is an ack from gateway");
  }

  if (message.type == V_LIGHT) {
    // We got initial values from Home Assistant
    if (!initialValueSent) {
      Serial.println("Receiving initial value from controller");
      initialValueSent = true;
    }
    
    // Write some debug info
    Serial.print("Incoming change for sensor:");
    Serial.print(message.sensor);
    Serial.print(", New status: ");
    Serial.println(message.getBool());
  }
}

I make sure that I send the sensor S_TYPE in the presentation and that I also send an initial value out.

The Arduino console output is the following:

I tried using MySensor log parser and if I understand correctly the node does not get answer from the gateway.

On the Raspberry Pi, I checked the logs from Home Assistant and they seem fine.

2019-09-12 07:39:12 DEBUG (SyncWorker_17) [mysensors.persistence] Loading sensors from persistence file /home/homeassistant/.homeassistant/mysensors.json

So then I stopped MySensor gateway service and run it myself using the command

cd MySensors
sudo ./bin/msgw

This is what I have as output

I would assume the problem comes from the gateway that do not stay connected and constantly reconnect but I am out of clues of what I am doing wrong.

Any idea is appreciated, thanks!
