node-red-contrib-mysensors release thread

[magpern]

@tbowmo I feel a little confused on how to use this node-red plugin. Is this something like "a node-red plug-in framework", but you have to invent the wheel yourself kind of solution?

I have just opted for the Home assistant (hass.io) system as the hub for my home automation.
Home assistant, according to documentation, is mysensors enabled, but compared to other add-ons, like zigbee2mqtt, zwave2mqtt, the mysensors implementaton is like a child's tricycle, while the others are sports cars.
The zigbee2mqtt, you just turn on and off the IKEA light buld six times and it is added, whereas the mysensors you have to type configuration files and have limited graphical administration possibilities.

So I thought, what if the mysensors could talk to mqtt and get into home assistant that way (my gateway is serial).

I understand the node-red implementation enables you to decode the messages as you like, but do I really need to invent how it should decode it and send it to mqtt?

Are there any ready to use implementations of the plug.in?

Could it support "auto discovery"? So you just have to turn the device on, and voila, it appears in home assistant (if mqtt auto discovery is turned on)?

[tbowmo]

@magpern this module is more if you want to only use nodered for your home automation, without Hass.io or the likes.

Most of the standard controllers (domoticz, openhab, home assistant etc) are all able to handle the mysensors network directly (more or less), and handle the device registration for you.

My module for nodered is implementing a crude controller, that only handles out node id's to the mysensors network, when asked for, and then leaves everything else up to your imagination, for how to wire things together behind the scenes.

That being said, if you only need to convert your serial mysensors gateway into mqtt, I do have a small python script that I use for that particular case, as my nodered instance can't access the serial Ports from my docker swarm setup. So this script is running besides everything else. I can post it tomorrow if interested, as my pc is closed for the night now.

I'd love to try the script! /Magnus

@magpern

It's more or less the script below, I removed some stuff from my utility meter, that I also handles in my script (but isn't needed for just mysensors).

#!/usr/bin/python3

import serial
import paho.mqtt.client as mqtt
import time

mysensors = serial.serial_for_url('/dev/ttyNRF24', 115200, rtscts=0, timeout=1000)
mysensors.isOpen()
mqtt_connect = False

def mqtt_reception(client, userdata, msg):
    payload = msg.payload.decode("ascii")
    topic = msg.topic.split('/')
    topic.remove('mys-out')
    mymsg = ';'.join(topic) + ';' + payload + '\n'
    print("out <- ", mymsg)
    mysensors.write(str.encode(mymsg))

def mqtt_connect(client, userdata, flags, rc):
    print('Connected')
    mqtt_connect = True
    client.subscribe('mys-out/#')

def mqtt_disconnect(client, userdata, rc):
    print(rc)
    
client = mqtt.Client('mys')
client.on_connect = mqtt_connect
client.on_message = mqtt_reception
client.on_disconnect = mqtt_disconnect

client.connect('192.168.1.64')

def handle_data(data):
    print("in -> ", data)
    s = data.split(';')
    payload = s[-1]
    s.remove(payload)
    topic = 'mys-in/' + '/'.join(s)
    if mqtt_connect: 
        client.publish(topic, payload.rstrip())

if __name__ == "__main__":
    client.loop_start()
    mys_data_str = '';
    util_data_str = '';
    while (True):
        if (mysensors.inWaiting()>0):
            char = mysensors.read(1).decode('ascii')
            mys_data_str += char
            if (char == '\n'):
                handle_data(mys_data_str)
                mys_data_str = ''
        time.sleep(0.01)

Is there still possibility to install it please ?
Thanks a lot

NPM is trying to build sqlite, because it cannot find a suitable pre-built one for your architecture, it fails because you do not have the needed tools installed for this on your machine.

Might help if you install build-essentials (sudo apt-get install build-essentials, assuming you are on a debian like install)

I currently use it on node-red 1.1.2, without problems. But I'm using plain node-red in a docker container..

[DenisJ]

@tbowmo said in node-red-contrib-mysensors release thread:

ed 1.1.2, without problem

Thanks for the answer.
I have now Node-Red 1.3.3 under Home Assistant installed.
But I must search on net how can I install the build-essentials from the docker console.

Do you know if is there some other node that I can install from the palette that maybe incluse the build-essentials please ?

Thanks again
Denis

[tbowmo]

What I did way back when I got it up and running in docker, was to jump into the container shell, and install the package manually (So you are using the same node.js version that node-red is using).

You could also (in that docker shell) do a apt install (given that it builds upon a debian based image).

something in the line of:

$ docker exec -it <id of container running node-red> /bin/bash
# now you are in docker..
$ apt install build-essentials
$ cd <to your node-red data directory>
$ npm install node-red-contrib-mysensors
$ exit

Above is taken purely from what I think is the right commands, as I have not tried working with home-assistant for a while.

[DenisJ]

@tbowmo said in node-red-contrib-mysensors release thread:

apt install build-essentials

I think I have not the apt inside of Node_red docker.

Can I install it from outside in this case.
Sorry but I'm very beginner so I need some basic info in this case.

Thanks a lot again
Denis

[electrik]

In Home Assistant you have the Node Red configuration (under supervisor). There you can add packages to be installed under system_packages: []

[DenisJ]

@electrik said in node-red-contrib-mysensors release thread:

system_packages
I have try to insert in the system_packages like this:

But it give me errore when start:

I think I'll make some translate node by my self
Thanks a lot again

Denis

[electrik]

Shouldn't it be

build-essentials

?

[DenisJ]

@electrik said in node-red-contrib-mysensors release thread:

build-essentials

I try it but it give me same errore.

I think that that package must be here in this link like the error log tell
Do you have Home Assistant installed ? if yes... do you have this "essentials" installed also ?
Thanks again
Denis

[electrik]

Yes I have home assistant but don't have the build essentials. I did some more reading and it seems like a package of build tools. Perhaps @tbowmo knows which specific one is needed?

[DenisJ]

No problem @electrik I have already set the Node-Red to translate my node sensor in human leggibile data :-)

And now I can see it like this:

All ok and thanks a lot for the help
Denis

[tbowmo]

@electrik

When I said that you needed the package "build-essentials" I assumed that you where running on a barebone ubuntu distribution, and not in docker. This complicates things, but it seems that others do have the same issue with node-red and sqlite on home-assistant forum.

One solution is given here: https://community.home-assistant.io/t/how-to-get-access-to-sqlite-on-hassio/241439/3

As said earlier I do not know anything about the internals in home-assistant and their specific docker / node-red setup.
