coolchip / node-comfoair Goto Github PK

Hi can i use this also in home assistant?

commands.js:

• label: 'Get ventilation levles' ->levels
• rotaitions -> rotations at several places

Zehnder talks about intake, exhaust, supply and extract. Or extract, supply, incoming and outgoing.

This library uses supply, exhaust, outgoing and outside.

This is my guess how it translates:

• outside = intake / incoming
• supply = supply
• exhaust = exhaust / outgoing
• outgoing = extract

Or....

• outside = intake / incoming
• supply = supply
• exhaust = extract
• outgoing = exhaust / outgoing

Based on my current experiments on adiabatic cooling, I guess the second one is the correct one.

I leave it here for somebody who is also searching for translation between the different terms used.

Personally I'd prefer extract and intake/incoming are used, even if that is a breaking change. Now it's fizzyfuzzy

Hi all and thanks a lot for this nice node to connect the comfoair system!!

Since a while i'm getting this error while usinge it in Node Red:

"comfoair [/dev/serial/by-id/usb-Prolific_Technology_Inc._USB-Serial_Controller_D-if00-port0] runCommand(getTemperatures): Connection closed. Please open Connection first."

I have no idea why this happen and how i can fix it.
Hope someone can help me on this.

If you need something else, please let me know!

Hi Sebastian,

Long time not "spoken"! :)

I got a problem since some time, and I did not realize till today it was in this package caused by 3460ba4

node-red-contrib-comfoair gives these errors:

9 Apr 20:53:08 - [error] [comfoair:c5f08486.64a36] TypeError: SerialPort is not a constructor
9 Apr 20:53:08 - [error] [comfoair:f912a0a0.e8fe98] TypeError: SerialPort is not a constructor
9 Apr 20:53:08 - [error] [comfoair:d1308d38.3511f] TypeError: SerialPort is not a constructor

Eventually I got here: https://serialport.io/docs/guide-upgrade#upgrading-from-9x-to-10x

Everywhere this needs to change:
const SerialPort = require('serialport'); -> const { SerialPort } = require('serialport');.

• node-red-contrib-comfoair/comfoair-connection.js
• comfoair/ComfoairStream.js

        this.port = new SerialPort(options.port, {
            baudRate: options.baud || 9600
        }, cb);

has to change to

        this.port = new SerialPort({ 
            path: options.port,
            baudRate: options.baud || 9600
        }, cb);

I tested successfully with both downgrading back to serialport 9.2.8 and the above fixes with 10.5.0.

Question:

I have a ComfoAir 350 and a HA Installation with NodeRed. What do you think? Can I give this a try?

Exsys EX-6030 - Serial Server Mini, Serial Ports 1 RS232:

As I read in the manuals, I should be able to connect it with socat and therefore perhaps works with your node-comfoair Integration.

The parameters for the setVentilationLevel command are in the wrong order. (Tested on ComfoAir G90-150HL).

The correct order for this device is.

• exhaustAway
• exhaustLow
• exhaustMiddle
• supplyAway
• supplyLow
• supplyMiddle
• exhaustHigh
• supplyHigh
