Thanks to Pepijn i have a setup that is working, the only thing is that i receive an error, and node-red stops...

My readout when i start node-red:

There is one thing that seems faulty i think: the line "17 Jan 13:38:36 - [error] [nefit-easy-config:e4e7ec4a.1b181] Nefit initialization : XMPP authentication failure"

it also seems that two instances are started:

The config with the nefit-easy-config:bd2a3479.8b63d starts ok.

The error i receive is

[pepijn]

The XMPP errors occur when your Easy details (serial, access key, password) are incorrect. Maybe multiple easy configs are created

[jakkes72]

i found how to remove it. Seems a bit hidden....

[mvveelen]

I decided to install nodejs and the easy-server on a RPi I have running with Kodi. I finally got it working that way, but there are 2 things I don't understand:

- When I close my Macbook, the receiving of data on the Synology (where I have Domoticz running) stops. Strange, because it should query the Rpi without my Macbook, right?
- I have 6 devices, but I see in one of the screenshot in this topic that there should also be a "Nefit | Aanvoertemperatuur" ?

I'm using the latest Domoticz with Nefit Easy support (hardware). Anyone?

Edit:

I just installed nodejs and the easy-server on my Synology and that seems to work now too. Let's hope it doesn't stop receiving data when I close my Macbook.....

Oh, the steps I took:

- Make a folder where you want the stuff to be installed. I chose /volume1/Easy and gave it 777 permissions.
- cd ../volume1/Easy
- wget https://nodejs.org/dist/v5.3.0/node-v5. ... v7l.tar.gz
- tar -xvf node-v5.3.0-linux-armv7l.tar.gz
- cp -R * /usr/local/
- export PATH=/volume1/Easy/node-v5.3.0-linux-armv7l/bin:$PATH
- node -v

Result:
v5.3.0

- cd bin
- npm i nefit-easy-http-server -g
- easy-server --serial=myserial --password=mypassword --access-key=myaccesskey --host=192.168.0.124 --port=3001
HTTP server listening on http://192.168.0.124:3001

I used another port to be sure, but you can leave that behind and then it will use port 3000 by default. The IP address can be 127.0.0.1 when Domoticz is running on the same device as the easy-server, but I chose to use the IP address.

Going to close the Macbook for a while to see if it keeps working.

The easy server and experimental easy hardware does not display the same information as the Node RED version

You also need to run the easy-server in the background. That's why it's closing when you close your ssh session

Fair enough, but how do I run it in the background....?

[geezerrr]

Hi Pepijn, I've followed the Nefit easy topic for some time now but i didn't have time to finish the installation. But my compliments because it's working very good!! Thanx a lot!
Do you think it's possible to get more data from the easy into domoticz? Like gas usage, outside temp ect. ( I have an external temp sensor).

Maybe something for the future ?

Anyhow thnx for the hard work!

[pepijn]

Yes I know, the outside temp is already there does it work with the external sensor? I will try to add gas usage but I need to find out how it's stored. Other suggestions on what to add are welcome.

[geezerrr]

The "openhaardfunctie" would be nice as well.

Yes I have an external sensor.

[pepijn]

The "openhaardfunctie" would be nice as well

Do you want to set this function? You can read already, you just need to modify your flow the nefit status node show 'fp active' and 'fireplace mode'

[mvveelen]

The "Aanvoer temperature" (without the need of Node-RED) would be nice.

For me the question remains: how can I run the server in the background on the Synology / RPi .... ?

nohup ./server &

[mvveelen]

Tried that:

nohup easy-server --serial=234324 --password=password --access-key=74YnEhHHewdSaT9ae --host=192.168.0.124 --port=3001 &

But as soon as I close the Terminal window, the receiving of data stops.....

[marten]

I followed the start post of this topic to install nodejs and the files from github
to test i entered
node example/current-status.js
the text bellow is what i get, anybody a suggestion what's wrong?

[pepijn]

You did not enter your serial, accesskey and password correctly. Also please note that the Nefit easy files mentioned in the first post are outdated. You need to use Nefit-easy-cli as a replacement

[marten]

still won't work

installed nefit-easy-cli
then:
export NEFIT_SERIAL_NUMBER= "xxx xxx xxx"
export NEFIT_ACCESS_KEY="xxxx xxxx xxxx xxxx"
export NEFIT_PASSWORD= "xxxxx"

also tried the serial number and acces code without the spaces

[pepijn]

You could try adding them as command line parameters. You must enter them without spaces Please provide the error

[pepijn]

Could you just try the easy commandline utility like 'easy status'
