Nefit Easy™

[peerke72]

Robert Klep released a new beta version.

This seems to make cpu consumption and memory consumption stable again.
It's still a beta version but it works a lot better for me.

More details can be found on: https://github.com/robertklep/nefit-eas ... -414141929

edit1: 21-8-2018, version 5.02 is now final and released, so @all please check if it solves also your problems.

edit2: 26-8-2018, i'm running the new version about week now and it's still running stable

Hi All,

Previously i had some issues with Nefit on my synology with version DSM 6.1.7-15284 Update 2 while my old DSM version 6.0.2 has no issues.

XMPP Authentication failure, so i decided to update nefit with npm update neftit-easy-http-server -g but it get's worse.

After that Nefit won't even start anymore.

Then updated NODE JS and NPM to the following versions

node -v v8.9.4
npm -v 5.6.0

but without any luck.

Then i decided to remove everything, NPM,node and nefit and rebooted the NAS.

Then i installted node js 8.9.4 and NPM 5.6.0 and installed nefit again. The installation seems fine, but nefit won't start.

-ash: ./easy-server: No such file or directory

So i went to /usr/local/bin and saw that the symbolic link was not removed during the uninstallation process. Normally this is not a problem but the link linked to something does not exist anymore.

root@DS411:/usr/local/bin# ls -l
total 12
lrwxrwxrwx 1 root root 58 Sep 14 15:25 easy-server -> ../lib/node_modules/nefit-easy-http-server/bin/easy-server

So i removed the symbolic link and created a new one.

root@DS411:/usr/local/bin# ln -s /volume1/@appstore/Node.js_v8/usr/local/bin/easy-server easy-server

and Nefit is started again!

root@DS411:/usr/local/etc/rc.d# netstat -a|grep 3000
tcp 0 0 localhost:3000 0.0.0.0:* LISTEN

Hopefully this will help other people.

Thanks @jurgen,

early June I had similar problems.
I also found the 'old' link, removed it and was able to get the easy-server running again.

However, I used to use pm2, as suggested in https://www.domoticz.com/wiki/NefitEasy

Now I don't have pm2 any more and noticed it isn't needed any more.

However, I don't understand how to create a startup script, as in, what should be written down in the easy-server.sh file.
Is what is written at the end of the wiki page https://www.domoticz.com/wiki/Synology# ... _DSM_6.0.2 the content for the script?
If so, what and where exactly should I change in this script for it to work? I have a very limited understanding of all those languages. I understand I have to put in the details of serial number, access key password, in the ENTERSERIAL, ENTERKEY and ENTERPASSWORD parts.
But do I remove all or some of the #?
Do I have to make other changes?

Hi Joeneh,

The link to wiki for synology with nefiteasy, i wrote that tutorial a while ago to put some pieces together for myself and other people who need that.
The following values needs to be edited:

NEFIT_SERIAL_NUMBER=SERIALNUMBERINVULLEN
NEFIT_ACCESS_KEY=ACCESSKEYINVULLEN
NEFIT_PASSWORD=WACHTWOORDINVULLEN

Place the script in the following directory:
/usr/local/etc/rc.d

Name it:
easy-server.sh

Edit the permissions:
chmod 755 easy-server.sh

for testing purposes you could start the script
./easy-server.sh

@jurgen,

thanks,
however, testing it gives the following:
-sh: ./easy-server.sh: /bin/sh^M: bad interpreter: No such file or directory

what's wrong?
I am running DSM 6.2.1

I think it is a copy paste issue. Copy the script from the forum to notepad and then copy the script in VI of NANO.

[JoeneH]

It is not a copy paste issue. Copying the forum text to notepad++ gives exactly the same as copying it to windows notepad and then to notepad++. I don't use VI or NANO.
I save the file in notepad++ as unix script file and then copy it to /usr/local/etc/rc.d and change the permission to 755.

I must say I have hardly a clue what the script does exactly, I have no experience writing scripts, but I noticed the following
The script has this line:
PIDFILE=/var/run/$NAME.pid but theer is no file called easy-server.pid in /var/run

And should the line
SCRIPTNAME=/usr/local/etc/rc.d/$NAME
perhaps end with $NAME.sh
Because the file is easy-server.sh and NAME=easy-server
It also has
USERNAME=root
but I never use root anywhere, I log on as admin when connecting to to the synology NAS, and I don't see $USERNAME anywhere in the script.

EDIT
Googling the error does point to a problem with DOS/Windows line endings. Using Notepad++ and saving the file as a unix script I would hope this is not the issue... Well, it was. I had to change the format of the file to Unix in the settings somewhere in Notepad++

Now, running ./easy-server.sh gives the following
Usage: /usr/local/etc/rc.d/easy-server {start|stop|restart}

Does that mean it works? Should I restart the NAS now? Or can I manually start the script and not rebooting the NAS?

Sounds like your script is executed. You don't have to reboot the NAS, just execute this command and add 'start'. But it is always good practice to reboot your NAS so you know that it starts after a reboot too.

[JoeneH]

Domoticz wasn't getting any data from the Nefit-easy, so I tried ./easy-server.sh start and it showed the following:
./easy-server.sh: line 45: /var/run/easy-server.pid: Permission denied
nohup: appending output to ‘/var/services/homes/admin/nohup.out’

Using sudo ./easy-server.sh start the message was:
nohup: appending output to ‘nohup.out’

Now Domoticz is getting data. I'll try rebooting tomorrow. EDIT: script is running automatically after reboot. Thanks.

But what is this nohup.out file all about? Seems unnecessary to me. Can I somehow stop this form being created and filled?

The nohup.out file is filling up with data about every 30 seconds
The nohup.out file contains the following:

Good news JoeneH, it seems like you have running nefit-easy.

I've got this issue also sometimes when i copy paste some scripts to unix, for me it helps to do it using notepad or notepad++.
Regarding your questions:

When you log on to your system you do it als admin but with root you have full access on your synology. I start always my scripts with root, it makes it easy so that permissions will not be an issue. (less secure, i know)

the PID file is created in var/run when the script is started, this is done so that it could not be possible to run it twice.

the nohup question, i don't know.

[JoeneH]

Today I updated Webstation to 2.1.6-0146 (which added support for php7.2 it says) and DSM 6.2.1 update 1 to DSM 6.2.1-23824 update 4 (mainly security updates), so it requested a reboot but after that the nefit process did not run and now I can't get it started again...

I am not sure whether this happened when updating Webstation or DSM. I did that in one go. I usually update packages and DSM when new updates are available.

starting the nefit-easy server manually (sudo ./easy-server.sh start) does not give any information back. Domoticz just says 'Error getting http data'.

Does someone have solutions or suggestions?

[waltervl]

Hi, new member here I am running the Nefit Easy plugin for some weeks now. No real issues here, I only get connection issues with the Nefit Easy server due to network issues I presume. But only very limited (max 1 per day).

I have a fireplace so i would like to use the fireplace mode (Openhaard) function but that is not programmed unfortunatly.
I installed it myself, I described the way I implemented it in the wiki discussion of the Nefit Easy for reference: https://www.domoticz.com/wiki/Talk:NefitEasy

[Dutchsea]

I made custom icons for the Nefit Easy. You can upload the attached zipfile via Setup => More Options => Custom Icons

I also replaced the "override.png" and the "override_mini.png" icons in home/pi/domoticz/www/images. This will change the setpoint image.
(Probably needs a cache refresh in your browser for the new icons to appear)

Hi,
I have huge spike in my nefit gas-usage graphs ... deleting the entry with shift-click does not work ...

Screen Shot 2019-04-07 at 15.20.09.png (33.28 KiB) Viewed 3714 times

Looks like some counter did roll-over or something like this.
This happens a couple of times per month, so in the end the totals and the graphs are unusable.
Is there some way to fix this ?
like (if entry > average last 24h {set entry to (average last 24h)} ?

[Dutchsea]

I have a similar incorrect Spike also on Sunday. Its just not Nefit related. Its on my zwave Fibaro plug that monitors my fridge.

Almost 2.7 Million kWh in 1 day.

To add a little color to PM2 thingy. I had myself some issues to let it autostart. (used the work perfectly)

Only if you are using Jessie (check via hostnamectl) the following workaround solves the autostart issue;

1. Delete the pm2*.sh file in /etc/init.d
2. sudo pm2 startup systemd –u pi
3. pm2 start nefiteasyhttpserver.sh
4. pm2 save

Then reboot the machine to check if it works


* credits to this guy: http://tech.scargill.net/pm2-node-red-and-the-rock/

Adding to this (already good fix); I suggest to add the following:

1. Delete the pm2*.sh file in /etc/init.d # If this file exist. I believe higher PM2 versions do not use it anymore...
2. sudo pm2 startup systemd –u pi --hp /home/pi
3. pm2 start nefiteasyhttpserver.sh
4. pm2 save

Adding `--hp /home/pi` in step 2 changes the default pm2 home path to /home/pi/ (where our .pm directory is located).
Now when pm2 loads after a reboot, pm2 will use the correct dump.pm2. This file starts the previously saved service(s)
(Which we saved using pm2 save)
This will also do the same for other saved services (such as sonos: service.js)

Without this path pm2 will use the ´empty´ dump.pm2 file in the /root/.pm2 directory. And thus the previously saved services are not started.

[Dutchsea]

Additionally to my previous post (above);
I noticed that starting the nefiteasyserver increased my cpu load from 2% to 33% as well as an increase in temperature from 50C to 65C.
After quite some checks/puzzling I noticed the the nefiteasyserver was running twice generating conflicts that resulted in the high load.
The server was running for both user root and for user pi:
