Nefit Easy™

[pepijn]

NEW VERSION v1.1.0 of the Node is available

Code: Select all

sudo npm -g update  node-red-contrib-nefit-easy

• Changed: the communication, only a single connection will be made and reused by all nodes.
• Implemented: Timeout setting to the Easy configuration node
• Changed: Flow-temperature output
• Some bugfixes

I found an error in setting the temperature. New version 1.1.1 available

Pepijn,

How would you advice me to update Robert's library? Now I only have the following, which is incomplete and outdated

pi@raspberrypi ~ $ sudo npm -g list | grep nefit
├─┬ [email protected]

Should I first remove the old nefit-easy-client install, and then separately install in separate directories, the core, commands and cli libraries?

Thanks for you advice

would be good to know the way forward. Same here. Have the client version installed, but not the new cli. Should I uninstall the old one and install the cli and then the node-red 1.1.0 version of your node-red flows/scripts?

[pepijn]

The node has its own dependencies so they are not used for the cli. If you want to use the cli (I can't imagine why) you should install it separately.

[dorenberg]

ok. Just to be clear. I will just uninstall the client (old 1st version) and delete the current node-red flow. Afterwards install your version of the node-red scripting. Enter parameters and done.

What do mean with node-red scripting? You don't need the old scripts (/opt/nefit) anymore.

[dorenberg]

I will delete those too. I meant the node-red-contrib-nefit-easy github package.

You should use npm instead of github. Just to be clear its not a script but a node, a native addition to Node-RED

Hello, i started today with domoticz, and found the nefit part...
Now i am trying to install the nefit stuff, but am facing a problem:
After i install the node-v5.3 (or 5.4) i receive this:

pi@raspberrypi ~ $ node -v
Segmentation fault
pi@raspberrypi ~ $

My image is the domoticz-raspberrypi-sdcard-3530...

Did you install the correct node binaries? Pi1 or Pi2? ARMv6 or ARMv7?

[pepijn]

Just to be complete, the node is (automatically) published on nodered.org http://flows.nodered.org/node/node-red- ... nefit-easy

[jakkes72]

Did you install the correct node binaries? Pi1 or Pi2? ARMv6 or ARMv7?

as far i know i have a Pi2,but will look closer when i am at home.

I followed these steps:
1 sudo ps -ef | grep node
2 sudo /etc/init.d/nodered stop
3 node -v
(VERSIE 0.10.4 OID ZOU ER MOETEN STAAN)
4 wget https://nodejs.org/dist/v5.3.0/node-v5. ... v7l.tar.gz
5 tar -xvf node-v5.3.0-linux-armv7l.tar.gz
6 cd node-v5.3.0-linux-armv7l
7 sudo cp -R * /usr/local/
8 node -v
(VERSIE 5.3.0 ZOU ER MOETEN STAAN)

I am able to copy the files to /usr/local/ But the command node -v gives a segmentation fault.


edit:
Found it: I thought i had a Pi2, but i have a Pi1 B+
the command node -v gives the right output

[jakkes72]

I managed to get it running:

pi@raspberrypi ~/node_modules/nefit-easy-commands/example $ node status.js
Temperature is set to 17.0°C, current is 18.3°C.
Outside temperature is 6.0°C.
System pressure is 1.4 bar.

But how do i get this data in Domoticz/Dashboard?

Hi,
I promised to give some results:
From the outside everything looks fine and is working like it should which is great. When taking a look at the log I found a few errors; really a few: 12 to be exact in over 30 hours runtime. I found: INVALID_RESPONSE: 8x; REQUEST_TIMEOUT: 3x and 1 other error with the log text '[error] [nefit-easy:f5e93b14.0a16c8] Error: error:0606508A:digital envelope routines:EVP_DecryptFinal_ex:data not multiple of block length' where [nefit-easy:f5e93b14.0a16c8] is 'nefit-update'.
From another thread I learned that the timeout is harmless, for the other errors I don't know. But it doesn't seem to bother much since everything functions like it should. So thanks again for a great job.

PS. I made a little lua script that updates the setpoint widget once per hour with the same value to prevent that the widget turns red. It would be a nice feature if that could be built into the node. So pass the setpoint on change but at least once per hour. If its possible...

What is the version of the node you are using?
Most of the problems mentioned above should already be solved

Code: Select all

sudo npm -g list | grep nefit

The latest, 1.1.1

I made a little script in php to get these data in domoticz.
If you can handle that I can send you the script.
Otherwise you can use node-red:

hi kc27,

Maybe you can post the script on the forum

[kc27]

This is the php-script, I use for importing nefit-easy values:

Code: Select all

<?php

    $jsondata = shell_exec("easy -V --serial=xxxxxx --access-key=xxxxxx --password=xxxxx status");
    $data= json_decode($jsondata);
    var_dump($data);
    $data_array= get_object_vars($data);
    if (array_key_exists('in house temp', $data_array)){
        $temp_current = $data_array['in house temp'];
        echo 'current temp '. $temp_current."\n";
        $result = file_get_contents('http://raspberrypi:8080/json.htm?type=command&param=udevice&idx=1&nvalue=0&svalue='.$temp_current);
        echo $result."\n";
    }   
    if (array_key_exists('temp setpoint', $data_array)){
        $temp_setpoint = $data_array['temp setpoint'];
        echo 'setpoint temp '. $temp_setpoint."\n";
        $result = file_get_contents('http://raspberrypi:8080/json.htm?type=command&param=udevice&idx=2&nvalue=0&svalue='.$temp_setpoint);
        echo $result."\n";
    }

This only works when:

• node.js v4 or higer is installed
• nefit_easy_client (commandline) from Robert Klep is installed
• php5 is installed
• I have in Domoticz created
  • a dummy thermostaat (Settings/Hardware)
  • in that thermostat I created two virtual sensors with idx=1 en idx=2 for room temp and setpoint temp
• When you run this script on your raspberry and you have access to the website secured with username/password then you have to enhance your whitelist with your machinename (for instance raspberrypi) (viewtopic.php?f=6&t=9890)

This the output from the script:

Code: Select all

    object(stdClass)#1 (22) {
      ["user mode"]=>      string(5) "clock"
      ["clock program"]=>      string(4) "auto"
      ["in house status"]=>      string(2) "ok"
      ["in house temp"]=>      float(19.5)
      ["boiler indicator"]=>      string(3) "off"
      ["control"]=>      string(4) "room"
      ["temp override duration"]=>      int(0)
      ["current switchpoint"]=>      int(15)
      ["ps active"]=>      bool(false)
      ["fp active"]=>      bool(false)
      ["temp override"]=>      bool(false)   
      ["holiday mode"]=>      bool(false)
      ["boiler block"]=>      NULL
      ["boiler lock"]=>      NULL
      ["boiler maintainance"]=>      NULL
      ["temp setpoint"]=>      int(19)
      ["temp override temp setpoint"]=>      float(18.5)
      ["temp manual setpoint"]=>      int(20)
      ["hed enabled"]=>      NULL
      ["hed device at home"]=>      NULL
      ["outdoor temp"]=>      int(6)
      ["outdoor source type"]=>      string(7) "virtual"
    }
    current temp 19.5
    {
       "status" : "OK",
       "title" : "Update Device"
    }
    setpoint temp 19
    {
       "status" : "OK",
       "title" : "Update Device"
    }

When you save the script in /var/www/update.php you can test it in your browser with http://raspberrypi/update.php, or with the commandline:

Code: Select all

php /var/www/update.php

I made a cronjob for it which runs every 5 minutes:

Code: Select all

*/5 * * * * sudo php /var/www/update.php >/home/pi/update/update_out.txt 2>&1

When there are problems you see it in /home/pi/update/update_out.txt

[Holland]

Thanks, looks good. Will give it a try when I have a moment

[Holland]

Pepijn,

Kind request. Can you maybe post a new version of your flow, which includes the single connection feature. Just want to see how to get this running properly. Thanks
