Nefit Easy Smart Themostat for HR-Boilers

This thermostat is also known as:

*Nefit Easy (Netherlands) [https://www.welkombijnefit.nl/nl/easy]
*Junkers Control CT100 (Belgium)
*Buderus Logamatic TC100 (Belgium)
*E.L.M. Touch (France)
*Worcester Wave (UK)
*Bosch Control CT‑100 (Other)

The thermostat sends data to a central server at Bosch.

With the nefit-easy-server software it is possible to query the Bosch server for data.

Detailed info about nefit-easy-server on [https://github.com/robertklep/nefit-easy-http-server Link].

Serial-Number, Access-Key can be found on the back of the Thermostat (you have to lift it off the wall) or in the app under menu Info - Productinfo.

If you forgot your password, you can reset the thermostat. For the nefit-easy-server the password may not contain the character !, # (and perhaps other special characters).

Also the Nefit Easy Serial number (aaa aaa aaa) and the acces key (aaaa aaaa aaaa aaaa) have to be filled in without spaces like (aaaaaaaa and aaaaaaaaaaaaaaaa)..

=='''Installation'''==

#Install nefit-easy server
#Go to menu Setup - Hardware and select type Nefit Easy HTTP server over Lan interface
##Enter a Name (eg Nefit Easy)
##Enter remote address (eg 127.0.0.1 when nefit-easy server is installed on the same system as Domoticz)
##Enter a port (always 3000, this could conflict with Grafana) <br />

===Install nefit-easy-server===
Short summary of steps necessary to get the nefit-easy-server installed:

*Update node.js to 10.x version (or other version that suits your needs, check here for a list: https://nodejs.org/en/download/releases/

<code>curl -sL https://deb.nodesource.com/setup_10.x | sudo -E bash -</code>

<code>sudo apt-get install nodejs</code>

*If necessary / not installed automatically, also install npm

<code>sudo apt-get install npm</code>

*Install pm2 to control the service

<code>sudo npm install pm2 -g</code>

<code>sudo pm2 startup systemd –u pi --hp /home/pi</code>

*Install easy server

<code>sudo npm i nefit-easy-http-server -g</code>

*Create start script

<code>touch nefiteasyhttpserver.sh</code>

Use your standard edit. For example:

<code>vi nefiteasyhttpserver.sh</code>

*Add lines:

#!/bin/bash
/usr/bin/easy-server --serial=your-serial --access-key=your-access --password=your-password --host=127.0.0.1 >/dev/null

*Save your file.

<code>chmod 755 nefiteasyhttpserver.sh</code>

''Note:''

For the nefit-easy-server the password may not contain the character !, # (and perhaps other special characters).

Also the Nefit Easy Serial number (aaa aaa aaa) and the acces key (aaaa aaaa aaaa aaaa) have to be filled in without spaces like (aaaaaaaa and aaaaaaaaaaaaaaaa).

*Start script

<code>pm2 start /home/pi/nefiteasyhttpserver.sh</code>

<code>pm2 save</code>

*Check script ....

<code>pm2 list</code>

<code>pm2 show nefiteasyhttpserver</code>

*Change SSL settings (when you use recent Linux distributions)

[Source https://github.com/robertklep/nefit-easy-http-server]

<code>vi /etc/ssl/openssl.cnf</code>

change the following keys to these values:

<code>MinProtocol = None
CipherString = DEFAUL</code>T
{| |[[File:NefitEasy.jpg]]|

|}

===Troubleshoot===

* Devices not updating

When the Nefit devices are not updating in Domoticz and/or Error: Nefit Easy: Error getting http data! is shown in the log:
check if the nefit easy http server process is running. In a terminal session run:

<code>curl <nowiki>http://127.0.0.1:3000/api/status</nowiki></code>

It should give a json result.

Error when starting pm2 nefiteasyhttpserver.sh: the ownership of directory '''home/<user>/.pm2''' has to be changed.

Linux command:

<code>sudo chown <user> -R .pm2</code>

After this command:

<code>pm2 start /home/<user>/nefiteasyhttpserver.sh
\</code>

<code>pm2 save</code>

Then restart the system and NefitEasy server is running.
<br />

===Fireplace mode===

FireplaceMode switch (Dutch: openhaard functie) on a linux pc:

1. Install the nefit-easy-cli (https://github.com/robertklep/nefit-easy-cli) as the standard plugin has no function for this.

2. Make 2 bash scripts in /home/<user>/domoticz/scripts for on/off switching:

<nowiki>''</nowiki>fireplacemode-on.sh<nowiki>''</nowiki><syntaxhighlight lang="bash">
#!/bin/bash
easy --serial=SERIAL --access-key=KEY --password=PASSWORD put /ecus/rrc/userprogram/fireplacefunction '{"value":"on"}'
</syntaxhighlight><nowiki>''</nowiki>fireplacemode-off.sh<nowiki>''</nowiki><syntaxhighlight lang="bash">
#!/bin/bash
easy --serial=SERIAL --access-key=KEY --password=PASSWORD put /ecus/rrc/userprogram/fireplacefunction '{"value":"off"}'
</syntaxhighlight>3. Make the 2 executable with <code>sudo chmod +x yourfilename.sh</code>

[[Dummy for virtual Switches|Add a virtual dummy switch]] in Domoticz named for example "Nefit Fireplacemode"

[[Managing Devices#Edit Device|Edit the switch]] an add the 2 scripts as on and off action eg <code>script:///home/<user>/domoticz/scripts/fireplacemode-on.sh</code>

Now you can switch the FireplaceMode from Domoticz and also use it in scripts.
