Requirements

• Fibaro HC2
• Heat pump with Luxtronik II Heating & Heat pump control with firmware lower than 3.81
• Web server (PHP enabled)

Luxtronik II

Luxtronik II is a heating and heat pump control which can be found in various heat pump systems:

• CTA (Switzerland)
• alpha innotec
• Novelan
• Wolf

Mine has firmware version 1.76 which runs a Java Web interface.

 

Make sure to configure a fixed IP address or reserve an IP address for it on your Router/DHCP server and you are able to access it (use Internet Explorer because of Java issues with Chrome).

Web server

The Web server is required as interface between the Java Web interface of Luxtronik and the Fibaro system. Make sure to use a fixed IP address for your Web Server!

Create a sub folder on your Web server in the web directory and name it heating. On my Linux server the path is: /var/www/html/heating

Download the file fibaro.php and change the IP address and eventually the port (try 8888 if 8889 is not working) in the configuration part of the file:

Open the file in your Web Browser to check if data of your heat pump is gathered: http://IPADDRESS/heating/fibaro.php

Fibaro Virtual Device

Configure the virtual device

Download the Virtual Device and add it to your Fibaro HC2: Download

Change the IP address in the configuration to the IP address and port of your Web Server:

Use the virtual device

In the overview of the device you are able to see the current status:

The following control options are currently implemented:

Control your Boiler

Auto: Normal mode

Party: Heats up boiler to 50°, then sets mode automatically to Auto

Aus: Turn off

Control your Heating

Auto: Normal mode

Party: Always on

Aus: Turn off

Temp set back: Adjust your temperature by +0.5° and -0.5°

Thank you

I found a lot of information on the following web sites:

The washing machine is in the cellar and laundry will be forgotten inside… At least one reason for me to create a scene which sends a push notification when the washing machine runs and when it’s finished.

 

The only thing you need, is a Z-Wave plug which can handle power peaks of your appliance. I use a Plug from Fibaro:

How can we detect a running or finished state? As seen on the picture below a wash cycle has some peaks and troughs which fall down to neraly zero. Therfore a scene must ignore those ups and downs. This can be achieved by using the last modification value on a device.

 

Using a loop which requests power usage data from the plug every 20 seconds resulted in using a global variable for the current state of the washing machine.

• Off: currently not used (maybe for future use)
• On: When plug is turned on, but Washing machine not running
• Running: When a wash cycle is running

 

The scene:

--[[
%% autostart
%% properties
50 power
%% globals
Waschmaschine
--]]

PlugID = 50;   -- Plug ID
Phone1 = 525;  -- ID Phone 1
Phone2 = 445;  -- ID Phone 2


-- Only allow one instance of the current scene to run at a time
if (fibaro:countScenes() > 1) then
  fibaro:abort()
  fibaro:debug('Scene runs already. Killing...');
end


local Wallplug =  (tonumber(fibaro:getValue(PlugID, "value")) > 0 ); -- Ist Wallplug an
if (Wallplug) 
    then 
      while true do

fibaro:debug('Start LUA...');
local tempDeviceState0, deviceLastModification0 = fibaro:get(PlugID, "power");
fibaro:debug('Last modification: ' .. deviceLastModification0);

fibaro:debug('Waschmaschine Check ob fertig...');
if (( tonumber(fibaro:getValue(PlugID, "power")) < 10 ) and (os.time() - deviceLastModification0) >= 300) then
  	if 
 		( fibaro:getGlobalValue("Waschmaschine") == "Running" )
	then
                fibaro:debug('Waschmaschine läuft noch...');
    	fibaro:debug('Waschmaschine is ON');
        fibaro:call(Phone1, "sendPush", "Waschmaschine ist fertig"); -- Push Handy
        fibaro:call(Phone2, "sendPush", "Waschmaschine ist fertig"); -- Push Handy
		fibaro:setGlobal("Waschmaschine", "On");
	end
end

fibaro:debug('Waschmaschine Check ob läuft...');
if 
 		( fibaro:getGlobalValue("Waschmaschine") ~= "Running" )
	then
	    	fibaro:debug('Variable ist nicht gleich RUNNING');
if (( tonumber(fibaro:getValue(PlugID, "power")) > 10 ) and (os.time() - deviceLastModification0) >= 60) then
	    	fibaro:debug('Waschmaschine is RUNNING');
            fibaro:call(Phone1, "sendPush", "Waschmaschine läuft"); -- Push Handy
            fibaro:call(Phone2, "sendPush", "Waschmaschine läuft"); -- Push Handy
            fibaro:setGlobal("Waschmaschine", "Running");
end
      end
    fibaro:sleep(20000);
      end
   end

 

After two years of using flat icons for my rooms in my Fibaro HC2, I decided to try a different look. After searching for some nice icons, I found some round icons on http://www.flaticon.com/.

 

Go to http://www.flaticon.com/ and search for “car” for example:

 

Choose PNG and select as size 128:

Upload the icon in your Home Center 2 as room icon:
