A Whirlpool/jacuzzi Fehler from Vitawell

Leider muss ich dieses post schreiben weil der Whirlpool (Jacuzzi) ich vom www.vitawell.de, eine firme im Berlin, ist wirklich problematisch geworden. Der firme meldet sich auch nicht mehr. Ich wird gern das hier nicht schrieben. Ich hoffe das verändert sich noch oder zu mindest andere Käufer sind vom die Problem informiert. Der firme ist vom Robert Lamprecht betrieben und oft (immer für mich) sein Sonn Bernard Lamprecht macht der Montage arbeit.

Eigentlich habe ich schon eine review im google geschrieben aber der Datei bilde funktionieren da nicht. hier noch mal die punkten und bilde:

Ich habe eine Außenwhirlpool (1500L) von die verkauft für deutlich über dein Baumarkt Pool Preis, so ein Preis lohnt sich nicht, meine Meinung nach. Die firme reden auch keine klar text, das ich die nicht mehr vertrauen kann. Ich habe auch der gleiche Problem das man die nicht am Telefon ran kriegst. Die haben jetzt auch meine Termin zwei mal verschoben und nicht zurück gerufen. Der Pool funktioniert an sich aber es kommt immer Probleme mit der Heizung. Immer wieder springt der Sicherung aus.

der Sicherung has noch mal raus gesprungen diese Woche (16/07/2018) - Datei folgt

Ich musste selbe eine Datanlogger dazu kaufen um zu sehen das es funktioniert nicht, es gibt keine eingebaute Meldung das es funktioniert nicht. Das Heist der Pool konnte im winter einfrieren oder wenn ich das nutzen will, hat es keine warme Temperatur. Die Heizung war ein mal komplett Tot (das haben die zeitlich ausgetauscht aber nur mit 2kw leistung statt 4kw). Nach viel zeit und kämpfen habe ich wieder der richtiger 4kw Leistung. Aber der Ursache ist immer noch nicht bekannt und die versuchen es nicht zu lösen. der Pool ist nicht wirklich praktisch aufgebaut weil um der Heizung Sicherung wieder einzuschalten oder der Wasser abzulassen muss mann der ganze Seite abschrauben. Eine Revision klappe war im Verkaufs Gespräch versprochen aber niemals eingebaut. Die haben gesagt die werden es nachträglich einbauen. Aber das haben die nicht gemacht. Die Dämmung platten fallen auch ab und sind nicht fest, kein bodenplatte Dämmung und da sind viele luftlöcher zwischen platte und Gehäuse. Einfach Schlecht gedämmt und das kostet mir Geld immer wieder.

Automatic watering system using Gardena 1197 + OpenHab + Pilight

I was tired of having the repetitiveness of watering my garden every day so I wanted a solution to manage the garden watering. It was not as simple as just using one circuit because my garden is spread out, so different areas need different times and water pressure is a problem. I also did not want to dig my garden up to lay down new water pipes, so I wanted to be able to use my existing garden hose's.

The solution cost was to use Gardena automatic water distributor along with an single electronic valve from Hunter. This keeps the electrics simple and the connections plug and play. The control was done with openhab running on a raspberry pi, which triggered the valve via a remote 433mhz switch. You could obviously use a valve per circuit, but this requires another bridge to the PI and I had the 433Mhz already set up with pilight. As it is below you can also switch the valve with an electric pump, which I sometimes do when I have collected enough rain water.

Parts list:
1.) Remote switch - 25 Euro - Although I had this already
2.) Gardena automatic water distributer - 55 Euro
3.) 24 V AC Transformer - 12 Euro
4.) Hunter PGV-100 valve - 16 Euro - basically cheaper than Gardena version
5.) Raspberry PI - 40 Euro - although had this already as well
6.) Aurel 433Mhz transmitter
7.) Various garden houses to different sections of the garden, 4 circuits in use, but up to 6 can be used

Garden Distributor

The Gardena distributor works quite simply by switching to the next circuit when there is no water pressure for a certain period of time (I was using about 10 seconds). So with a on-off-on-etc pattern you can control up to 6 circuits with different time periods if you want.

Qt issue /problem with frameless window flickering on ubuntu

When using a frameless window in QML (prehaps directly from c++ as well) you need to manually allow dragging of the window. The first solution I found was like this:

Window  {
    id: appWindow
    flags: Qt.Window|Qt.FramelessWindowHint

    MouseArea {
        id: mouseRegion
        anchors.fill: parent;
        property variant clickPos: "1,1"

        onPressed: {
            clickPos  = Qt.point(mouse.x,mouse.y)
        }

        onPositionChanged: {
            var delta = Qt.point(mouse.x-clickPos.x, mouse.y-clickPos.y)
            appWindow.x += delta.x;
            appWindow.y += delta.y;
        }
    }
}

This worked on windows, but on Ubuntu the window flickered on Ubuntu due to a race condition:
Mouse move event A:
                Receive mouse position relative to app position Y
                Update app to position X

Mouse move event B:
                Receive mouse position relative to old app position Y (and not X as expected)
                Update app to position Z

The second effectively incorrectly does “double” the delta…


The fix is then to use a global cursor position as reference, so the new solution is then

Window  {
    id: appWindow
    flags: Qt.Window|Qt.FramelessWindowHint
    MouseArea {
        id: mouseRegion
        anchors.fill: parent;
        property variant clickPos: "1,1"
        property variant appStartPos: "1,1"

        onPressed: {
            // fetch global position due to bug on ubuntu
            clickPos = gApplicationController.getCursorPos()
            appStartPos = Qt.point(appWindow.x, appWindow.y)
        }

        onPositionChanged: {
            var newPos = gApplicationController.getCursorPos()
            var delta = Qt.point(newPos.x-clickPos.x, newPos.y-clickPos.y)
            appWindow.x = appStartPos.x+delta.x;
            appWindow.y = appStartPos.y+delta.y;
        }
    }
}

Note you need to set up a c++ class that gets the cursor position something like

class AppController : public QObject
{
    Q_OBJECT

    QQmlApplicationEngine m_engine;
public:
    Q_INVOKABLE QVariant getCursorPos();
}

AppController::AppController()
{
    m_engine.rootContext()->setContextProperty("gApplicationController", this);
}

QVariant AppController::getCursorPos()
{
    return QVariant(QCursor::pos());
}

Running ubuntu/linux on a xen server 6.5 with a passthrough GPU

For a while I was struggling to get ubuntu to work with my NVIDIA GPU in passthrough mode on xenserver. Xorg start, but then just fail... and those xorg messages are sooo helpful ;). Any way it turns out xorg could not correctly map the right driver to the correct PCI device. I had to add the PCI bus ID to the xorg.conf like here:

 BusID "PCI:0:12:0"

 Found this info here: https://wiki.archlinux.org/index.php/Xorg#More_than_one_graphics_card:

 my devices "lspci | grep -e VGA -e 3D":

00:02.0 VGA compatible controller: Cirrus Logic GD 5446

Temperature and Relative Humidity

Below is a plot of my measured temperatures and humitidy for my house over time. Data is collected from Oregon sensors over 433hz wireless transmission to the raspberry pi (with 433hz receiver) and stored in Google docs. The graph below is created with the help of highcharts using java script.

Curl C to google sheets

A quick post about using the CURL C API to upload data to google spreadsheets. I used it upload temperature and humidity data that I am tracking at home. There are a few steps

1.) create a google spreadsheet the normal way (with headings for each data item you want to save)

2.) get auth from google:
                curl_easy_setopt(curl, CURLOPT_URL, "https://www.google.com/accounts/ClientLogin");
curl_easy_setopt(curl, CURLOPT_FOLLOWLOCATION, 1L);
curl_easy_setopt(curl, CURLOPT_POSTFIELDS, "Email=YOUREMAIL&Passwd=YOURPASSWORD&accountType=GOOGLE&source=cURL&service=writely");

3.) Form your data in the correct XML format:
      sprintf(postData, "<entry xmlns='http://www.w3.org/2005/Atom' xmlns:gsx='http://schemas.google.com/spreadsheets/2006/extended'> <gsx:date>%s</gsx:date>  <gsx:time>%s</gsx:time>  <gsx:temp>%f</gsx:temp>  <gsx:relhum>%f</gsx:relhum><gsx:location>%d</gsx:location><gsx:device>oregon</gsx:device></entry>", 
dateStr, timeStr, s->getTemperature(), s->getHumidity(), s->getChannel());

4.) Post the data with the correct fields to the spreadsheet:
                        curl_easy_setopt(curl, CURLOPT_URL, "https://spreadsheets.google.com/feeds/list/YOURSPREADSHEETKEY/1/private/full");
curl_easy_setopt(curl, CURLOPT_POSTFIELDSIZE, strlen(postData));
curl_easy_setopt(curl, CURLOPT_POSTFIELDS, postData);
curl_easy_setopt(curl, CURLOPT_POST, true);

struct curl_slist *headerlist=NULL;
char authHeader[600];
sprintf(authHeader, "Authorization: GoogleLogin auth=%s", g_auth);
cout << "auth header " << authHeader << endl << flush;
headerlist = curl_slist_append(headerlist, authHeader);
headerlist = curl_slist_append(headerlist, "GData-Version: 3.0");
headerlist = curl_slist_append(headerlist, "Content-Type: application/atom+xml");

Modifying coova chilli to allow anonymous users for a private hotspot using automatic MAC addresses

So I spent a lot of time looking for a way to allow anonymous users to a coova chilli hotspot. Anonymous in the sense that a user can just click a button and get 30 min Internet access without having to type a password and what not. It made complete sense to use the MAC address as the users ID, but this only worked if you entered the MAC already. And NO where did I find that you could accept any new MAC address as a new user. Eventually I learnt enough about coova chilli to do this myself. The trick is to change the function dologin in the haserl script /etc/chilli/www/config-local.sh (use your password instead of XXXX) to

dologin() {
    res="$(echo "select username from radcheck where username ='$REMOTE_MAC';" | mysql -u root -pXXXX radius)"
    if [ "$res" = "" ]
    then
        echo "insert into radcheck (username, attribute, op, value) values ('$REMOTE_MAC', 'Cleartext-Password', ':=', 'password');" | mysql -u root -pXXXX radius
        echo "insert into radusergroup (username, groupname) values ('$REMOTE_MAC', '30min');" | mysql -u root -pXXXX radius
    fi
#    url=$(chi_login_url "$FORM_username" "$FORM_password" "$FORM_userurl")
    url=$(chi_login_url "$REMOTE_MAC" "password" "$FORM_userurl")
    cat <<ENDHTML
<html><head>
<meta http-equiv="refresh" content="0;url=$url"/>
</head></html>
ENDHTML
    wisprLoginResultsURL "$url" 
}

Once you have done this, every time a new device logs into your web page, the script will check if the MAC address exists or not. If not it will require any username. I changed my login page to just be a button and made the other fields hidden, like so edit /etc/chilli/www/login_form.tmpl :

<!--
  --  The login form
  -->

<div id="login-form">
<table>
<tr>
<!--  <td>Usernamebb</td> -->
  <td><INPUT NAME="username" VALUE="user1" TYPE="hidden"></td>
</tr>
<tr>
<!--  <td>Password</td> -->
  <td><INPUT NAME="password" VALUE="password" TYPE="hidden" TYPE="password"></td>
</tr>
<tr>
  <td colspan="2" nowrap align="center">
    <input type="submit" name="button" value="Login & Accept Terms">
  </td>
</tr>
</table>
</div>
