    Wetterstation (Verkauf)

    in Hardware

    Geschrieben

    Hallo,

     

    Mangels Zeit für die Einarbeitung verkaufe ich meine Wetterstation:

    - Weather Station Starter Kit in transparent

    - Step down power supply

    - DC Jack Adapter

     

    Die Wetterstation wurde mit einem Raspberry Pi autark betrieben.

     

    EUR 90 zzgl. Versand stelle ich mir vor...

     

    Bei Interesse gerne melden.

     

    RED Brick Fragen

    in Anfängerfragen und FAQ

    Geschrieben

    Hallo,

     

    Derzeit überlege ich (immer noch), den RED Brick einzusetzen...

    Ich möchte den Brick gerne via Netzwerk ansprechen, nicht über USB.

    Würde ich einen WiFi-Adapter am USB-Port betreiben, so gehe ich davon aus, dass dieser ständig in strahlender Verwendung wäre, wenn auf dem Red Brick beispielsweise OpenHAB laufen lassen würde.

     

    Die Ethernet-Extension hingegen empfinde ich mit Euro 40 als eher zu teuer.

     

    Weiß vielleicht jemand, ob es ggf bald eine RED Brick mit Ethernetport gibt? Gibt es anderenfalls ggf. einen unterstützten USB-Ethernet-Adapter?

     

    Kann da jemand etwas zu sagen?

    TF Wetterstation instabil

    in Anfängerfragen und FAQ

    Geschrieben

    Hallo,

     

    Seit einiger Zeit betreibe ich die TF-Wetterstation mit dem Beispielsscript (Python) mit dem Raspberry Pi 2. Gespeist wird das System durch die lt. TF-Wiki vorgeschlagene Kombination mit DC Jack Adapter und Step Down.

     

    Nun habe ich dem Raspberry eine unterbrechungsfreie Stromversorgng spendiert, die wiederum vom Raspberry gespeist wird.

     

    Der Raspberry friert nun nach einigen Stunden Laufzeit das Display der Wetterstation ein und ist auch komplett nicht mehr (über ssh etc) ansprechbar.

     

    Kann es sein, dass die Stromversorgung (MW-Netzteil mit 3A am Ausgang und derzeit auf 9V eingestellt) das Problem darstellt?

     

    Mich wundert dann nur, dass der RPi bis dahin 10-20 Stunden problemlos lief.

     

    Vielleicht hat ja jemand eine Idee, warum das Gesamtsystem nach Stunden jeweils den Dienst versagt...

     

     

    Python-Script abbrechen und Display aus

    in Anfängerfragen und FAQ

    Geschrieben

    Es ist merkwürdig... habe es angepasst.

     

    Jedoch, der RPi friert zur Schalt-Uhrzeit (22 Uhr) komplett ein und reagiert nicht mehr. Habe eine unterbrechungsfreie Stromversorgung angeschlossen, die den RPi herunterfährt, wenn ich den Strom trenne (da der RPi ja nicht mehr erreichbar ist). Ggf. sagt das ja jemandem etwas, dass dieses noch agiert, wobei ich nicht genau sagen kann, ob es dann tatsächlich den RPi noch herunterfahren kann oder dann nach eingestellten 90 Sekunden simpel den Strom trennt.

     

     

    Python-Script abbrechen und Display aus

    in Anfängerfragen und FAQ

    Hi,

     

    Ich habe die Einrückungen korrigiert... ich bin dermaßen wenig daheim, dass ich keine Zeit finde, mir Python anzueignen, was sich ändern soll. Derzeit möchte ich einfach nur das Display zu bestimmten Uhrzeiten schalten, damit es daheim bei der Familie nicht nervt.

     

    Die Einrückungen haben funktioniert, das Script läuft.

     

    Allerdings, zur angegebenen Ausschaltzeit läuft der Pi weiter, das Display friert jedoch ein und wacht auch nicht mehr auf.

     

    Den folgenden Code habe ich ohne Besserung geändert:

    lcd.backlight_off()

    in 

    self.lcd.backlight_off()

     

    Vielleicht weiß ja jemand den entscheidenden Hinweis um dieses Problemchen zu beheben,

    Python-Script abbrechen und Display aus

    if __name__ == "__main__":
    log.info('Weather Station: Start')

    weather_station = WeatherStation()

    if sys.version_info < (3, 0):
        input = raw_input # Compatibility for Python 2.x


import time

while 1:
    ts = time.localtime()
    if ts.tm_hour == 22 and ts.tm_minute == 0:
        lcd.backlight_off()
    if ts.tm_hour == 6 and ts.tm_minute == 0:
        lcd.backlight_on()
    time.sleep(50)

    if weather_station.ipcon != None:
        weather_station.ipcon.disconnect()

    log.info('Weather Station: End')

     

    Habe es nun dort eingefügt...

     

    Nun startet das LCD tatsächlich beim Start des RPi und zeigt Werte an, jedoch unter einer Minute, denn dann friert das Display ein, während der RPi normal weiter läuft.

     

    EDIT:

    Nein, das Display läuft weiter, passt die Werte anfangs sekündlich an, dann scheinbar 1 x / Minute.

    An welcher Stelle würdest Du es einfügen ?

     

    Ich frage mich, warum das alles unter Raspbian Wheezy nicht notwendig war. Das lief problemlos...

     

    Wenn es hilft, wäre das ja super.

    Python-Script abbrechen und Display aus

    in Anfängerfragen und FAQ

    Geschrieben

    Hallo,

     

    Momentan werkelt mein Tinkerforge-Wetterstations-Kit in Zusammenarbeit mit einem Raspberry Pi 2 und dem Standard-Wetterstations-Beispielcode.

     

    Noch immer nicht habe ich Zeit finden können, endlich Python zu lernen.

     

    Was ich momentan einfach nur ändern möchte, ist, dass die Wetterstation nachts ab 22 Uhr bis morgens 6 Uhr das LCD-Backlight ausschaltet...

     

    Im Grunde müsste man doch in Python eine Uhrzeitabfrage einfügen können, die die Zeit prüft und das Backlight eben dann aus- und 1x/Tag wieder einschaltet.

     

    Oder ist ggf. ein cronjob machbar, der das Script nachts beendet und morgens startet ? Aber dann würde das Display eingeschaltet bleiben.

     

    Vielleicht hat ja jemand eine kurze Idee, die ich übergangsweise schnell nutzen könnte. Bis ich soweit bin, hat meine Frau sich zahlreich über das ständig leuchtende Display zu oft beschwert.

  File "/home/pi/tinkerforge/wetter.py", line 167, in <module>
    input('Press key to exit\n')
EOFError: EOF when reading a line

     

    Habe ich in rc.local eingebaut...

     

    Nutze ich statt dem sudo-crontab doch den Benutzer-crontab, so startet das Skript auch nicht.

     

    Muss ich Pfade setzen ? Wenn ja, wie ?

    Tinkerforge-Python-Script ohne Autostart (Raspbian)

    Hi,

     

    Derzeit betreibe ich die Tinkerforge-Wetterstation per Raspberry Pi 2.

    Nun habe ich das System neu aufgesetzt, dabei diesmal aber statt Rapsbian Wheezy das neuere Raspbian Jessie hergenommen.

     

    Brick/d/v sind installiert. Starte ich "python /home/pi/tinkerforge/wetter.py" (Wetterstation-Standard-Beispiels-Script), so funktioniert alles wunderbar.

     

    Um nun das Skript beim Start des RPi zu laden, habe ich zwei Varianten getestet (was zuvor unter Wheezy tadellos funktionierte):

     

    1) sudo crontab -e, dort eingetragen:

    @reboot /usr/bin/python /home/pi/tinkerforge/wetter.py

     

    2) sudo nano /etc/rc.local, dort eingetragen:

    python /home/pi/tinkerforge/wetter.py &

     

    Obwohl ich mit selben Befehlen das Script starten kann, funktioniert nicht der Autostart mit obigen Lösungswegen...

     

    Ein User eines anderen Forums hat dies getestet und folgendes festgestellt:

    "/usr/log/brickd.log[script]2015-10-10 12:02:44.221968 <I> <network.c:373> Added new client (N: 127.0.0.1:60812, T: plain-socket, H: 17, A: disabled)

    2015-10-10 12:02:44.306278 <I> <client.c:220> Client (N: 127.0.0.1:60812, T: plain-socket, H: 17, A: disabled) disconnected by peer[/script]"

     

    Mir ist absolut nicht klar, warum sich a) das Skript manuell starten lässt, nicht aber automatisch und b) alles unter Raspbian Wheezy problemlos funktionierte...

     

    Weiß jemand Rat ?

     

     

    Wetterstation und RED Brick

    in Anfängerfragen und FAQ

    Geschrieben

    Würde vorsichtshalber gerne nochmals fragen:

     

    Ich kann also die Stepdown-Variante der Wetterstation (die aufgrund des bisherigen Raspberry verbaut ist) nutzen und Stepdown->Red Brick->Master stapeln. Dann wäre ein externes Netzteil, wie bisher, notwendig.

     

    Oder ich entferne die Step-Down-Variante und staple Red Brick->Master. Dem Red Brick verpasse ich einen Wlan-USB-Adapter und versorge die Wetterstation dann per Red-Brick-Micro-USB per 5V 1A Apple-Netzadapter.

     

    Bei Variante zwei kann ich die Step-Down-Variante und somit Platz sparen. Spricht also alles hierfür?

     

    Zum Brick wäre meine Frage noch:

    Aktualisiert sich das OS-Image des Red Bricks automatisch oder muss man es bei jedem OS-Update komplett neu einspielen, sodass alles individuell veränderte gelöscht wird?

     

    Da ich noch nicht programmieren kann, frage ich mich, wie einfach man die Wetterstation per Brick Viewer einstellen kann, also ggf Meldungen per E-Mail etc.

     

    Und, ich möchte mein Homematic und Philips Hue gerne in OpenHab auf dem Brick einbinden. Ist dieses und dessen Steuerung ohne Programmierkenntnisse möglich?

     

    Vielleicht kann ja jemand helfen...

    PoE ist eher nicht zu realisieren hier...

     

    Ich kann dann DC Jack Adapter und Power Supply entfernen und RED-Master-Ethernet stapeln und einbauen ?

     

    Dann kann ich künftig via Netzwerk auf den RED zugreifen ?

    Klasse...

     

    Einen RSS Catcher wie Fever, der momentan auf dem Raspi läuft, kann man nicht zufällig auf dem RED laufen lassen?

    Hm...

     

    Ich möchte doch openHAB auf dem Red Brick/Wetterstation betreiben.

    Das funktioniert doch nur über Ethernet/WLAN? Deswegen wundere ich mich, dass niemand auf die Ethernet Extension hinwies/einging.

     

    Ich muss also den RED Brick via USB am Mac anschliessen, das Image auf die microSD aufspielen und kann diesen dann in der Wetterstation mit Ethernet verbauen?

     

    Nur, ich mag kaum glauben, dass in die Wetterstation der Master Brick, Red Brick, DC Jack und Power supply sowie Ethernet Extension passen... Hat das jemand schon erfolgreich getestet?

    Wetterstation und RED Brick

    in Anfängerfragen und FAQ

    Geschrieben

    Das ist mir noch nicht ganz klar...

     

    Entferne ich den Raspi und ersetze diesen durch den RED Brick, dann staple ich 1) step down power supply/dc jack adapter, 2) RED Brick und 3) Master Brick.

    Den RED Brick verbinde ich dann mit dem USB Kabel.

     

    Nun will ich aber die Wetterstation mit dem RED Brick niemals per USB mit meinem Mac verbinden, sondern möglichst via Ethernet/Brick Viewer auf die Wetterstation zugreifen. Dann brauche ich doch einen Ethernet Extension Master ? Wie soll die Wetterstation sonst ins Netzwerk gelangen?

     

    Und, schaue ich auf die Wetterstation, so kommt es mir vor, als reiche die Tiefe nicht aus, um Step down, RED Brick und Master Brick im Gehäuse zu stapeln?

    Wetterstation und RED Brick

    in Anfängerfragen und FAQ

    Geschrieben

    Hallo,

     

    Seit einiger Zeit betreibt ein Raspberry Pi 2 meine Tinkerforge Wetterstation.

     

    Nun würde ich gerne den RPi2 gegen ein(en) RED Brick austauschen, einfach aus Interesse.

     

    Manches habe ich dabei noch nicht verstand und möchte deshalb mal fragen:

    - wie greife ich auf einen RED Brick zu ohne Bildschirm? Per SSH? Via Ethernet und dem Viewer ? Ist dann ein Ethernet Extension Master notwendig?

    - kann ich die bisherige Hardware belassen zur Stromversorgung (step down power supply und dc jack adapter)?

    - und da ich gerade etwas python lerne: man kann via python-Skript dann beispielsweise das Display der Wetterstation nutzen ?

     

    Mein Ziel ist:

    Wetterstation im Betrieb mit RED Brick zur Ausführung von openHAB. Außerdem möchte ich noch die 4 Buttons mit der Wetterstation verbinden, die Tinkerforge anbietet, um dort neben Wetterdaten eben weitere Meldungen anzeigen zu lassen.

     

    Kann jemand kurz helfen?

    Ja, da schmeiße ich wohl was durcheinander...

     

    Mittlerweile gibt es folgendes zu vermelden:

    Ich habe python setup.py install fehlerfrei ausgeführt. Das .egg lässt sich weiterhin nicht installieren mit gleichem Fehler.

     

    Im Verzeichnis des Scripts befindet sich das tinkerforge-Verzeichnis mit den benötigten Dateien *.py.

     

    Heisst, schreibe ich im Script vor den genannten Zeilen wie ip_connection nun tinkerforge.ip_connection, so laufen nun die Scripte.

     

    Aber am liebsten wäre mir, wenn sich das .egg im System installieren würde.
