Hey zusammen,
ich habe am Wochenende fleißig 3 verschiedene Leitungen für den Garten verlegt.
Einzeln lässt sich das ganze fein ansteuern. Hat jemand von euch einen Tip wie man das Smart lösen kann? Zigbee und WiFi wäre im Garten vorhanden. Nur finde ich leider keine passende Gerätschaft die hier zum Einsatz kommen könnte.
Hast du Ventile bzw. kannst du Ventile verwenden oder ist lieber ein “Bewässerungscomputer” am Wasseranschluss denkbar?
Hi, bei mir hab ich das so gelöst. Ein Ventil was über Z2M läuft, ein Feuchtigkeitsfühler, damit nicht unnötig bewässert wird. Das ganze ist dann mit den Wetterdaten gekoppelt und mit node-red automatisiert. Das Magnetventil ist Woox:
Hey Danke für die Antworten.
Bis jetzt fehlt mir genau ein Bindeglied.
Bis zur aktuellen Position liegt ein normaler Gardena-Schlauch. Ob ich hier nochmal einen Verteiler anbringe oder so, da bin ich total offen.
Auf der anderen Seite sind 3 Schlauchanschlüsse gegeben welche zum jeweiligen Bereich gehen (vorderer Garten / Hecke / Hochbeet)
Heisst im jetzigen Zustand. 1x 3-fach Verteiler für den Schlauch und 3x dieses Woox Magnetventil.
Anschließend kann man ja noch mit dem Feuchtigkeitsmesser spielen bzw. diesen ins System einbinden.
Ich stell hier mal den Ablauf in node-red rein dann kannst du ja sehen ob Du davon etwas brauchen kannst. Die Bewässerung läuft nur morgens und abends, damit das Wasser die Pflanzen nicht verbrennt.

Hallo Der-Eine,
ich habe ein ähnliches Unterfangen gestartet und bis soebend fertig geworden:
4-fach Verteiler von Gard**na, die Schläuche und Tropfer hast du ja schon, 4 Ventile von Sonoff, die mit den Metall-Schraubringen, die wirken etwas stabiler, als der Plastik-Kram.
Eingebunden habe ich sie über Z2M und dann meinen Wünschen freien Lauf gelassen!
Anstelle von Bodensensoren habe ich mir nämlich erlaubt eine Sonnen- und Regenlogik zu bauen in Abhängigkeit von Vorhersage- und Wetterstationsdaten. Eine Wetterstation eines NAchbarn kannst du bspw. über https://www.wunderground.com/ einbinden, wenn du nicht nur Vorhersagedaten haben willst.
Die Sonnenlogik kann stufenweise prozentual oder fest die Bewässerung verlängern, wenn z.B. 40 Grad erwartet wird von der Wettervorhersage bzw. tatsächlich gemessen werden. Da brauchen die Beete einfach etwas mehr, es gibt ja auch mehr Verdungstung. Die Regenlogik macht genau das Gegenteil: sie fährt am Tag des prognostizierten Regens bzw. wenn dieser tatsächlich fällt die Bewässerungsmenge zurück, bei mir z.B. um 50%, wenn 3mm Regen fallen, 70% bei 6mm und 100% ab 10mm Regen. Damit aber nicht genug, ich habe den Beeten individuelle Wasserfüllstände, wie eine Art Konto, gegeben, die von der täglichen Verdunstung wieder geleert werden. Somit kann ich also nach einem ausgiebigen Regentag sagen, dass - je nach Sonne und der Verdunstung - in den darauffolgenden Tagen immer noch nicht bewässert werden muss. Dazu werden die Beete einkalibriert, um ihre individuelle Beschaffenheit und Lage wiederzugeben.
Mit Bodensensoren wäre das sicherlich viel einfacher, denn ich muss jetzt noch die Bodenkalibrierung beobachten, damit die Beete möglichst genau auf ihre Begebenheiten hin angepasst werden und dies bei der “Kontoentnahme” berücksichtigt wird. Der Kalibrierungsfaktor ist grob dafür da, dass z.B. sandiger Boden anders speichert, als humoser oder lehmiger Boden. Bei mir ist bspw. ein Beet nah an den Pflastersteinen der Einahrt. Bei Sonne heizen sich die Steine schnell auf und trocknen das Beet besonders stark aus. Das will ich u.a. berücksichtigen.
Du siehst, man kann sich ziemlich verkünsteln 
So stelle ich die Beetbewässerung ein (hab Mushroom entdeck und komme davon nicht mehr los):
So stelle ich den Hitze- und Regenmodus ein:
Der aufmerksame Leser wird sich jetzt denken: hä? der hat doch 4 Kreise aber nur 3 Logiken im Bodenmodell? Ja, ein Kreis sind meine Topfplanzen, für die mache ich nur eine Hitzelogik, also mehr Wasser bei mehr Sonne. Bei Regen ist auf Grund der unterschiedlichen Topfgrößen kein allgemeingültiger Kalibrierungsfaktor möglich. Daher habe ich das der Einfachheit halber gelassen… (hab ich grad der Einfachheit halber gesagt?)
für mich noch wichtig ein Protokoll, damit ich immer sehen kann, warum was entschieden wurde.
Bin gespannt auf dein Feedback und weitere Anregungen aus der Community…
Hey, ich hab es bei mir (bis ich mal wieder etwas mehr Zeit habe) ganz rudimentär gelöst.
Ich werde um 20 Uhr per Push Nachricht am Handy gefragt ob die Bewässerung Morgen früh um 4 Uhr aktiv bleiben soll oder einmalig aussetzen soll. Dementsprechend wird Hochbeet, Gebüsch und Bäume jeweils mit Wasser versorgt. Es gibt bei jedem Bereich eine weitere Automation, die zb besagt, dass das Hochbeet nach 15 Minuten abgeschalten wird, Gebüsch und Bäume jeweils nach 30 Min.
Ich hab aktuell 8 Kreise mit Magnetventilen und Sonoff Ch4R3 Pro verbaut, mega. Mein WLan ist, aber innen und außen besser als zigbee oder BT.
bei mir laufen am Ende alle Sensoren - soweit sie dies unterstützen - nach MQTT. Fällt HA mal weg und ich entscheide mich für was anderes, muss ich “nur” MQTT anbinden. So habe ich es von Anfang an zufällig designed. Ich habe dazu einen SMLIGHT SLZB (zigbee2mqtt-Dongle) laufen. Den könntest du auch ins WLAN einbinden. Ich bin faul und nutze LAN und PoE, da ich keine Lust habe Stromleitungen für die Geräteversorgung zu legen. LAN-Kabel habe ich zu Hauf…
Ist alles eine Frage des Designs:-) und 8 Kreise zu steuern sicher auch keine leichte Aufgabe…
Gib mal ein paar Insights von deinem Bewässerungsmodell…
Das erinnert mich an meinen Start.
Ich nutze Gardena smart Home mit mittlerweile 8 Ventilen, 3x sonoff zigbee verteiler und Ecowitt Bodenfeuchtigkeitssensoren.
Ich glaube Bilder sagen mehr….. die Steuerung hab ich zweimal hintereinander. Ja ist direkt im Beet integriert und ich bin noch dran ein Abdeckung zu bauen.
Ca 200m Leitung in Summe
Verbaut sind Gardena OS140 für 1x12x3m und 1x für 9x7m
Rainbird für Beete und verschiede kleiner Rasenflächen (2-3 an einem Strang)
3x Hunter PGP-04 für die Rasenfläche von ca 12x12m
Und erweitert wird auch noch um mindestens 2 Stränge.
