3D model description

  1. Garten Bewässerung /Garden Watering mit TASMOTA / SONOFF WLAN Schalter

English below...

Achtung:
Es wird in dem Projekt-Vorschlag mit 220V gearbeitet - das bedeutet Lebensgefahr, wenn spannungsführende Komponenten mit Wasser in Berührung kommen. Ich lehne jede Verantwortung ab, bzw. empfehle Magnetventile, die mit Schutzkleinspannung arbeiten! Ansonsten muss darauf geachtet werden, dass beide Anschlussdrähte durch das Relais geschaltet werden, da sonst nicht sicher gestellt ist, dass auch bei ausgeschaltetem Relais die Magnetventilkontakte spannungsführend sind!! Die hier gewählte Schaltung stellt das sicher, dennoch sind die Anschlussleitungen im eingeschalteten Zustand spannungsführend! Auch die Schaltdose ist nicht VDE-konform also nicht für den Einsatz wie hier beschrieben geeignet! Es handelt sich also um eine Studie, die nicht zum praktischen Einsatz empfohlen ist!!

Ein Nachbau erfolgt auf eigenes Risiko und eigene Gefahr!

Der Schlauchanschluss hat an der einen Seite 1/2'' Zoll und an der anderen Seite Passend für den üblichen 13mm Gartenschlauch.

Der SONOFF DIY wird mit TASMOTA von der Cloud befreit und MQTT ertüchtigt.

Incredibly expandable and flexible.)

Die von den externen Relais benötigten 5V können von SONOFF abgenommen werden. Auch die logische Ansteuerung der Relais erfolgt über GPIO Pins des SONOFF. Hierfür muss die Konfiguration angepasst werden. (Generic 18)
Siehe Bilder.

Die 240V Starkstromschaltung funktioniert prinzipiell so, dass das eingebaute Relais des SONOFF DIY die eine Anschlussleitung schaltet, und die Schalter der Zusatz Relais-Platine die andere(n) Anschlussleitung(en).

Zusammenbau:
Die Aussparungen sind unterschiedlich breit, da der SONOFF etwas breiter baut.

Achtung, beim einstecken der Platinen in die Anschlussdose keine Werkzeuge verwenden, da sonst SMD Bauteile zerstört werden könnten! (BTW: Der Baustein R3 ist 5k groß :-) )

  1. garden irrigation /garden watering with TASMOTA / SONOFF WLAN switch

__Attention:
The project proposal works with 220V - this means danger to life if live components come into contact with water. I decline all responsibility, or recommend solenoid valves that work with protective extra-low voltage! Otherwise, care must be taken to ensure that both connecting wires are switched through the relay, otherwise it cannot be guaranteed that the solenoid valve contacts are live even when the relay is switched off!!! The circuit chosen here ensures this, but the connecting wires are still live when the relay is switched on! The switch box is also not VDE-compliant, i.e. it is not suitable for use as described here! This is therefore a study that is not recommended for practical use!

Reconstruction is at your own risk and peril!__

The hose connection has 1/2'' inch on one side and on the other side Suitable for the usual 13mm garden hose.

The SONOFF DIY is freed from the cloud and MQTT-enabled with TASMOTA.

The 5V needed by the external relays can be taken from SONOFF. The logical control of the relays is also done via GPIO pins of the SONOFF. For this, the configuration must be adapted. (Generic 18)
See pictures.

The 240V power circuit works in principle so that the built-in relay of the SONOFF DIY switches one connection line, and the switches of the additional relay board switch the other connection line(s).

Assembly:
The cut-outs are of different widths, as the SONOFF is slightly wider.

Attention, do not use any tools when inserting the boards into the junction box, otherwise SMD components could be destroyed! (BTW: The R3 component is 5k in size :-) )

Console Tasmota:
rule1 ON Power2#state=1 DO Power1 1 ENDON ON Power2#state=0 DO Backlog Power1 0; Power3 0 ENDON
rule2 ON Power3#state=1 DO Power1 1 ENDON ON Power3#state=0 DO Backlog Power1 0; Power2 0 ENDON
