10 € Wifi Plug als virtuelles Gerät in homee steuern
10€ WiFi-Steckdosen in homee – NodeRed Projekt
Günstige WLAN-Steckdosen /Plugs in homee einzubinden ist seit jeher immer mal wieder Thema. Im Bereich der anderen Funkstandards gibt es nicht immer gute Alternativen:
Zigbee: Funk ist mir zu störanfällig, die Osram Plugs sind günstig, aber sch****. Zwave: Da gibt es einige Möglichkeiten, allen voran Fibaro. Gerade günstig sind die nicht und mit der Zwave Zuverlässigkeit hapert es insbesondere in Gruppenschaltungen. Enocean: Nach dem Rückzug von Permundo ist die Auswahl doch sehr begrenzt und teuer ist Enocean sowieso immer.
Also was tun? WLAN-Steckdosen gibt es wie Sand am Meer, man braucht nur mal bei Amazon zu suchen. Von Design und Größe her, gibt es auch ansehnliche und kompakte Plug. Der Preis um 10 € ist top.
Nach etwas Recherche, habe ich herausgefunden, dass viele dieser Firmen, die WLAN-Plugs anbieten (Gosund, BlitzWolf, Teckin, Meross, Homecube, usw.) die tuya Api verwenden.
Tollerweise gibt es in NodeRed einen node, der diese Api unterstüzt. https://flows.nodered.org/node/node-red-contrib-tuya-smart Es wird auch genau beschrieben, wie man an DeviceID und DeviceKey kommt (diese brauch man zur Ansteuerung).
Hat man schon einen Raspberry Pi mit NodeRed laufen, ist die ganze Sache relativ simple. Man benötigt für das unten genannte Vorgehen:
- node-red-contrib-tuya-smart -> Einbindung der WLAN-Plugs in NodeRed
- node-red-contrib-enocean -> virtuelle Enocean-Geräte in home (Danke an @micha und Holger-Will)
- Enocean-Stick am Pi
A.) Erstellung virtueller Enocean-Geräte in homee:
Diese werden auf Basis von Nodon 1Relais (Enocean) erzeugt, die nur die Funktion on/off haben.
B.) Kopplung dieser Geräte mittel des enocean-js node (https://github.com/enocean-js/enocean-js/tree/master/packages/node-red-contrib-enocean) mit den Wifi Plugs.
