Shelly Flood Gen 4 in Home Assistant
After using Shelly flood sensors for a few years I’ve needed to add another one. This time a bought a Shelly Flood Gen 4 and noticed the difference to the old ones. So, here’s my code snippet to use them all via mqtt: alias: Benachrichtigung bei Wasser Sensor triggers: - id: Kueche trigger: mqtt options: topic: shellies/shellyflood-3494546A1B2C/sensor/flood payload: "true" - id: Waschmaschine trigger: mqtt options: topic: shellies/shellyflood-3494546D3E4F/sensor/flood payload: "true" - id: Heizkeller trigger: mqtt options: topic: shellyfloodg4-58e6c5A5B6C7/events/rpc value_template: "{{ value_json.params['flood:0'].alarm }}" payload: true conditions: [] actions: - metadata: {} data: title: Wassersensor {{ trigger.id }} hat Wasser entdeckt message: "{{ trigger.id }}" action: notify.email_markus mode: single The thing that cost me an hour of debugging: Use payload: true for gen4, not payload: "true".
