Home Assistant Integration
Custom Integration (recommended)
A full custom integration with config flow, device registry, and a water_for service is included in the homeassistant/ directory.
See homeassistant/README.md for installation and usage.
YAML-only (built-in MQTT platform)
payload_on can also contain the duration of the pump in ms.
switch:
- platform: mqtt
name: "Irrigation Pump"
command_topic: greenhousino/pump
state_topic: greenhousino/pumpstate
payload_on: "on"
payload_off: "off"
state_on: "on"
state_off: "off"
availability_topic: greenhousino/pump/status
payload_available: "online"
payload_not_available: "offline"
qos: 1
For duration-based watering via YAML, use an automation:
automation:
- alias: "Water for 5 minutes"
action:
- service: mqtt.publish
data:
topic: greenhousino/pump
payload: "300000" # 300000 ms = 5 minutes
