Detach the Switch from the Relays and use Switchmode 1 with: Backlog SetOption114 1; SwitchMode 1

In Home Assistant I created a automation that switches off the Water Pump if it reaches the water limit:

alias: Turn Off when no Water
description: ''
trigger:
  - type: turned_off
    platform: device
    device_id: 1d46636bf8dcb966ae537d5bdb967b04
    entity_id: binary_sensor.switch1
    domain: binary_sensor
condition:
  - condition: device
    type: is_on
    device_id: 1d46636bf8dcb966ae537d5bdb967b04
    entity_id: switch.water_fountain
    domain: switch
action:
  - type: turn_off
    device_id: 1d46636bf8dcb966ae537d5bdb967b04
    entity_id: switch.water_fountain
    domain: switch
mode: single

The UV light on the original firmware turns off automatically after 5 minutes. I did a automation in Home Assistant to keep it that way

alias: Turn Off UV Light after 5mins
