I have a switch (or 3 actually) for my garden water sprinklers
- platform: mqtt
name: "WaterTuin_Voortuin_Moestuin"
state_topic: "WaterTuin/gpio/14"
command_topic: "WaterTuin/gpio/14"
payload_on: 1
state_on: 1
payload_off: 2
state_off: 2
optimistic: 'false'
retain: 'true'
icon: mdi:water
and en entities card
entities:
- entity: switch.watertuin_voortuin_moestuin
name: Voor- en Moestuin
- entity: switch.watertuin_bamboehaag
name: Bamboehaag
- entity: switch.watertuin_achtertuinhoek
name: Achterthuin hoek
title: Bewatering
type: entities
Is it possible to change the icon on the card to mdi:water when state is 1 and mdi:water-off when state is 2?
