Toggle switch for RF bridge

Configuration
1

Hello,
I have a sonoff RF bridge flashed with tasmota and configured in HA using MQTT.
now I have ad a light switch to it in configuration.yaml

switch:
- platform: mqtt
  name: "Lamp Woonkamer"
  command_topic: cmnd/tasmota_EDEBDA/rfcode
  #availability_topic: "tele/tasmota_EDEBDA/LWT"
  payload_available: "Offline"
  payload_not_available: "Offline"
  payload_on: "#FFC7C0"
  payload_off: "#FFC7C0"

now this works, but since there is only 1 on/off button I would like to have only one button.
now I have 2.
also I do never know the current state of the device

So I tried always having the offlline icon. but it doesn’t work.

Does someone know how I can really use this one as a toggle device?
Thank you

ok,
I have created some kind of toggle function by using the entity as a button

  - entity: light.lamp_woonkamer_lamp
    type: button
    name: Woonkamer
    icon: 'hass:lightbulb'
    show_state: false
    action_name: "\U0001F387"

still not fully happy with the action_name, but for now I’m happy
