[ISSUE] MQTT works only one way

[Aixx1]

Describe the bug
My device is successfully passing on its sensor data to HA, but HA cannot communicate to the Device.
I can see the messages going through in MQTT Explorer though.

To Reproduce
Action I used:

action: mqtt.publish
data:
  qos: "1"
  payload: "{\"wake\": true, \"wakeTime\": 180}"
  topic: wallpanel/mywallpanel
  evaluate_payload: true
  retain: false

I tried also with payload: '{"wake": true, "wakeTime": 180}', also with different commands like 'brightness' etc. Tried 'topic: wallpanel/mywallpanel', 'topic: wallpanel/mywallpanel/', 'topic: wallpanel/mywallpanel/wake' etc. but the phone doesn't wake up. Tried mostly while the screensaver was active, but also while screen turned off from the power button.

Smartphone:

• Device: Xiaomi Redmi A1
• OS: Android 12 (Go Edition)
• Application version 0.12.0 Build 0

I struggled with this too. You need to use the topic wallpanel/mywallpanel/command.
