Text on HA Dash. My feeder sends by MQTT a alternating text to HA a) Feedning b) Waiting

Configuration
1

Hi

On my fish feeder (Name Per) I use a timer that switch on and off a SSR relay, Its built on Arduino I send following:

Setup()
#define timerFeedTopic "per/timerFeed"
String  timerMsg;            


Loop()
Some if statement:

True:
        timerMsg = "Feeding";
        client.publish(timerFeedTopic, timerMsg.c_str());


False:
      String timerMsg = "Waiting";
      client.publish(timerFeedTopic, timerMsg.c_str());

yaml:

mqtt:
    sensor:
    - name: 'Per automatisk feeding'
      unique_id: per
      state_topic: 'per/timerFeed'
      unit_of_measurement: 'Text'

In HA I’m not shure if Sensor is correct defined, as it is per now I don’t manage to make a card that present the alternating text Feeding/Waiting

Can you help me in correct direction?

From MQTT explorer I see the messages:
Norwegian, but you get the Idea:
