MQTT automation triggers 20-30 times?

I’m using the following automation to trigger an MQTT command to refresh my owntracks. Looking at the MQTT Broker, when the automation triggers, every 5 minutes, I get a barrage of publishes, 20-30 times before it stops. I would think it would just send the message once. Anyone know what’s going on?

automation:
# REFRESH OWNTRACKS #
  - alias: Refresh Owntracks Jim
    trigger:
      - platform: time
        minutes: '/5'
    action:
      - service: mqtt.publish
        data:
          topic: "owntracks/jimphone/phone/cmd"
          payload_template: '{"_type":"cmd","action":"reportLocation"}'

Never mind, reading is hard :slight_smile:
Had to specify Seconds: 00 or it triggers 60 times. RTFM.
