The HomePlate makes use of MQTT Discovery so it should automatically add its sensors to your Home Assistant instance if MQTT is already setup.
For example dashboard yaml see dashboard.md.
You can change the activity running on the HomePlate by publishing the following MQTT message to the topic: homeplate/<mqtt_node_id>/activity/run
which defaults to homeplate/homeplate/activity/run
T
You can add additional data to the action as well. To display an image:
{
"action": "img",
"message": "http://homeassistant.local:5006/1.png"
}
- service: mqtt.publish
data:
topic: homeplate/homeplate/activity/run
qos: '1'
payload: '{ "action": "img", "refresh": "300" , "message":"http://homeassistant.local:5006/2.png"}'
retain: true
