 It is possible to publish to the MQTT topic using automations to update the button state using physical buttons for example (instead of using the UI button).
 
-The payload should be published to the relevant sensor. If you sensor is named `sensor.test_button` the topic should be `homeassistant/test_button`. For more information check out the Home Assistant [documentation](https://www.home-assistant.io/docs/mqtt/discovery/).

 ### Payload Example
 ``` json
 {"timestamp":"**timestamp here**","visibility_timeout":"2 hours","visible":true,"unit_of_measurement":"timestamp"}
 ```
+### Node Red Example
+```
+// Define entity_id
+const entityId = "sensor.test_button";
+
+// Get global object
+const haObject = global.get("homeassistant");
+
+// Get attributes object from entity
+let payloadObject = haObject.homeAssistant.states[entityId].attributes;
+
+// Get current timestamp in seconds
+const currentTime = Math.trunc(Date.now()/1000);
+
+// Modify timestamp in payloadObject.
+payloadObject.timestamp = currentTime;
+
+// Create string from object
+msg.payload = JSON.stringify(payloadObject);
+
+return msg;
