+The following example sends a notification via pushbullet if a sensor is over a critical value:
+
+```yaml
+
+notify me:
+  platform: pushbullet
+  api_key: "API_KEY_HERE"
+  name: mypushbullet
+
+automation:
+  - alias: FanOn
+    trigger:
+      platform: numeric_state
+      entity_id: sensor.furnace
+      above: 2
+    action:
+      service: notify.mypushbullet
+      data:
+        title: "Furnace fan is running"
+        message: "Fan running because current is {% raw %}{{ states.sensor.furnace.state }}{% endraw %} amps"
+```
+
+If you also want a notification when it drops back down below that limit, you could add this as well:
+
+```yaml
+  - alias: FanOff
+    trigger:
+      platform: numeric_state
+      entity_id: sensor.furnace
+      below: 2
+    action:
+      service: notify.mypushbullet
+      data:
+        title: "Furnace fan is stopped"
+        message: "Fan stopped because current is {% raw %}{{ states.sensor.furnace.state }}{% endraw %} amps"
+```
