 This example combines multiple CO sensors into a single overall
 status. When using templates with binary sensors, you need to return
-`true` or `false` explicitly. `entity_id` is used to limit which
+`true` or `false` explicitly.
-sensors are being monitored to update the state, making computing this
-sensor far more efficient.
