 -   **Window Covering.** These are blinds and shades. This was created in response to a request from a user who wanted to use "Siri open/close .." to control their automation, as opposed to "Siri on/off .." as would be required with switches.
 -   **Valve** - Allows you to create different types of valves: generic, irrigation, shower head, or water faucet.
 -   **Sensor.** Allows you to create different types of sensors. If configured in the Home app, sensors will generate notifications when their state changes in response to a detected event. Some types of notifications, classified as `critical` by Homekit, are allowed to bypass `Do Not Disturb` and some are allowed to appear in CarPlay. Sensors can be activated by different triggers. Currently, the options are:
-    - **Host Ping trigger.** Pings a network host. It is actvated after 3 failed ping attempts. The sensor resets when ping is successful.
+    - **Host Ping trigger.** Actvates the sensor after a configurable number of failed attempts to ping a network host. The sensor resets when ping is successful.
     - **Cron trigger.** Activates the sensor when the time and date match the schedule deascribed by the cron expression. The sensor resets after a brief delay.
     - **Switch trigger.** To trigger a sensor from a switch, create a switch with a companion sensor. A future release may provide the ability to create this pairing as a sensor with a switch as trigger.
