 ### Sensor
 
-The following sensors are added for each Starlink system:
-
 - Ping - The ping that Starlink has measured, in ms
 - Azimuth - The direction Dishy is facing in degrees
 - Elevation - Dishy's current elevation in degrees
 - Uplink throughput - The amount of data being uploaded through Starlink in Mbit/s
 - Downlink throughput - The amount of data being downloaded through Starlink in Mbit/s
 - Last boot time - The time Starlink was last turned on
+
+### Binary Sensor
+
+- Obstructed - Whether Dishy is currently obstructed
+- Roaming - Whether Starlink is "roaming". Roaming is an optional upgrade that allows you to use your Starlink outside of your home address. It is also known as "portability"
+- Heating - Whether Dishy is currently heating. This may be due to cold temperatures, or an attempt to thaw snow and ice
+- Idle - Whether Starlink is in an "idle" state to save power
+- Mast near vertical - Whether Dishy is mounted straight
+- Motors stuck - Whether Dishy is unable to move
+- Thermal throttle - Whether Starlink has reduced performance to avoid overheating
+- Unexpected location - Whether Starlink has detected operation outside of its designated area
