+Then you can make a sensor that detects the latest version of Tasmota and alerts you if there is an update.
+From my configuration.yaml
+```

+              }}
+```
+Note the above is for 2 switches.
+
+In customize.yaml
+```
+binary_sensor.sonoff_update_available:
+  friendly_name: Update Available Sonoff
+  device_class: problem

+Then it will show as an alert icon that you can show in Lovelace.
