Trouble shooting an automation

Trouble shooting an automation.
I set up a notification automation in Home Assistant for an Insteon moisture/leak sensor.
The automation is set trigger when the ‘State’ goes from ‘Dry’ to ‘Wet’ and send me a message that there is a wet condition. When I hit the “Run Action” button at the top of the automation the ‘message’ is sent. However, when I set the sensor on a wet towel, although the various lists (overview, Insteon, etc.) all show the ‘state’ of leak sensor is now “wet”, this change in ‘state’ doesn’t trigger the Automation and the message doesn’t get sent.

Check the actual states in Developer tools → States. The odds are that leak sensor is a binary_sensor which has the states on and off - wet is a translation for the human layer.
