I am using device-modbus service to talk to a meter using Modbus TCP. I have subscribed to "edgex/events/#" to get all the events related to the device. However when I disconnect the device I am not getting any notification. Am I missing any configuration?
I can see in the logs for device-modbus when it says gateway path is no available. this is helpful for debugging but how can i get the disconnect notification
