Choose another way. Create SNMP GET (analog) element for reading code state from remote unit. Set the value for the thresholds so that the codes set into the normal range (just not distracted).
Create a "Math" virtual sensor for catch state number 7. Set the thresholds so that only the value of 0 match into normal state (Low warning level = -0.5, High warning level = 0.5). The rest thresholds will leave as it is.
...
Also create some Math sensors for another needed states. And combine them in the group.
Create notification, email for example. Use macro in text message for sending properly information. Here 216001 is a id of SNMP GET sensor (State Code Get). We read his value, and the name of the element that fetch to sending a message.
Add this email to group notification for state "Normal".
Now we have a group of elements each of which corresponds to the state when its value is 0 (state "Normal").
