I try to reset narrowband but maybe I don't understand how this works.  
10 = PASS  
10 = PASS  
10 = PASS  
12 = BLOCK because change of value compared to last output is greater or equal to 1  
inject "reset" = to clear the stored value for all topics  
12 = should pass now....but it doesn't.....

You have set `msg.payload` to the string "reset" whereas you need to set `msg.reset`. It isn't clear from the help what you have to set it to, but I think setting it to boolean true would probably do it.

Even a blank msg causes a reset.

You don't need to use a change node, just format your inject node the same as my screenshot above.

@GeorgeX may not be using an up to date version of node red, so may not be able to set msg.reset in the inject node.
