Hi I am having an issue with this current flow. I am using the flow from this website [https://github.com/cflurin/node-red-contrib-dsm/wiki/Operating-time](https://github.com/cflurin/node-red-contrib-dsm/wiki/Operating-time).

As you can see in the image above, The first image shows when I inject "off", the operating time and payload is still the same. But after that when I inject "reset", the operating time and payload becomes different.

Is there a way to continuously update the payload even if I inject the "off" or "reset". Cos I need the payload to continuously be updated to calculate my live OEE. (Cos I wanna calculate machine running %).

Machine Running % = (Machine running Time/ Total Working time) \* 100

Hi, Sure you can do it. Please, read the doc and try to modify the configuration.

In the method `reset` you have to set `msg.payload` and `output = true`

There is no magic in the dms, it's just javascript and some basics about state machine.  
I'd start learning javascript:

Hello,

My counter starts with the button.  
I want to start by adding extra time depending on the variable at each start.

Sample:

extra\_time=variable

button is pressed  
00:00:00+extra\_time
