"break" informationen possible?

Hello!

 

I upload with my own system all data. If the controller are down (for maintenance or something else), it would be great if i can send a "break" signal to emoncms.

Because the line should be broken and I can see later, there are missing values.

Not sure if it is planned in the charts, but would be fine.

Also a problem is when I upload the nodes and not all datas are available (restart of controller and has to wait until data are arrived), I HAVE to send data´s.

So I send for unknown the value Zero ... but this will show in the chart. Also there would be great if I can set "broken" ... then the value will be ignored and no chart are display the data.

Thank you!
