How-to MQTT with WD

Hi

Im trying to use MQTT as well but I don’t get any data in graphs (use Grafana)

I did setup nodered (see att 1) you can see I have data in debug modus
You have to setup a database in influxdb ( i did but difficult to explaine see other posts about that)
I use grafana for graphs (see att 2)
you need to set it up as in att 3

My problem: no data whatever I try (see att4)

I got a lot of assist/help from Renato (thanks!) see here http://discourse.weather-watch.com/t/66430 but no result #-o
and yes a MQTT tutorial should be nice !

Maybe this is a little help
