Function to write Netatmo measurement in Influx DB

[HaVi]

When this:

payload.devices[0].modules[2].dashboard_data.min_temp

is in my debug node then output in the debugger shows the correct min-temp:

15-7-2019 11:50:04node: 42184b89.07c674msg.payload.devices[0].modules[2].dashboard_data.min_temp : number
15

So I think I need a function or change to save the min-temp (15) in the database.

The relevant part from the complete message object coming from the Netatmo "get stations data" node is shown in the graphic below.
