SOLVED: Reed-Relays with NodeRed and Raspberry Pi / Windsensor

General
1

Hi everybody,

I am new here and want to build a weather station for my garden with Node-Red.
But now I have the problem that I want to connect a wind sensor to the Pi and the counting of the reed relays/contacts does not work as I want it to.
With the help of a "timed counter" I wanted to count every second the number of closed/open contacts. Unfortunately I never get "0" out. This means in reverse that I will not get a value when there is no wind.
Does any of you have another idea?

Here is my flow:

Hi there,

problem solved - the node "msg-speed" (Link: https://flows.nodered.org/node/node-red-contrib-msg-speed) solved my problem exactly.

Best regards
