After playing for a day with Node-Red installed on RPi along with MQTT server (broker) on the same RPi it turned out to be real fast and easy to port existing weather station information to a Dashboard.
Since weather station function provided by Perl - installation of Net::MQTT::Simple was necessary to connect to MQTT server.
A simple flow was created in about 1.5 hour. I have never worked in Node-Red before.
All data kept in-house.
