MQTT is great for monitoring, it gets sent to the Pi then node red sends it to the web as well so FRED can make a chart for viewing anywhere.
That sounds great Paddy. 12V to Vin - wow I wasn't aware this is working. Which board exactly are you using?
In my home environment I'm using http to send the data. Got some webspace running php and mysql. The ESP transmits the data via a simple GET request to a PHP script, which saves the data to a MySQL DB. The server is running anyways so I'm saving the local Pi/Mosquitto and wont have to use cloud MQTT. I like to keep my data for myself
For security I'm using simple HTTP_AUTH.
When I'm running the Pi I can easily connect node-red to the database and when I'm on the way I'm using a little website I've set up to view the data.
