Hi folks, I have an ESP32 sending BME280 data to a Raspberry Pi that’s using MQTT as a broker and sending data to Node-Red. From Node-red I can create an Influxdb database. All are accessible from my local host. From the InfluxDB, I’m also able to create some graphs in Grafana at ‘localhost:3000’. I am stuck here since what I eventually want to achieve is publishing the graphs to my website outside my local network. In this case on my domain http://www.skynstars.com Any help here is much appreciated. Thanks. Jairo

Hi Jario,
Project code to post data to domain server.
Posting to domain server was inspired by this article by Stepen Borsey: Send ESP8266 Data to Your Webpage – no AT Commands!
There are two parts to the function; webInterface in my code. Webinterface function sends data to the domain server; then data is received by collectdata2.php, that is placed in the websites, public_html directory on the domain server.
collectdata2.php echoes back the data and sends”200″ indicating data was received successfully. Next collectdata2.php creates a new web page, every time data is received.
This is the page created at 15 minute intervals: Observations II
webInterface function
collectdata2.php
Hope you find this helpful with your project.
Regards,
William
