Been searching the net and I am not finding what I am looking for. I have multiple DS18B20 temperature probes connected to my Raspberry Pi 4B and looking for a way to have my Raspberry Pi 4B operate as stand alone data base logger, web server and email notification system directly from the Pi. All the guides/articles out there point me to websites such as or and they have some nice features such as temperature display charts and graphs as well as email notifications when a pre-determined temperature threshold is exceeded, but they are also $subscription$ based websites and I don't want to have to pay a monthly subscription fee for that functionality. I would like to ask if anyone knows of a program (for the Raspberry Pi) that offers a web server, database logging to access graphs/chart timeline via remote web browser and also email notifications when pre determined temperature threshold is exceeded ? Any help is greatly appreciated. Thank you.

I use influxdb on the pi for logging temperatures, and grafana (on the pi) to show graphs of that on a web page. Excellent, open source.
