Multiple ESP32s update data to a website

[cuongvd]

Dear All,
I already built 5 ESP-WROOM-32 boards to collect temperature and light status (on/off) of 5 locations.
Now I would like those boards update its data to my local website (hosted on my NAS) then I can view them on my phone or computer.

I'm new to this.
Please help me out.
Thank you so much!

Cuong.

What to do with the data once it gets to the web server is not esp32 specific. There are many ways to do backend processing from a HTTP server.

You could use an HTTP server with websocket on each node. The website connects to all 5 separately and receives the data on change (e.g. as JSON strings). Or let each node and your browser connect to an MQTT broker.
You will need to learn and experiment a lot…

If you would like to do this entirely on esp32, I can give you resources for that. I can't help you with your NAS.
