I found a solution with mDNS. The website I used is the following: It worked perfectly fine.


You might look into the AWS IoT Greengrass service. The Greengrass framework is specifically geared towards this type of architecture. The RasPi would be a IoT Greengrass Core device, and the ESP32s would be local IoT devices that communicate on the local network with the RasPi. The RasPi can be intermittently connected to the internet to transfer data ...


I found an answer to my own question - it's even official documentation. Right here is a guide of moving all data from SD-card to USB-device and then boot the boot files from SD bot all other files will be run from the SSD USB device. The link to the guide (work-around): [

On the other hand, the payment would be concerned....


The SDCard interface is extremely slow compared to a USB 2.0 hard disk on my RPI3Bs. So a USB 3.0 SSD on a RPi4B is going to be even faster (USB 3.0 is faster, SSD is faster).


Which is better, SSD or HDD? Obviously, an SSD drive which has connected to Raspberry Pi 4B's USB 3.0 port.
