Hi,
I am new to smart home thing but I have experience in IT. I want to create all connections wired and with POE. Which one do you think I should choose?
I have about 20 Olimex ESP32-PoE deployed. They are awesome!

Thats awesome! since i am new to this i have basic questions.
- how many (max.) sensors can i connect to one olimex unit?
- what kind of sensors should i choose for long term usage?
- i heard about mqtt . can i use it in olimex and should i ?
- may i use any kind of poe switch ?
- how to define IP adress to olimex?
Thank you mate…
-
depends on the sensors. You can also expand the io with an arduino mega connected to the esp via serial interface.
-
basically anything that works with arduino. but be aware, esp32 is a 3.3v platform, while arduino is a 5v platform. you might have to use voltage deviders or level converters.

I am using MQTT with it, but you could also use ESPHome

I used cheap TP Link PoE switches, but I am moving to Ubiquiti now. So, should work with all PoE switches.

Use DHCP.
