#365 Is Power over Ethernet (POE) on the ESP32 any good? (New TTGO and Olimex boards available)

How should we connect devices to our home network? Wireless or wired via Ethernet? Do these new POE boards from TTGO and Olimex change anything? Interesting questions. Let’s have a closer look.
We all know: Wireless IOT devices are cool. But they have some drawbacks. This is why we want to look at the alternative: Wired IOT devices

I've used the Olimex board (ESP32-POE) for awhile and it's definitely my go-to ESP board for most projects. PoE is super handy.

At 280k wide, its a considerable front row. Glad I caught center seat!

Hi Andreas, again a superb video, clean, straight forward explanation of the stuff we need. Since I do use the ESP32 a lot I've always considered some wired projects but was to lazy starting research for the necessary software changes. No excuse anymore ;-) I run the same rule as you: if it has some importance I use wired Ethernet whenever possible; it is often a way more "set-it-up-and-forget-it" solution than using WLAN. And - Btw, I'm not too far away of running short on IP addresses in my home Class-C network already ;-)

6:52 min "Power over Internet" would be a great Idea! :)

Great video as always 👍😊
Thanks for sharing your experience with all of us 😊

It would be great to switch home automation on PoE for multiple reasons. Also, it will reduce the Wifi traffic a lot.
Thanks
Cheers ✨✌

Great video as usual! Thanks for your great work in every video! I wish you and your family Happy Holidays, Happy New Year and mainly great health and love in your life!

Andreas, for me this is a very valuable video. You have saved me a lot of digging. Thank you.
RE "not enough pins" another inexpensive tied in processor(ex. Arduino MIni Pro ?) can add pins if needed since power is not an issue.

Very well explained, as always! Thanks for sharing

[markuszingg]

Great! Left the ESP32 aside for the lackof wired ethernet!
As always great video! Thank you. 😃

Muchas gracias Profesor Andreas. Bendiciones, maravillosa explicación.

I think the ESD yellow sticker is only there to warn users of handling the product for Electrostatic Discharge, which can break electronic devices. I never saw POE devices warning about potential risk. 48v is not too risky in most scenarios (dry hands, not skin cuts).

4:01 I have never heard a better explanation of the wiring standard differences.

As always; Not disappointed with the content of your videos!!

I do think I'll stick to wireless for now.

I still use Cat5e for many applications, that is, as long as I have them in stock. It depends on the purpose and very important the distance. You'll be amazed of the speed over short distances. Usually I use Cat6, also for short distances. It works quite good. Why not prepare a video with distance/speed tests. Great video btw !

[christopherguy]

This is a good addition for the ESP32, having PoE on the board will make this very useful for stationary installations.

[OpenEmoto]

Just googled about the cable categories. Plain cat6 cable can support 10G up to 55meters. So, technically cat6, cat6a and cat7 can provide 10G ethernet. Great video!

Wired is all the rage and yea it is cool.. Thanks for taking wired into account. It is in many cases the best option. I try to look at it like a engineer should and figure out what the best solution is, but i am a bit wired biased. A matter of taste, experience and training i guess.

[giordanogobbo]

Very good video as always! Very good topic, i also searched a lot a way to use ethernet for my smart home and esp32 iot devices, unfortunately in my opinion esp32+ ethernet is not very common (yet), therefore is still too difficult to gather information and find cheap and good hardware ! Maybe it will change! Fingers crossed ;)

6:52 Power over Internet .... nice :-)
