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 find it interesting that someone would use a $5 board, and then add a $15 ethernet. I am working on a camera system, and have been testing data speed, the esp32-cam is real cheap, but wifi too slow. A pi zero also cheap and 5mp camera is great, but only usb2 which is too slow. I tested a pi4b with gigabit either, 100mB file xfer, 100 times faster than wifi. Even the usb3.0 on the pi4 was maxed at 20mB. While $35 for a pi4 seems like a lot, it isn't if you consider the total cost. I looking at ethernet because I have 50ft cable runs, which I can do with usb extensions but only slow. 100mB with 100ft cable is the solution. What you think?

@Andreas Spiess The esp32-cam is ok for my car theft security as it will just save the images on the flash for a short time, and xfer them later. But I have another project to integrate 3 or 4 camera images some 50ft away in real time. The Pi 4 at $50 is tolerable, but I really want it half that cost. been searching and searching for an alternative, no luck. Only thing ran across was $24 NanoPi Fire2A-LTS from china. 2 month ship and looks support is bad, you ever try any of their products? thanks, appreciate all you do!

I would not use the ESP32 for video. A Pi is much better in this respect. Wi-Fi, particularly 5GHz, should be fast enough for many WiFi applications on a Pi.

@Andreas Spiess Andreas thank you. The TTGO goes with its own additional board (CH340C) for flashing. This interface has already two usb, one mini and one C. From the various picture on internet, even on the official lilygo webpage sometimes the interface is connected from the bottom of the main board, sometimes from the top, but of course depending on the side you plug it in the pins will be inverting. In addition to this there is the usb port on the main board. My question was if it's needed to power the main board or it will take power from the interface. I searched documentation but I didn't find anything, also in your video you didn't show this connection details. Before 'cooking' one or both boards I was looking to hints and explanations.

Hi Andreas, thank you for these great instructional videos! I have a question: on which of your videos I can learn how to program this ESP32 ethernet and what software to use? I loaded your code on Arduino (Mac) but more than that I cannot progress. In the past I programmed Tasmota on Sonoff Basic using esp32 on Linux (CLI), but here I'm a bit lost. Than you in advance.

My personal philosophy. Anything acting as a server or running a server service daemon is always wired with a fixed IP# in a range not used by wireless router DHCP server as client range. Sensors over distance where wires access is hard such as inaccessible walls or expensive to run wires goes wireless. Sensors on tools and other occasional use devices is wireless, always on home automation wired. Security purposes such as cameras with large data to be streamed and recorded always on wires but completely seperated on its own private wired network separate from home internet network to not impact home users bandwidth. If your security solution needs internet access the security hub has two wires. One to home internet to get to internet access and second to private wire network to keep large video data off of the home internet network. Never video over wifi unless playing around. When serious use cases always isolate and shield your bandwidth from other people.
Andreas Spiess

One problem I encountered often when crimping network cables: Poor quality cables have conductors made from copper coated aluminum (CCA). I never was able to make cable that properly worked at 1 gigabit (100M worked, though). Once I switched to real copper cables, every single cable worked at 1Gbit, so I really think the CCA is to blame. Unfortunately it can be difficult to tell if it is real copper or CCA. I only realized after looking at the cut cable under a microscope. I will never again buy cable that does not have a propper data sheet! Also, thanks for kind of promoting the ESP's LAN interface! I also think that wired is in many cases preferable over wireless and I hope the support in the community for this will grow. Recently I wanted to upgrade my 3D-printer's webcam to LAN. Only when the ordered network PCB arrived, I realized that the camera interface and the LAN interface share pins. And, if i saw it correctly, at least some of these can't be assigned freely. So no LAN and camera interface at the same time... Or does anyone know a way out?
Random Dude
Random Dude 9 місяців тому
@Andreas Spiess I am glad i can contribute something. I guess the most important thing is to be aware of such cables and not buy them. Unfortunately many sellers on ebay advertise them as CCA Copper. Acually more than just an euphemism for aluminium with a few microns copper on it... BTW. I ordered my bad cable from a well established reseller that mostly has a good reputation and existed alrady long before ebay...

Another alternative are Ethernet W5100 shields for Arduino AVR platforms. One Arduino Uno plus Ethernet shield (without PoE) is half the cost of the TTGO POE Board. . There are also Ethernet W5100 shields with PoE but then there is no price advantage.
Andreas Spiess

You are right. For me, POE makes the difference because of the cabeling advantage.

important thing; wifi is half duplex. so it's 150Mb/s in one direction at a time, and only one device can typically transmitting at a time in any wifi network, which slows that down even further if multiple devices need to transmit at once. 100Mb/s ethernet is full duplex all the time!
Andreas Spiess

Good point. But maybe not very important for IOT devices because of low needs...

Cat7 is not an official standard and therefore not enforced in production, cat6a is an official standard and achives the same bandwidth, however for most consumer needs cat5e is more than enough much more flexible and simple to work with and much cheaper, so I would recommend using that for most projects, cat6 seems pointless to me as it barely just eliminates a little bit of cross talk compared to 5e. Ethernet is not necessarily rj-45, ethernet is a computer networking technology which is also used in fiber optics for example. Very glad to se Poe for esp32 and I'm excited to work with it.

@Andreas Spiess You can get 5e, 6 and 6a shielded by going for FTP cables instead of UTP, but they are generally more meant for outdoor use. Tesla cars use Bluetooth for their wheels pressure sensor now, but they might be a bit of an extreme :D

I have been told, that RJ-45 and cat cable are originating from AT&T Bell laboratories within the phrase "Premises distribution system". AT&T manufactured those components and cables with the name Systimax. The PDS contains also passive adapters for RS-232 and Token ring and coax video etc. PDS RJ-45 connector 2 center pins are because of RJ-11 phone connection.
Andreas Spiess

Good to know the history of the RJ45 connectors. The first Ethernet cables I know were coax with BNC connectors, if I remember right. In a daisy-chain configuration, not a star.

Thanks for a nice video. Btw, that sticker is not a danger label for your safety as 50V will not kill you but a warning that the device may be damaged due to ESD (electro-static discharge), i.e. the manufacturer can always claim ESD damage bcs mishandling. Honestly, all bare bone electronics are susceptible to ESD so I understand them. It is also very difficult to prove ESD damage.

I use some ESP (both types) for various home automation things - sensors etc. I use a cat5e cable for power delivery, poe config on the cable, with 12 volt currently (maybe i add / increase to 24v later). I only use a standard buck converter to go down to 5v for the esp, with of course the option to sue the original 12v for motors if needed. I could use standard ethernet when needed, or any bus protocol on fewer wires (which was my original idea), but the esp are way simplier. I plan to add a dedicated "Node" wifi network somewhat in the future for these, isolated from most of my normal network (except the Home assistant server of course) and no internet connection. But for now, the default wifi does the job. I never intent to use this cables for high speed transmissions (i have a normal cat 7 network for that), and cat5e is enough for even standard video cams. So in my opinion, this is a budget friendly diy solution (which also lets me experiment on power over cat and other things :) ) Sometimes the custom diy is better just because of the fun doing it and the stuff you learn :)

Hello Andreas, Could you please measure increase od power consumption of your router after connecting ESP based ethernet device? Few years ago I considered about building smarthome system on arduinos and ENC28J60 but I did not do it because these ethernet chips had high power consumption. At these days ESP8266 on wifi with deep sleep result in much lower consumption. With tens of connected devices every watt will be noticible on electricity bill.

Wifi alarm systems are too easy to jam. Cabling are sometimes to expensive, so I am pursuing laser signalling, with low power invisible lasers between nodes.Added advantage is of course the laser trip wires as well then. With the availability of cheap small solar panel lamps, the nodes can be hidden inside and power is not a problem for ESP's or HC-12's. When you want to hide something, do it in plain sight.

Your advice of getting a Ethernet cable tester is IMPORTANT. It is a must if you build and crimp your own cables, but beware that my experience is that about 5% of store bought cables can have problems. It is also amazing how many errors in wiring can go undetected in use, as Ethernet will drop speed down to establish a connection. There are wiring errors that can cause a 'bad day'. A tester is money well spent. Highly recommended.

I like to keep every device wired if possible. Wifi just ads too many variables to the mix. Is the password correct? Does it give me enough troughput? Did I set the correct channel? If it's down, is it because something is broken, forgot its settings or just currently trying to reconnect? With 2€ snakey boi from Amazon, I just plug it in and data transfer go brrrrrrrrr. But to each their own. I can imagine that the compatibility with the wife (not just the wi-fi, pun intended, kinda proud of it, actually) plays a huge role in prefering wireless networking too tho.

Just a comment regarding power consumption ... I agree that you don't need to worry about Deep Sleep, but power consumption could be something to pay attention. If you have a manageable PoE switch, you can get this information reading the values of power consumption per port. In that case, you can get a real number of power consumption per IoT device that you are using.

You are right, there are many ways of adding pins if you need.

Cat 7 cables are a scam. The RJ-45 connector only supports a maximum of 500 MHz and is therefore only suitable for CAT 6A. There is no RJ-45 connector that meets the CAT 7 specification.

The other really good difference with WiFi is reliability. WiFi can have loss of connection because of noise and other issues. Ethernet will be working as far as the cable is connected.

2:52 Hahaha, old school - I only learned about modbus from working with actual industrial equipment. The good thing there (and likely not a coincidence, I suspect people had the exact same train of thought as you did) is that modbus is also available over TCP :-)

The Cheaterman 9 місяців тому
@Andreas Spiess You are right, you didn't mention it by name, but you did show it on screen alongside RS485 when you said "a few years ago I would probably have thought about using such a bus for my home" :-) To be fair most IoT devices use TCP/IP, it would be impractical for most people to route separate RS485 wiring or to have a modbus server on their local network nowadays :-)

Hello Andreas, this subject is very important to me as I build my own home and design my own multisensors. I tried the Olimex, it is quite expensive but unfortunately it did not function well (intermittent issues, difficult to describe). The TTGO seems very annoying! It's too big for in-ceiling sensors, and the features are all wrong. I don't need SD cards, the board spacing doesn't look efficient, and why include a USB-C socket if it only provides power? (A CH340 is sooo cheap now and small as well)... my quest continues! I have been thinking about trying to make my own board for a long time now, like Freetronics but for ESP32 and more "barebones" (small as possible). My end goal is cylindrical multisensors that can be installed into ceilings. 3D printed of course. I think for now I will continue to use Arduino Nano, W5100 breakout, buck converter and PoE injection for this application! Anyway great video, I always enjoy watching your presentations.

@Andreas Spiess I have just seen the WT32-ETH01. It is *not* PoE, but does look interesting because it does have a lot of the features I am looking for: minimally small and ethernet!

As more and more motherboards have cheap Intel or Realtek 2.5GbE adapters, I predict that it will be the new standard for home in a few years and Cat5E cable is good enough for that. In my experience, storage and low end PCs cannot even keep up with >200MB/s transfers. Mostly because of encrypted protocols, spinning disks and cheap cache-less SSDs.

Bei dem POE Video letztes Jahr hast du aber eine andere Stimme gehabt....warst erkältet? Ich habe letztes Jahr versucht einen rpi3b+ mit cat7 Kabeln über Poe zu versorgen für eine OGN Station. Der Splitter mit 5V Micro USB Ausgang auf der rpi Seite hat aber soviel HF noise produziert, dass ich das wieder gelassen habe. Es kommt also immer drauf an, was man vorhat VG

Great video. I was already interested in the TTGO wESP32 now I am even more interested. Could you show us a setup for remote lights using wired connections (no fancy colored stuff like Philips Hue) that can be integrated into Home Assistant? For a while now, I've been searching for smartlights that can be connected through ethernet. As they don't exist yet, I hope this can be done using the TTGO ESP32. Could you give us an example of this project and how to achieve that?

Great intro to ethernet on the ESP32. My own experience has been that the older CAT-3 cables work perfectly well for IOT devices, because those devices don't have the processing power to utilize the faster ethernet speeds. Even ethernet chips like the Microchip ENC28J60 were fast enough for all IOT projects, and they aren't the fastest!
Andreas Spiess
Andreas Spiess 9 місяців тому
You are right for IOT only. For me, Ethernet is an neutral infrastructure which has to be independent and long-term.

Nothing beats the reliability and simplicity of a cable! I'm not so sure about power consumption though... you're going from solar and battery (on your other projects) to grid power. Definitely good for reliability, but what about the electric bill?
Ted McFadden

@Andreas Spiess True that. Potentially lower maintenance that way too, especially for sensors that run 24/7.

I think this has great potential. I’ve always wanted POE powered IOT devices. Now I just pass 24v over Ethernet cables to my devices for power only. The “cost” of 8 pins is too much, maybe Expressif will build it into the next chip. Also, I’ve heard of complications with Bluetooth and Ethernet, that needs to be resolved.
