Micro USB Ethernet/PoE Adapter(U6113)

I was looking for something convert some of my Google Chromecast audios to Ethernet with power over Ethernet from wifi. This was one of the recommended adaptors for this use case I read about. So far so good. I plugged in this adapter and plugged one of the Chromecast I wanted to convert into this adapter. Then I reset the chromecast. Everything is working as it should. The Chromecast works without wifi now. Perfect connectivity and adequate speed so far. No issues with the power supplied. Seems to be compatible with the chromecast audio. No complaints for far. Recommend for this use case. Wish it was a tad cheaper.

Contrary to other reviews, this device DOES provide both power and data simultaneously via the ethernet port to the USB connector -- POE. It works as it's advertised to work. Power can also be injected via the secondary USB port using a conventional USB brick if POE is not available. Data can still be provided via ethernet. It's a great solution for Wyze cameras that are using third party firmware for ethernet connectivity and RTSP streaming. It does NOT provide ethernet capability to stock Wyze Cam firmware, though it will still power them via POE for long distance locations. If you understand how poe works, this should work for you. Good luck with yours!

I bought five of these things to hardwire our Google Home Minis into the ceiling, powered and data'd through our Ubiquiti USW-24POE. I pulled the cables and tested them, then plugged this thing into the Home Mini and then into the Cat6a cable. Both lights lit up, and the Home Mini booted. I factory reset it using the bottom button and started setup, but could not get the Home Mini to see the ethernet adapter. The switch did not show the device plugged in, in fact didn't see the Mini at all until I added it to the wifi, where it stayed connected even with the adapter plugged in. In the process of installing it, the MicroUSB connector bent slightly. It still provided power, but thinking it was the cause of the issues I crawled back up in the attic and swapped it for another of the 5 I ordered. Went back into the house, plugged in the Min and repeated the process, but still no Ethernet. Maybe I broke the first and replaced it with a faulty unit? Maybe they're both faulty? I took the first unit and plugged it into a 1st gen Chromecast, which took power instantly and booted up but again never joined the wired network. It is entirely possible that this is all Google's fault for their idiotic setup procedure that seems to require you to set up WiFi, or it's possible I got a faulty unit and broke one. I'll keep trying and they'll keep 3 stars for doing 1/2 of what they say they'll do.

TL;DR: Power is unstable and device reboots every 2-3mins without network load. I've been building out my home automation system using microcontrollers and SBCs, and I've been looking for a way to power everything over PoE and avoid wireless. Using a $5 RPi0 + a $20 USB PoE adapter is cheaper than a wESP32 solution and gives you a lot more room for a network stack and a lot more power/versatility. Building PoE relay/sensor hubs like this seems just about perfect for me. This device saves a lot of space inside an enclosure when you don't have to make room for a PoE splitter/power supply and a USB ethernet adaptor. These things are a great idea and I'm surprised there aren't more vendors that make similar. I really wanted this to work and probably buy a bunch of em. The issue I'm having with this PoE adaptor is pretty weird tbh... I've got a fresh, working RPi0 (v1.3) running the newest RPiOS/Raspbian powered by this PoE adaptor, which is plugged into a 10/100 8port PoE+ unmanaged switch. There are no other peripherals, USB(OTG) hubs, nothing connected to the GPIO pins, or any additional draw on the power rails -- just the Pi0. The Pi0 boots without power warnings and I can ssh into it. Looking through syslog / persistent journal / dmesg, I can see the kernel (5.10) finds and brings up the eth0 interface for the RTL8152 without issue. There are no errors, warnings or any signs of a problem anywhere in the logs. Device looks fine over USB with nothing anomalous. There is no packet loss or net errors. Temps are fine (33c with sink). Core voltage is normal. So far, so good... But, after 2-3 minutes of just sitting there idle, the Pi0 loses power and goes into a reboot cycle. Here's the strange part: It only happens after the network has been idle / low utilization for 2+ mins. It will constantly reboot with an open ssh connection, but NOT if I run top or glances that generates non-ACK traffic over eth0. Also, if I constantly ping the device from another machine it never reboots / loses power. I've tested this up to 15+ hours of constant pinging, and every time the ping / traffic stops, the Pi loses power within 2-3 mins. I've enabled persistent logging and there's nothing in the logs at all to indicate what the problem might be. It's clearly an unclean shutdown with no warnings. Monitoring the voltage on the 5v USB rails just shows the power dropping out and coming back up within around ~0.75 seconds. I can run a high cpu load (stress) on the Pi, but it will always reboot unless there is ALSO a significant network load (i.e. constant pinging from another device.) I suspected a low-power-state condition. I've tried disabling automatic power management of the device via sysfs config, and using ethtool to disable EEE (Energy Efficient Ethernet) but no love. I've even tested on a different (working, unmanaged) PoE switch. Same thing. The PoE device just keeps suddenly powering off without enough network load. Now if I power the same Pi0 with a standard 1.0a PSU and use a non-PoE network switch, it stays rock solid and never generates any errors regarding the RTL8152. The device seems to work fine as a ethernet adaptor alone, but the PoE function has been completely unreliable for me. Not sure if I've got a defective unit, or if there's some design flaw at fault here. I've reached out to UCTRONICS and I'll request a replacement. I'll update my review if this gets resolved.

I'm using this to both power and feed data to a Chromecast. It's nice to get these devices off of my 2.4 GHz spectrum and the fact that this also uses POE frees up outlets and reduces wire clutter. I'll be ordering more of these for various other devices behind my TVs. Edit: I've ordered more of these and now all of my Chromecasts are now using these for both power and ethernet. For anyone wondering, the switch they're connected to a US-48-500. The switch shows they're only drawing 2-4 watts each depending on utilization, and they've been very reliable.

I have a Wyze v3 cam. and let's just say things happened to make the wifi stop working so well... Within a few seconds of open the amazon package I was back up and running faster than before! YAY!

Works great as a power adapter when connected to a PoE switch. Will not pass Ethernet no matter how it’s connected/powered. If you only need a way to power your device with PoE this might work OK for you.

Does exactly what it says on the box -- powers and provides a wired connection to a Raspberry Pi Zero.

Product is as described and I would buy again if needed.
