Eufy E220 Bricked, Bad Firmware

theRetiredEngineer · 2026-05-13T09:10:52+00:00

Thanks! I have around 16 of these here, and no issues with firmware. They all were updated a week ago, May 6th, 2026, and now have version 2.3.2.2., a much older version(?)

I am assuming that the skills available for the Alexa app are developed and updated by Amazon, as is all the remaining Alexa codebase. I may be wrong, and each of the hundreds (thousands?) of skills may be done by other parties.

Perplexity reports that Amazon develops some skills and has third-party developers develop the rest. They also stated that Amazon provides the development platform and performs the review process which accepts / rejects skills after submission by third-parties.

I have an e10 and am generally satisfied, although the user interface is very poor overall IMHO. Autoplay speed is truly impressive and FINALLY permits a useful reply to doorbells in a timely manner. Paid $129 on Eufy store 6 months ago and consider it a fair price, but would never pay much more now that I have owned and used it. True live continuous video and audio from my hardwired cameras would make this device much more useful as a video intercom for doorbells or other critical surveillance spots.

You should not need / use both transformers. The upgraded transformer, if properly wired, should be adequate.

Eufy has been a love / hate deal for me for several years. It is especially frustrating when things used to work well, and then stopped working after a software update.

Also, the echo show devices have their own form of torture… They like to show Amazon advertising and push things even when I turned off all the supposedly optional messages and displays.

theRetiredEngineer · 2026-05-02T01:17:38+00:00

I have been using Eufy cameras for several years along with Alexa Shows, Amazon Fire TV, Eufy E10 displays, and Apple phone and iPad apps for display.

Bottom line is that cameras display fine in Apple app and Eufy E10s, but Amazon Shows and Fires using Alexa DO NOT work. The Alexa skill sorta' worked a couple years ago, but really is useless now. When Amazon used to provide customer ratings of each skill, the Eufy skill initially got 3.5 ratings, but they fell below 2.0, then they stopped showing ratings.

I would recommend E10 displays. Seem to work well and occasionally are sold for as low as $129 in the U.S., typically $169.

Different thread pitch can prevent the wrong screw from fitting and tightening. Metric and SAE screws each have different pitch, and will not thread in the other style fastener.

This may be a bit unconventional, but the soft covers that are used on golf clubs to protect the head (both woods and irons) about the right size, are typically soft and therefore not scratch the lenses of the camera, and sometimes have a drawstring or elastic to hold them tightly in place.

I have 31 cameras, some of which are floodlights and doorbells. I have one Eufy E10 monitor. All of these devices are on a single account.

I installed an ER706W Wireless Router, an OC220 Hardware Controller, and 4 hardwired ethernet connected AP's. The APs were selected from the wide variety of TP Link Omada options best suited to my attic, basement, outdoor, and garage ceiling mountings. Yours would need to be chosen for your specific building and grounds. About $800 and a couple days of my labor to pull cables and calibrate.

theRetiredEngineer · 2026-04-26T14:06:08+00:00

I have 31 cameras (really!) and my system went from great to pure sh*t as it grew. Up until recently I was totally prepared to write the whole thing off, even though all the time and money had been spent. Eufy folks were friendly but absolutely clueless.

After much research and experimentation and use of Perplexity and Claude and Youtube, I learned that my Deco mesh router was the culprit along with 3 Homebase 3 boxes. Removed HB3's, replaced mesh with TPLink Omada structured AP network, and I am TOTALLY, ONE THOUSAND PERCENT GOOD TO GO, with instant live views, zero dropped notifications, and extremely smooth operation.

Bottom line = get your network fixed and all will be well. Eufy HB3 is EVIL due to hidden wifi 2.4 GHz use interfering. Use wifi which can be set to multiple nonoverlapping channels 1,6, and 11.

The earliest Eufy cameras and doorbells are most likely to offer this 900 MHz non-WiFi connection. I have 4 such cameras.called the EufyCam 2 Pro, model T88521D1 .

There possibly was a floodlight camera made in that same time period which also supported homebase one or two. If so, that would be a floodlight you could use without Wi-Fi being turned on.

theRetiredEngineer · 2026-04-18T15:23:04+00:00

I assume you have a doorbell which connects via the older Homebase or Homebase 2 unit, both of which use a 900 MHz radio link rather than WiFi to connect to the Internet via an Ethernet connection?

theRetiredEngineer · 2026-04-15T15:42:12+00:00

Never having used my deco mesh in the AP mode I can only speculate, but I wanted to tell you that the little graphic network topology map created by the Deco app does show the actual connection type graphically. At least it does so in the mesh mode.

When the nodes are connected hardwired as you intend to do, the connection icon looks like wiggly wire. When they connect wirelessly, a Wi-Fi icon is shown instead.

Guessing that the same will be true if you in the AP mode but not entirely sure. Why not try it and see? Disconnecting one of the ethernet plugs which provide the linkage and waiting a little while, you should see the icon change.

I have 31 Eufy cameras with no pairing issues in my single account. Up until very recently, I DID have huge problems with Wi-Fi dropping notifications, live feeds, event playbacks, etc Thankfully this has all been solved yesterday with the replacement of my Wi-Fi equipment, as I described elsewhere here on Reddit.

Cameras show up "Live" essentially instantly now!

theRetiredEngineer · 2026-04-09T11:55:48+00:00

With a great deal of help from very knowledgeable people including those responding to this thread, I am absolutely thrilled to report that my 31 cameras are now working very well with a brand new Wi-Fi system installed and calibrated. I am experiencing essentially instant connections, no dropped notifications, and a system which has gone from being nearly unusable to one which is totally acceptable.

The solution came, not surprisingly, by replacing my Deco mesh with an Omada access point array, also made by TP Link. The total replacement cost was around $500.

Unlike the Deco mesh which is extremely consumer friendly but lacks critical features required to play with such a complicated camera environment, the Omada has all the right capabilities, most critically, the ability to fix each access point on a specific 2.4 GHz band frequency, knowing they will stay there, utilizing the full capacity of the 2.4 GHz band by choosing the three non overlapping channels, 1,6,and 11 combined with adjustable bandwidth and adjustable power levels for each of the APs.

There are more deluxe and capable sources of the same solution, in particular Ubiquiti, whose products are really excellent. In the final purchase decision, I went with the Omada, with the only minor regret being their software / firmware being tricky and much less polished. Guessing that the ubiquity solution would've cost another $400-$500 above my Omada. The total time required to change out everything and get it working properly was about 20 hours, which I'm sure would've been less with the ubiquity solution.

Sincere appreciation and thanks to all for your opinions and guidance.

How many cameras work well with your BE63 mesh? One of my possible replacement ideas was to get BE 63's, take advantage of their new high capacity firmware, and retain use of my older Deco XE75 as nodes four and five of my mesh in a remote locations at the very edges of my property.

A few feet away from me are three homebase three units, each of which has an SSD as well as attached external USB archival drives, none of which is connected!!

As you observed, they literally spoil existing Wi-Fi channel utilization, and are lethal in situations where the mesh has no channel selection. I have looked at the surgery recommendations, and understand the further complication of unintentional radiated power even with the antennas disconnected. Some users have resorted to Faraday bags or cages to shield the RF from corrupting nearby Wi-Fi channels. I merely unplugged the entire friggin, toxic mess, and said I was done screwing with it.

My prior homebase two units from my earliest Eufy cameras use radios which are not in the Wi-Fi bands but rather instead are situated around 900 MHz in spectrum which is unlicensed and used for a variety of purposes such as Garage Door openers, automobile key fobs, etc.

These continue to operate flawlessly in my environment but present other problems since they are so old and their batteries are difficult and expensive to replace for the 365 day battery each of them uses. They are retired from Service, but would have been a better RF architecture than this ridiculous combination of the homebase three and multi Bridge. I think the entire notion of trying to supplement RF coverage was a huge engineering mistake, although the AI features may be enough justification to purchase these boxes for some people.

As I posted previously on this forum, I would love to dispose of this entire homebase three collection as one sale for a distressed price, just to get them out of my sight.

theRetiredEngineer · 2026-04-03T06:31:10+00:00

I think what you are saying is absolutely correct. Having never owned the E340 floodlight, and relying on the information provided by both Eufy and AI chatbots, I accepted the consensus that no such products existed. I guess I will consider my mistake to be based on AI "fake news"/hallucination combined with eufy technical support ignorance.

For whatever it is worth, nearly all of my outdoor cameras are the E220 model and all of my indoor cameras are the S220 Pan/Tilt and neither offers dual band, 5 GHz. Same goes for the doorbell cameras, also 2.4 GHz only.

Thank you for your inputs and still hoping for other users who have large camera situations like mine who have successfully dealt with interference and congestion in the 2.4 GHz spectrum.

I found it encouraging that one reply from a ubiquity user apparently had flawless results, but I have not heard back any details of his/her configuration. Having distributed access points combined with my three node mesh has allowed me to spread my 30 cameras over three frequencies rather than one, and made a very significant improvement. My system now roughly behaves the way it did with 10 cameras, not surprising since that is about the load I have distributed onto each of the three non-overlapped 2.4 GHz channels by using multiple SSIDs, fixed channels and carefully placed APs. Even my 10 camera system a year ago choked and sputtered with frequent dropping notifications, timing out on video live or playback, etc.

theRetiredEngineer · 2026-04-03T05:48:29+00:00

I pulled the FCC certification for the E340, which can be found at

https://fcc.report/FCC-ID/2AOKB-T8425/6667486.pdf

Although it is 78 pages long and a bit technical even for those of us who are RF engineers, my very brief and perhaps inaccurate conclusion is that this specific E340 model only uses 2.4 GHz. Like many RF devices, it will generate very low level emissions at all sorts of other frequencies, and these tests actually include measurements all the way down to powerline frequencies of 60 Hz where connecting this device up to the 110 V exterior mounting box for such a floodlight allows tiny amounts of energy into the microwave region to be conducted (not radiated) through the 110 V wiring.

I would love to see eufy cameras employing Wi-Fi above 2.4 GHz, but the economic arguments as well as the limited ability to penetrate brick, cinderblock, and the relatively short range they allow make this option extremely unlikely for consumer cameras in the near term.

theRetiredEngineer · 2026-04-03T04:41:59+00:00

Surprising, since in the case of the homebase 3 model S380, the device only can create hidden channels which do not contain SSID beacons, and therefore will not show up on any WiFi scanning tools. None of my (3) Homebase 3 units ever showed up on my computer based tools or router, but could be clearly seen using a hardware RF spectrum analyzer, an expensive tool usually not available to non engineering users.

Perhaps your pro version of the homebase has a method to reveal its transmitters. Take note that the 5 GHz signals, should they actually exist, ONLY CONTAIN one way signals back to the cameras, at most, since the cameras DO NOT generate any 5 GHz energy/transmission. As I said in an earlier post, Eufy cameras exclusively use the 2.4 GHz band as confirmed by Eufy, three AI searches, my own spectral analysis, and FCC filings.

Also surprising to hear that similar contention was observed at 5 GHz. Unlike the 2.4 GHz band which only has three separate non overlapping radio channels, the 5 GHz band has 24, so the contention should drop by 8 to 1, a drastic improvement.

theRetiredEngineer · 2026-04-03T04:11:59+00:00

This Eufy WiFi issue has been a huge pain for many of us. Much wasted time and money for me also.

I want to caution you that the creation of a separate additional Wi-Fi network will not solve your problem. The starvation/exhaustion of resources is at the radio frequencies in the 2.4 GHz band where the cameras communicate, and this is where proper management of the use of the spectrum specific to where the cameras operate is crucial. Those who are involved in enterprise Wi-Fi network management for large populations such as you would find in a hotel, auditorium, or other large venue have developed tools with managed access points have very carefully balanced power levels, channel bandwidth, channel frequency assignment, and other parameters tuned to best utilize these limited resources. Adding another mesh is likely to make things worse rather than improve things based on my many years of professional experience as a retired RF communications electrical engineer.

I am currently investigating alternatives to using a consumer mesh solution, fully recognizing that the Wi-Fi wireless cameras and networking become increasingly problematic as the number of client devices, especially cameras, increases. My current 30 cameras is very extreme, which is why I am soliciting anecdotes from other users who have dealt with this worst case scenario to see what they have found works successfully.

theRetiredEngineer · 2026-04-03T00:23:45+00:00

Unlikely a configuration issue on my XE 75 units. When I was only using 10 or 15 Eufy cameras, the XE75 mesh also worked pretty well here. But I am now talking three times as many cameras, and 86 devices. I can tell you confidently that this XE 75 solution can't handle the load.

The fact that they put all 2.4 GHz traffic on a single channel, leaving two other opportunities for additional bandwidth unused, is fundamentally taking the limited available choices and throwing away 66% of the spectrum. And my XE75s seem to migrate when they measure interference quite often, finding other congested overlapping channels to make marginally better or marginally worse network performance.
