Problem with neo coolcam 16A nas-wr01w power plug

[tty74it]

I've buyed 2 of this power plug. One is flashed without problem. With the second one i can't flash it, and it reboot many time when tuya-convert is activated

smarthack-mqtt.log smarthack-psk.log smarthack-udp.log smarthack-web.log smarthack-wifi.log

Thank's

[kueblc]

Did you buy these two plugs at the same time?

Would you share the logs and firmware backup from the other device?

[tty74it]

Yes same time device-info.txt smarthack-mqtt.log smarthack-psk.log smarthack-udp.log smarthack-web.log smarthack-wifi.log

[kueblc]

Can you post the backup as well?

[tty74it]

Yes in the zip

Thank's

[kueblc]

I do not see the registration call in your web log. Have you tried putting the device back in pairing mode and starting from scratch?

Is this a clean tuya-convert install or have you added or changed any files?

[tty74it]

Now i've tried win a cleaninstall and any files are changed (only config wlan interface name WLAN=wlx00156d846131)

But is the same, i see the device reboot many time and also the relay status ( click sound on reboot i think) smarthack-mqtt.log smarthack-psk.log smarthack-udp.log smarthack-web.log smarthack-wifi.log

[kueblc]

I see that these two devices are running different firmware, and that the first device was converted in April. It may be that you have gotten a firmware update from Tuya since then, blocking tuya-convert.

[tty74it]

Ok thank's , i'm waiting a new version tuya-convert, because i see is not to simple solder wire in this device. At the moment i use the first device converted

Many thank's

Hello, any news? I'm with the same problem, new firmware from Tuya.

[KoalaBear84]

I have 5 of these now, the first 3 flashed without problems. Ordered 1 on july 5, ordered 2 on july 25.

The last 2, ordered only 4 days later they do flash, but they do NOT connect to WiFi. They appear bricked, but when you remove the wifi (disconnected the modem/router) they do supply tasmota-xxxx, and supply the wifi (again), but they just won't connect to the wifi. The credentials are 100% correct.

They don't listen to anything, the button does not turn the relay, which I understand, because it doesn't have the template. It doesn't respond to 4 short button presses for wifi reconfigure option. It doesn't respond to keep it pressed for 5 seconds (or 40). It doesn't respond to power cycling. Really strange.

[KoalaBear84]

Sorry, for me it is resolved., I took it to a friend to escape my WiFi, added it to his network and saw that the new one has a completely different MAC address range (vendor). The previous ones were all 80:7D:3A, and the new ones are D8:BF:C0 🙊

I really scanned the network 10 times, and none of the MAC addresses reported "Espressif Inc.".

[stefxx]

I just ordered 5 of those plugs. I was only able to tuya-convert 2 of them successfully. I will have to wait for my serial adapter before I can attempt serial flashing the other three.

Too bad. OTA flashing is sooooo much easier. Really hope a future version will fix this.

Hi. Do you get any information how to open the plug with latest one? It seems like there are some differences between previous model. The new one is really hard to get into under the PCB which is pad for flashing.

[stefxx]

Nope, haven't tried yet.

[worldwidefelix]

Nope, haven't tried yet.

I see. Hope to share how to work out this matter altogether. Thx

[stefxx]

Just opened the top cover. I was hoping it would be simple but I can't find any screws to get it out of it's housing.

Might need to sacrifice one to see how we can open them neatly.

[KoalaBear84]

I do not have experience with it, but found this last week, it has some info about it: https://github.com/xoseperez/espurna/wiki/Hardware-NEO-COOLCAM-NAS-WR01W

[stefxx]

I've seen that as well. But it is not the same version (10A vs 16A version). It can't locate the two screws to get the boards out of the housing.

[stefxx]

Turns out there is only the one screw. Hammer carefully on the pins and the whole module will come out. Watch out for the earth connector (at the screw point), thats all. Unfortunately, I am afraid I already ruined it, but that's ok.

Here are some pictures:

You can clearly see my damage on the second picture, the black part is broken. Anyway, I was able to find GND, 3V3, RXD and TXD (TXD is accessible but the label is hard to see below the relay. I can't find GPI00, I am afraid we need to take it apart to get to it.

Thank you for sharing your experience. Mine was already got damaged either while I tried to open. I had no idea after opening top cover at that time.

At the first, I was looking for another 2 screws. Now, I know how to disassembly finally.

[sanderlv]

Any luck or any schema available to do the flashing?

I have the same issue. I have tried to flash but get below. I am not a linux expert and have tried for a few hours how to get the 5 logfiles from my pi to windows... installing samba, editing files, etc. etc. but no luck... so I do not know how to help with sending my logfiles to you.

1. Connect any other device (a smartphone or something) to the WIFI vtrust-flash
   This step is IMPORTANT otherwise the smartconfig may not work!
2. Put your IoT device in autoconfig/smartconfig/pairing mode (LED will blink fast). This is usually done by pressing and holding the primary button of the device
   Make sure nothing else is plugged into your IoT device while attempting to flash.

Do you want to try flashing another device? [y/N]

Something is happening on the plug though because the red light flashing stops after the first attempt...

[djfanatix]

I have the same issue, bought 3 plugs, 2 worked fine, but the 3rd switches of the pairing mode and the relay flickers when Tuya convert tries to connect.

[sanderlv]

Just asking... any update on this device? I have successfully flashed 16 other devices now running esphome :-)... Wanting to use these 2 as well...

[stefxx]

Nope. We have to wait until tuya-convert works again on newer devices (if ever). I tried to open one and in order to flash them serial I most certainly destroy them in the process, so I decided to wait. Again, it might be a looooong wait.

[sanderlv]

Argh... I hate to wait (long), I tend to forget then :-)

[bobybobybob]

it is less difficult to solder the Flash component. Then solder on the circuit board of an ESP01, put Tasmota on it, unsolder it and put it back into the china socket.

[stefxx]

Hi @bobybobybob ! Do you have some instructions/pictures on how you flashed the Neo Coolcam?

[bobybobybob]

I have two of these adapters. One broke when I took it apart. From this broken one I unsoldered the flash module. From one ESP01 the flash component was desoldered and the other one was soldered. With Tasmotizer the Tasmota is loaded. Desoldered the component again.

With the other adapter with a side cutter I removed the flash component and soldered the rest. Soldered the Tasmota Flash module into the adapter and finished. Set the Tasmota Template etc. and everything is great.

[stefxx]

Thanks @bobybobybob , also for the great pictures. Not sure if I am brave enough to do that, but then again, I broke one already and the others are currently unused because I can't flash them... And if not, I am sure it will help others!

[Gunner251192]

Hi, when running Tuya convert it seems to regocnize the plug, because it stops blinking fast or you hear the relay clicking. I got 10! of them ( NAS-WR01W 16A plugs bought 3 weeks ago) and really want them to flash so i can use them local in my automations. It would be really great to get this fixed, to help i uploaded my logs when running Tuya Convert, if there is someone who can point me in the right direction it would be really great. They are pretty useless now.

Thanks in advance. https://github.com/ct-Open-Source/tuya-convert/files/5575765/NAS-WR01W.zip

[Shamshala]

@stefxx ... I can't find GPI00, I am afraid we need to take it apart to get to it.

If you haven't already found out, you don't need to look anywhere for GPIO0 actually, it's connected to the button. I'm kinda impressed that you were able to hammer it out. I took the harder way to desolder the top PCB inside the housing in my 6 plugs. :rofl:

I tried TuyaConvert two times, it bricked my sockets everytime but i already knew how took them apart so it wasn't a big deal and flashed them directly.

[clausmuus]

Thank you all for your documentation. So it was possible for me to flash my devices successful. For the second one I need only a view minutes :)

[gabest11]

I have one with ID: 02... that do not work with tuya-convert. Desoldered the flash chip and saved the original fw if anyone needs it. Can I just load it with files/tasmota.bin even though it's less then 0.5 MB and the original is 1 MB?

[clau-bucur]

Thank you all for your documentation. So it was possible for me to flash my devices successful. For the second one I need only a view minutes :)

I've just flashed tasmota-minimal.bin using Tasmotizer. It creates the wifi, I can connect to it, I get ping replies from 192.168.4.1 but I can't connect to it to configure it. No ports are opened (even after a couple of hard resets).

Can you describe your flashing procedure? What tools and what firmware have you used ? Thanks!

[clau-bucur]

Nevermind, it works now :) I gave it another shot and flashed by selecting image "Release / tasmota.bin" and checking "Erase before flashing".

[finalstate]

Don't use a hammer to open the plug :-) After unscrewing and taking the 'female' side off:

• either use a vise: put the plug into it, and slowly close it. Two thirds of the plug pins length pushed in should be enough to get it out by hand
• even simpler, if you have a drill press, use it to push the innards out. Be careful not to damage the bit holder.

[alnavasa]

I have flashed It soldering the pins but I might have damaged the step-down voltage converter, Or I don't know what, but, I have two flashed ones with erratic behavior: 1: I plug it, it works ok, I un-plug it, and plug it back, nothing happens, doesn't work. un-plug it, wait 10 min, plug it back, it now does work.

2: Plug it, works for 15 seconds, then it powers of.

In My case is a "Avatto 16A Power Monitoring Plug" from aliexpress. but its the same probably

I am wondering if I broke the step-down converter, or what the hell happened...

[ragzol]

I have flashed! It soldering the pins tx, rx, gnd, 3.3V pcb and connect serial usb adapter. flashing: Connect pin to usb adapter: tx->rx, rx->tx, 3.3v -> 3.3v, gnd-> gnd GI00 -> gnd switch push or connect two switch pins

Flashed, no soldering. It takes a few attempts to get the pins just right ;)

Where did you get that smart clamp from?

[pesor]

@stefxx

Thanks, it is ordered. Got 6 Avatto 16 Amp, all with new firmware, so this is a really nice solution without soldering, and I gladly wait for delivery.

When I look at your picture, what did you do with the GI00, it is not clear from your photo.

[stefxx]

Just press the button during startup.

Let us know how it goes, I don't know What I did to my Avatto, but they booted and after a minute or so died. Tasmota was working on them, but after the minute they where gone... I got tired of trying to flash and reflash them

what size did you order?

[stefxx]

I have it for a while, I think I got the largest one. But if it is just for flashing the Neo Coolcam, it's larger than necessary.

[pesor]

12 pins double row, 24 pins in total, that is the same size as @stefxx

I ordered 2 PCS of theese. And through some very informative posts here I've flashed tasmota on them. They state that it should be power monitoring on theese ones but I'm guessing that's not true? Does anyone know?

That is true, they have Power Monitoring. I would like to order some more, but I don't dare as I don't want to open them and flash them through hardware.. :(
