- Опубліковано 3 чер 2019
- Another esp8266 based Wifi smarthome outlet sold by Teckin. This model also uses the SmartLife ap. I had picked up a power strip made by Teckin and figured I would try the outlets as well. I liked how they were smaller than the other wifi outlets. I the few weeks since I recorded this video, they have continued to work fine. I did put tape over the led
If you want one, here is a non-affiliate link but it is through Amazon smile which I do recommend using since it cost's us nothing extra.

Nice review.
As a part-time electronics designer, I appreciate the teardown and your comments are relevant. I did suspect that they would use ESP8266, now I'm thinking about writing custom firmware and how to flash it in. I already ordered a similar one with "Power monitoring" feature, that could be a little more complicated.
Thank you Vasily! I have an older Etekcity plug that has power monitoring. Its an older vid ua-cam.com/video/5UTWIupIKkk/v-deo.html
Thank you to helping me figured out what's the problem i had with my device. i Just subscribed!
Thank you so much!
nice teardown, thanks!
I put to many amps on one of mine & the fuse is likely blown.
Not worth replacing the fuse, i'll likely buy a few more, but good to see the insides without having to teardown myself
Me too. Too bad we don't have a spare box of fuses, eh? Looks like it might be a manageable repair for a novice with a soldering iron.
Annnd, I pulled the fuse and twisted the leads together. Yup. I can confirm it was a blown fuse. The unit works now! Proooooobably not the safest thing at this point. :D
@fixitfrank, great video! I had a question about the certifications. the plug says it "conforms to UL std 60730-1". however, no UL logo appears on the plug. does this mean that the plug is not UL certified?
Do you know what the little modules are called where the plug fits?
Could you identify the markings on the power supply control chip in one of these?
Thanks dude for sharing that
No problem 👍
where is smps transformer ?
Thanks for the teardown video. Have a question, I see the soldered terminal for the ground outlet, but have you ever checked for continuity between the ground pin to ground terminal? I picked up two Energizer brand smartplugs model SA-P202 that look awfully similar to the one in your teardown and found that although it has a ground pin and appears to have a soldered down ground terminal, there is no continuity between them! I find this disconcerting!
Good question. I didn't recall so I just checked and yes these have the ground connected. It just passed through so the internal circuit is not grounded but the device you plug in is grounded.
I appreciate your efforts and no doubt it's a good video. As a suggestion, you should try to reverse engineer the product probably with rough schematic. It could be helpful for beginners understanding electronic section of product
I fully agree with you. A schematic would be very helpful. I had done another version of this where I tried to do a schematic. However truth be told, my handwriting and drawing skills are quite poor. Next time I will try and use a Paint program and show the schematic that way. I like it when people suggest these ideas so I truly appreciate it.
Nice video!! There is some wind or ac unit being picked up by your mic. Any chance of fixing that?
I hear you. Not in that video unfortunately. It was a heatwave that weekend so I did have a fan That will help for sure when I get one. But I don't have a way to filter it out. I don't have fancy editing software unfortunately. I may remake this vid at some point and regardless I am working on improving the audio. Hoping to buy a decent lapel mic soon once I save up a little more. Thanks for watching and sorry about the fan rumble.
I was trying to connect one of these and as soon as it connects it starts to go on and off continuously and never stops. Any idea what might be wrong? It's a WAGA WiFi outlet. Do you know how to factory reset WAGA?
Either the power button faulty or the relay. I would suggest to press and release power button multiple times with little amount of force to troubleshoot.
Do you know what the power draw is on one of these plugs while idle?
I don't but it can't be much. I messed up my killawatt playing with the hidden menu and now it's out of calibration. Sorry.
i have a Geeni smart plug that looks identical to the one in this video. i personally would have loved it if the LED was in front so that i can actually see it's in pairing mode without having to go around to the side. With the LED on the side i found it was very difficult and time consuming because i couldn't just see what was going on. other than that i don't blame you for wanting the LED on the side.
I wish I knew why companies use these super bright indicators. Something small and more dim would be preferred in my opinion. Or they have a way to cover it or disable it in the software. My Wyze cams can have their LED's disabled so I'd think other brands of outlets should be able to disable their LEDS in my opinion.
Put a mirror on the side of it when parring.
Ok, so I connected this to an AC (I know I know) and now it doesn't work (which is what lead me to this video).
Which of those 2 fuses do you think I should replace? Thank you in advance.
Probably the smaller one that goes to the low voltage PSU. It's a 10ohm resistor if I recall correctly. Flameproof type. That should cram all the smoke back inside ;)
Thanks, figured out it was under that orange rectangle box. T10 250V
Now to find a place that sells a single one.
Thanks again 👍
@@sergioa.6657 That fuse protects the load on the relay. You may want to check it, but unless you had something plugged in, its probably fine.
My 10a 250v fuse blew under to much load now I cant find one anywhere. Does anyone know where you can find one?
Is it possible to switch these into a "inching mode" for operation?
I don't think so. Not with the firmware I had at least and not as of yet. I have seen that with Sonof if I recall correctly and Etekcity(I think). You might be able to modify the Tuya firmware though if you are inclined. It's a bit out of my wheelhouse but I'm sure it's possible.
Thank you for this video. I am having a problem with two of my Teckin plugs so I though I can fix them. One is not switching on so I suspect its the fuse and the other keeps switching on and off so I expect its the relay. I will do some testing to double check the issue. Do you know what are the names of the two fuses used? I want to order a replacement. Thank you.
One is a 10 amp. Thats probably the issue if the relay is clicking and nothing happens. If you can see the outlets on your ap, then the low voltage circuit is working and the high voltage(to the relay) is the problem. If its totally dead, I'd still suspect that 10amp fuse over the low voltage fuse. If the low voltage fuse is bad, that means something in the radio/wifi section failed and that is pretty much time for the trash(or toss into a drawer for spare parts).
I've had 3 in service for more than four months. All just switching 13 Watt LED bulbs. One switch just did a buzz-pop and the relay dropped out. Reset the unit but Smart Life can't detect it. Have a spare unit that works on the same lamp. Wondering about the long-time reliability.
For what its worth, I have been running these for over a year without issue. The only ones I had problems with were Wyze brand. The Teckin have been running great. I bet you lost a fuse on the popped one if you have no leds flashing. If you do, my suspicion would be a manufacturing defect. I would not worry about the longevity too much. These are built pretty well. I have another brand(the same thing inside) that I've been running for over 2 years without issue. These seem to be pretty reliable aside from the one-off problems. I like them a LOT more than the smarthings zigbee stuff.
@@FixitFrank No fuse blow 3.3 V regulator is still working and LED does fast or slow blink. I am thinking the Wi-Fi module is fried or the relay driver blown.
The relay transistor would make sense. If its blinking that is a great sign. You might want to see if you can talk to it via the flash pins with something like Tuya convert. The wifi module is probably OK though since its controls the blinking.
Is there any unique IMEI code to identify individual smart switch?
IMEI codes are for cellular devices as far as I know. These use MAC Addresses like other wifi devices.
I have 4 of the same outlets. Trying to update firmware on each and receive error stating the update failed-try to move outlets closer to router and try again. All 4 outlets are within 5 feet of router. Any ideas? The new firmware is V1.0.4. Supposed to correct timing issues. Any help is appreciated.
I do. Dump the Teckin app. I run all of mine through the SmartLife app. Smartlife is just a prettier version of Tuya's app. Teckin, Nooie, GoSund and others just use the generic Tuya firmware with their own apps. Smartlife seems to work the best and then I can use one app for all of the outlets I have. It allows firmware updates directly from Tuya(The actual maker of the software).
If you want to keep the Teckin app, try un-pairing and re-pairing. Also try rebooting your router. Moving them probably isn't going to help. I have heard that having your phone in airplane mode with wifi only enabled can help too, but I have not tried that myself.
@@FixitFrank Thank you very much for your response. I am using the smart life app. Sorry, I should have specified that.
@@cutum Really and you are still having issues? Very weird. In that case, I would try:
1. reboot your router.
2. un-pair/reset each module and try again.
3. If you have a firewall, turn it off for the update and then back on.
4. Remove and re-install Smartlife.
I updated the firmware in mine not too long ago without issues. I wonder if maybe its the time of year? Maybe wait and try again? I'm sorry I don't have more insight.
So it is a esp82XX device. Then how come tuya-convert gives me error "WARNING: it appears this device does not use an ESP82xx and therefore cannot install ESP based firmware"
That is strange. I have used Tasmota on them successfully. I would think Tuya convert would work too. I dont have one open at the moment but if I get time I will see.
@@FixitFrank I bought a 2 pack of these just last week. They came with a Realtek chip in them. Sadly, I didn't discover this until after I broke them open, so I couldn't return them.
4:57 "...thermally welded..."
Have you tried heating it up for easy teardown?
I didn't because I am not able to only heat the sealed area. I tried with a hot air reflow tool but it just melts the entire area around the seam. There's no reasonable way to heat just the weld points. I'm also not 100% sure it wasn't high frequency welded. You get similar results. I'm happy with how this went for my purpose. Not the cleanest opening but nothing was damaged.
I got the same result: the seal isnt giving way through heat.
I thought about a dremel but going around and prying just ended up working. Believe it or not, I'm still using that outlet from the video. The back is a little chewy looking but its solid.
@@FixitFrank I used the can opener tool on my pocket knife, aided by a flathead screwdriver a bit thicker than the ones you were using; too thick to puncture, but just right for prying once an opening was made. Great visual tutorial on cracking into this thing!
