Update on Tuya Devices (tuya-convert)

Hardware
1

let me preface by saying that I’ve flashed about 8 Tuya based devices with the tuya-convert without issue. So this week when they were on a flash sale I quickly jumped on it.

It seems they’ve got smart and caught on to what the community is doing and it looks like tuya convert isn’t working anymore… So I had to revert back to the old solder and flash method.

Just an FYI for anyone adding these to your home.

If you updated your tuya lights firmware, you are fried.

Huh? I don’t understand what you mean

I’m not using tuya firmwares though. I don’t even use the Tuya app(s). I’m flashing third party FW on them.

Its not just an update, they’re being shipped with newer firmwares.

Hi,

can anyone post a link to flashable power plugs? Or by now is just pure luck?

Alternatively power plugs that can be open easily (possibly just a screw driver) , and that pins are easily found/connectable

I ordered some of these on 21st and again 29th May and they flashed with no problems. I flashed them straight out the box.

Proceed with caution!

I bought the Teckin square plugs from Amazon UK 2 weeks back. I flashed them straight from the box over the weekend with no issues.

However I’ve no idea if I got lucky and received some older stock…

Thanks a lot. Currently looking for EU plug version

10

Any luck finding “still flashable” EU devices? I am currently in the same boat :slight_smile:

11

haven’t had the courage to order …

I ordered two sets of plugs from the same supplier within 1 week; first set wash flashable, second set not :frowning: now trying to crack the cases open to flash the open firmware…

13

Which one did you buy? I am currently deciding which one to buy that should be fairly easy to open up and solder.

14

I bought this one: https://www.amazon.de/dp/B07D5V139R/ref=pe_3044161_185740101_TE_item

I haven’t opened any of them yet but heard that using a rubber hammer is the best way in doing so (simply hammer the sides a few times until the inside falls out)

15

I finally found a bit of time to open my Teckin SP22’s and used the hammer approach. To be honest; I initially didn’t believe it would be so incredibly easy to open them by using a hammer! I didn’t have a rubber hammer with me, so just used a steel one and hit the sides of the Teckins a few times. After a few blows you will see the back of the plug coming out of its casing without any damage.

Now I just need to solder and upload the esphome firmware

16

Blitzwolf bw-shp6 are great! Feels like good quality, small and easy to open up with one screw.
I soldered some pogo pins on a pcb experimental board and used that for the initial flash since I did not want to solder the test points.
I have four of them and so far they are working great. Plan to buy more of them soon.

In UK stock:

is there any documentation for converting these tuya converted plugs to ESP home firmware? Is it just a case of downloading and flashing a new .bin?

Any links would be appreciated - I find the ESP home site very confusing.

I used this, but the GPIO values for my UK sockets were slightly different. Only took a short while to work the right ones out though.

which sockets do you have? Mine are Teckin SP27
