Great video as always. Suggestion: Remind people that the USB Power Switch, many do not have Data Line passthrough. so careful which one you purchase or double check when you get it and send back if data lines are not passed through.
Clicked the video to find out what the pins probing the board were... Staying for the whole video for the algorithm now that I know what I need to search eBay for (I'm in Australia, so Amazon is kinda useless here).
Excellent information!, I have 3 switches where the power source isn't working, but I'm trying to repurpose them by replacing the power source. The chip and relays are in perfect condition; the chip is the PSF-B04. I hope to start my channel by repurposing several switches damaged by the power source and modifying the firmware of the ESP chips. Thanks for the video! 🤖

Friends don't let friends use cloud based smart home devices. So many devices are no longer hackable, which sucks.I still remember using a D1 mini way back in the day to do man in the middle firmware hack. Those were the days.
thank you for your great video i managed to flashed openbeken for 1-gang variant but no luck with 4-gang variant. i used bk7231 gui flash tool and it stucked at getting bus. Do you happen to know what might cause this error ? thank you
Thanks for the info Trav. I gotta say that I am Zigbee hooked here (Probably 50 devices or so). Private,, Solid, reliable, and never an issue so far. but love the ESP stuff 2...
Zigbee is cool for sure especially for the taking out the box and roll but for things like this 4 button switch, I do prefer the WiFi open source there so you can do whatever you want in the firmware. Rocking about 40-50 zigbee devices myself though.
This does not often work. Vendors are now burning programming fuses in the MCU so they are read only and cannot be reprogrammed via the serial interface.
@@digiblurDIY Yeah the controllers are e-waste for me anyways, the sellers didn't tell me the controller couldn't handle the ARGB encoding that my LED strips are using. I was actually trying to find a way to repurpose them.

hello, i try a lot of time with a ZMAI 90 and can't put in reset mode, if you can i will buy 1 for you to try but try from Linux from Windows and nothing, this ZMAI is a problematic switch with monitoring
great video, informative. I have wb3s based fan switch with tuyamcu. not able to get esphome to communicate with tuyamcu. Any thoughts of making openbeken and tuyamcu with esphome video?
I haven't touched openbeken in a while as I decided to go esphome on Beken stuff for now as it also allowed me touch up on my ESP based projects too. I have done the fan controllers with Esphome on Beken devices and it works fine. See here digiblur.com/wiki/devices/other/treatlife_esmlfe_fan_ds03_beken
Yes thank you. I saw this video because you mention it in this video. I was asking for some bdm video for dummies, with examples of how to fix the pens etc… never used this before and i don’t know the potential problems… anything for dummies? 😅
Hi，I bought the same switch as you and finished it according to the video, but the LED won't light up when I press the button. Did I do something wrong?
I didn't change anything, after flashed (bk7231n.uf2) I creat a esphome device and paste yaml(copy form the LTchip tool) on it that's all.@@digiblurDIY
I have the same problem! Same switch. I analyzed the fw dump and copied the code to ESPHome. My configuration is exactly the same as yours. Any idea what it could be?
Windows 10 REALLY doesn’t like ltchiptool… by the way, does anyone know of any videos of installing it (and prereqs) for ubuntu 20.04? Trying to build a flashing machine out of a pi but I’m new to this.
@@digiblurDIY i was actually able to get the previous version working (even tho i still cant seem to flash the CB3S)... windows defender doesn't let me launch the latest version. the issue is mentioned on the github page. thanks for the reply tho!
Hey Digi! Big fan of your videos and work. I cloudcuttered (Cloudcut?) 2 energy monitoring plugs already thanks to you. I'm having an issue with a device. It's a Moes IR/RF wifi receiver/transmitter, similar to the UFO one, but thumb drive form factor. It has a WB3S chip. Cloudcutter couldn't exploit it wirelessly so I opened it up. I soldered all the pins, connected the ame serial to usb you have and when doing the firmware dump, with a few ground to cen touches, ltchiptool begins reading the firmware but then fails after about 2%. Any advice? Thanks so much and looking forward to more vids :)
Not sure if this is what you mean, but I tried checking continuity with a multimeter from the rx/tx to other components and it beeps on a few legs of a nearby chip, also on a bunch of capacitors and even on the data pins of the usb port it uses for power. Do you think I need to de-solder anything?@@digiblurDIY

Great video again. I didn't know it's possible to disassemble pin configuration from original firmware, that's what I was missing all the time
That part is down right amaze balls. Mind is still blown here that you can do that.

I'm not sure it will get much easier after this... maybe just after the 2023.9 ESPHome release is a good time to start.
Great video, I will grab this 4 button for sure! I wish esphome supported Tasmota device groups or a similar feature.
Ask and you shall receive. github.com/Cossid/TasmotaDeviceGroupsForESPHome
Neat little setup! I always screw up flashing lol 😂 😂
If definitely makes it easy to snag a switch in a pinch without soldering.
Thanks Travis.
Man, I would be interested in those WiFi remotes from tuya....
