I didn’t succeed in uploading to the one pointed in this topic but I had more luck with the AVATTO S06, also called BAKEEY:
https://1technophile.blogspot.com/2020/07/avatto-s06-ir-gateway-compatible-with.html
who has a TYWE3S microcontroller.
It was easy to flash and has the same LED numbers, they are bigger compared to the round IR gateway. It has the same pinout as the one described by @henning1004 and @depen , thanks for it!
You can find all the instructions for the flash on the blog post.
Thanks for pointing that, it has been corrected.
Yeess 
It’s working! Since I’m a total n00b with platformio, it took me some additional time…
hint to the other n00bs following me,
After: platformio run --target erase
You need to upload the code as well, the –target erase only wipes the settings memory.
After that we need to uploaded executable code 
(I overlooked)
Use: platformio run --target upload
Anyway it’s alive now Thank you… 
Hi there,
Ive got an similair ir-blaster could you explain how to flash tasmota on this unit?
Go to the tasmota webpage. There are how-tos for it.
I finally was able to flash tasmota on it.
Download tasmota-ir.bin from here: https://github.com/arendst/Tasmota-firmware/raw/main/release-firmware/tasmota/tasmota-ir.bin
Download tasmotizer from here: https://github.com/tasmota/tasmotizer/releases/download/v.1.2/tasmotizer-1.2.exe
Follow the instruction on tasmotizer app and you should succeed in installing the firmware.
At first I had a cheap FTDi (pirate from China) and I was not succesfull to flash tasmota with it, but then I purchased this FTDI: https://www.amazon.com/gp/product/B07BBPX8B8/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1
and worked great:
Now I selected on tasmota the YTF IR Bridge module and on the cmd on tasmota I can send and receive commands, i will try to make a more detailed explanation once I set it up on Home Assistant
Let me know if you have any problems along the way and I’ll try to help out! I was lost as you but I kept on reading and found some good answers along the way.
Nice write up, but this all can be found on Tasmota webpage. Nothing fancy here.
Only thing really important is to get a WORKING FTDI adapter. I got a few that don’t work which can cause massive confusion.
Hello, I recently bought an IR-blaster device with a nas-ir02w6 V3 card.
I can see pin hole with TX, RX, CEN, TDO, TDI, TMS, TCK, GND and 3v
Do you know where I could find GIO0 to enable programmation mode ?
Nothing on the underside?
Looking at how TP16 and TP10 is labeled, I guess that is GPIO16 and GPIO10. But not sure…
You could try and trace using this, although TX and RX seem to go to the wrong pins, is it defo an ESP8266 ?
As far as I know this board is not ESPHOME compatible. The main MCU is not a ESP8266 or ESP32 and does not have GPIO0 (this chip uses CEN pin to enable flashing, but not in the same way as ESP chips).
The MCU is a Beken Chip and thre is a project called open beken that has complied a customized tasmota firmware for it.
This firmware can be used on all new tuya chips (beken). I already flashed some cheap relays with power metering, but not any device with rf and IR features, so cant be really helpfull.
I have a device like yours and i’m looking for info to convert it to open beken, if I found some info i’ll share in this post.
Tuya SH4 is a 433MHz module. https://developer.tuya.com/en/docs/iot/sh4-module-datasheet?id=Ka04qyuydvubw
any get a open souce DIY Universal IR Remote Project use esp8266
I ordered this but haven’t received it yet. It works with ESPHome with no firmware flashing. I needed the RF for one device, the IR only version is almost half the price. There is code for it on here somewhere. You need to learn every IR code though but that’s true of any DIY project.

I really wanted to order the below as it works with ZHA out of the box but for some reason they stuck an ESP32 and Tuya chip in it so it works with both. Not sure who that’s for but that required a Tuya RF module along with an RF receiver/transmitter for the ESP32. Not really sure who it’s for but it has a zigbee chip also. Maybe for people with multiple ecosystems like HA and smart life. I just couldn’t justify spending over double for Zigbee, which is all I wantedl that isn’t in the model above.

All the open source ones I found online were essentially just an ESP32 with an IR receiver and transmitter so you would have to design a case to 3D print without everything just being exposed but the code is simple enough to create in ESPHome if you want to go that route.
I really want the remote two by unfolded circle but I can’t justify that price and I’m always skeptical of Kickstarter’s. That thing looks like it was designed for HA with everything else being an afterthought. It does have the potential to be an endgame remote though as the software is open source with a open source API for developers. You just log into HA from the remote and tell it what entities to bring in then map them to any button.
