You can also flash some bulbs and LED strips, using https://github.com/ct-Open-Source/tuya-convert is even easier.
@fedot Ok let me add some explanation here, the pir and door sensors are just 10 seconds connected before they go offline to save battery power, soldering is Needed to keep the esp chip online.

I would just let tasmota handle a timer when the devices comes online… what can you see in mqtt broker?
HI
Its working now , thanks
np, please mark an answer so this topic can be closed.
Hello,
My PIR is now flashed, thanks for the instructions.
I only would like to make a suggestion: I had to compare with other Tywe3s pictures on Google to know which was VCC, GND, IO0 RX and TX on the device to know where to connect on my USB-serial adapter, for me it was not clear on the pictures. Or did I miss something?
There is no “on” stat of the switch. Is it the expected behavior?
Same question for a second switch named “Tasmota2” which make me surprised.
And a last question, I had a long Internet connection break this morning and since it is back, I had a lot of false detections.
Do you see a reason for that?
Thanks again for the instructions and for pointing me… Simply to Google translate 
I always hesitate to use it to be sure not to have problem because of the automatic translation. Even if French the translation is OK.
Very happy to get away from Smart Life app!
Puypo I flashed the same sensor as you with tasmota but I can’t configure it. Could you please share your configuration?
I’m really struggling.
Thanks in advance
Hello @puyoo
Is it possible to have the rules you have on the battery LSC powered sensor ?
Thanks a lot.
