Did you follow a process similar to this - https://github.com/arendst/Sonoff-Tasmota/wiki/Configuration-Procedure-for-New-Devices?

Question - where you able to flash this OTA or did you have to open it use a serial adapter? Does this device go to sleep after inactivity or with the magnet present?

Hi Meingraham,

I flashed with serial adapter using the latest Tasmota firmware.

No I didn’t follow the process!

And yes I can confirm that the device is going to sleep mode after the magnetic switch goes on/off.

Yes, the latest TASMOTA, but by which method - hooking up wires or wirelessly using Tuya-convert?

See if that configuration process works for you to find the GPIO configuration for the device.

Soldering the RS232 USB adapter and flashing directly.

Thanks for adding the photo's! I ordered a few of these also (have not received them yet). I was hoping they used the tywe3s board since the description listed "Tuya App" etc. I see from your photo's they also appear to have broken out the pins needed to flash firmware (as you have already done).

This will be my first adventure into Tasmota and I am hoping to use the "Tuya-Convert" method. If that doesn't work I will do as you did and use a serial to USB. One question (for anyone who knows). I see the Ground (G) and power (V) are marked. The other two are listed as N and S. Do you know which is Transmit and which is Receive? I'm new to this and wasn't sure (I'm guessing they are marked from another language?).

Thanks!

EDIT: Fixed "OTA" method to "Tuya-Convert" to be clear as to what I hope to do.

Hi cbmboy,

Please wire your RS232 to USB as per picture below!
img_3884

Then use the https://github.com/nodemcu/nodemcu-flasher/tree/master/Win64/Release application to flash the device with the latest Tasmota Firmware using the following config:

Baudrate 115200, Flash size 1 MByte, Flash speed 40 MHz , SPI Mode DOUT

You need to connect GPIO 0 and GROUND while connecting the board to USB.

Good luck.

@senadaruc
Did you try using the four breakout pin holes to see if they are the Tx, Rx, Group, and Vcc?
I anticipated that this was the case - but since I am inexperienced, I could be wrong.
Also, it appears there is a button on the front, and from the pictures you attached, I see it is marked (SM1).
Were you able to identify what this is wired to?
Again, I was thinking this may be GPIO 0 to Ground as many other devices do.
This would greatly reduce the skill (soldering) needed to accomplish the Tasmota conversion.

This would make the process much easier if these assumptions are correct.

Thanks!

@senadaruc There has to be a extra electronic which sends ESP to off.
Because Tasmota doesnt support deep sleep. Could you post a picture of the other side of the PCB
I am interested how is this be done.
Thx!

cbmboy, the button will not put the CPU to program mode so I soldered the GPIO 0 and used the ground to force the program mode.

No label on the interesting IC U1 :-(
It looks like it does have a step up power converter so the 2 AAA cells are no problem for providing correct voltage for the ESP

Mhh, you could try to measure via a DMM the different GPIOs if one goes in high state when magnetic switch is triggered.

Another question is has it a different behaviour for open and close?
So maybe you get just the information you can use device was "up"

There should be at least two correct? (Asking as I am still new and trying to learn)
One for the magnetic switch, and another for the LED?
Would there need to be a third also for the button (don't know what this does yet).

Ok so I triggered the magnetic switch and tried to see which GPIO is giving me continuity connection between GND and GPIO output but unfortunately, none of them is closing the circuit!

@Jason2866

The magnetic switch does not trigger a Gpio from the ESP chip
The U1 is a MCU. This chip reacts on the magnetic switch and enables the ESP chip.
The ESP sends with orig. firmware just a message via wifi when activated...

Aha ok so now I managed to get some ON/OFF messages at the Tasmota console using the Manzoku Strip Module but is not ideal since the default config is switch but I need a sensor, any help bout this?

@senadaruc Tasmota uses NO Deep Sleep, it is not possible/wanted by design. This means CPU is always on. See https://github.com/arendst/Sonoff-Tasmota/wiki/energy-saving

Tasmota is not intended or designed to use with battery powered devices

@Jason2866

@cbmboy You get a Info from device (via mqtt) that it is (or was) online. This info can be used in your Home Automation solution.
With Tasmota on this device you cant expect more, because ESP chip (where Tasmota is installed) is not powered most of the time...

@Audiothor

Ok thanks @blakadder, so now, the LSC Door sensor is flashed with the last Tasmota version v8.1.0 Doris (only hard method works)
@blakadder : Impossible to use the definition template you shared because it's not the same hardware.

I tried to apply this config :

module 54
backlog TuyaMcu 11,1; TuyaMcu 51,51; TuyaMcu 12,3
rule1 ON Wifi#Connected DO backlog serialsend5 55 AA 00 01 00 00 00; delay 10; serialsend5 55 AA 00 02 00 01 04 06; delay 3; serialsend5 55 AA 00 05 00 01 00 05; ENDON
rule2 ON TuyaReceived#Data=55aa000200000155aa0005000501010001010d DO POWER ON ENDON
rule3 ON TuyaReceived#Data=55aa000200000155aa0005000501010001000c DO POWER OFF ENDON
restart 1

But I still have the issue with MQTT : only "Off" and never changes to "On"...
Is someone have an idea ?

The tuya received string has two serial messages in it, something is wrong there

@Audiothor

@blakadder
Hope it will be my last question ;)
So finaly I bought the exact same model (Earykong TYMC-1 Door Window Sensor) as your description link there : here
I apply the exact configuration like you recommandation in Tasmota 8.1.0.
POWER ON and OFF are working fine ( yes !) BUT I can't catch the mqtt message because MQTT has not enought time given by the door sensor.
Manualy it works because I prevent the device from going to sleep by actuating the reed switch constantly (approximately every 5 seconds). And I use temprary the SerialSend5 55AA000200010002 command...
But after impossible to catch any message...
Hope my question not so stupid :) Thanks a lot

nothing you can do here, its how the sensor is designed and it depends on how long you need to connect to wifi and your broker

Hi all. Thanks for all the information that you gave in this thread. I did the flash *using the 4 pin available (inverting tx/rx as they are connected to the esp). I have the tasmota loaded and it works. My problem is that I cannot see the switch On/off but only this message is received in the console when I shift the magnetic sensor:

0:00:05 TYA: Send "55aa000200010305"
00:00:05 RSL: tele/tasmota/RESULT = {"TuyaReceived":{"Data":"55AA0002000001","Cmnd":2}}

I tried to increase log to level 4 in tasmota to understand which are the dpID but no success. anything is shown in the log. can you point me in the right direction? Danilo
Thanks

Hello all, I got myself this device and try to flash to tasmota-bin (v8.2) with esptool.py (v2.8)
I used the info from https://templates.blakadder.com/TYMC-1.html but it doesn't mention any special parameters or memory layout.

The flashing starts OK, but consistently gives an error at 8% of the upload.

Brilliant! Thanks. I had it on 3.3V from the FTDI. I thought that fixed the going to sleep issue.
I powered it from the pads, not directly to the module. Maybe that was the reason?
But it is flashed now:-) Moving to phase 2.

Hi Dmartella, will do. Meanwhile can you tell me how you kept it from switching off while configuring it? Does it make a difference if I provide power directly to the ESP8266 module? (A opposite to the broken out pins for 3v3 and GND next to the MCU)

hi blakadder,

have the same sensor now here and working already.
BUT: a question regarding "keep the module powered from the USB-to-serial adapter instead of batteries": I tried this, but I'm failing and i don't know why. I soldered pins to VCC and GND of the ESP - it looks like this:

Doorsensor

The aim is to have it - without soldering - "online" for reconfiguring, if necessary.
But the pins do not work for powering. I have measured with a multimeter, as soon as powered by battery I can see there 3.3V at the pins, so I assume it is soldered well. if I attach (without batteries) 3.3V from the USBtoSerial adapter to the pins nothing happens. If I attach the 3.3V from the adapter to the pins on the board in the middle, it boots, but the MCU disables the ESP as it does in battery mode.

I did not attach RX / TX / GPIO0 anywhere, only the power.
Is there something else necessary besides the VCC/GND pins to have it booting up and staying online?

Thanks for any hints. :-)

Like any other ESP 12F module it is required to pull EN high and GPIO15 low in order for the module to boot into the flashed firmware so your idea won't work. reference http://glyncowles.blogspot.com/2015/07/programming-and-running-esp12-e.html

Hi, I guess, you followed the flashing instructions here: https://github.com/klausahrenberg/WDoorSensor/blob/master/Flashing.md

Then, proceed with initial configuration (Wifi settings): https://github.com/klausahrenberg/WDoorSensor#initial-configuration

After this, the sensor should send messages to your MQTT broker at every door opening/closing in following json structure:

I did it up to install following the instructions. I uploaded the .bin file. but I could not configure it. I power the Esp but I cannot flash the light, do you know which pin corresponds to the reset button on the TUYA in ESP8266.

Thank You.

@klausahrenberg

I'm a little confused. Ok, flashing with esp tool was successfull, right?

  • If so, then remove all connections that you used for programming (GND, VCC, GPIO0, TX, RX).
  • Then insert the batteries, then hold the button (> 5 sec) until the led blinks.
    It's not possible to get in to the configuration in via powering the Tyua/ESP over the programmer.

Yes. I flashed with esp tool.

  • Then I power on VCC and GND pin
  • But I do not know the reset button in Tuya because I made it from ESP so I know that the led is on the D2 pin. Because I can't blink light
  • I'm trying to do this flashing not on the door sensor, but on the Esp8266 12E Module

@klausahrenberg
Copy link

Ok, now I know your idea. But I have to say, it will not work. The door sensor is not just an ESP12E. It has a second controller (MCU) where the reset button, the LED and complete battery management is connected to. MCU and ESP talks via serial communication to each other. ESP does only the WIFI things, the MCU is the logic itself.
So you will not be able to test my firmware with an ESP12E only, please use the door sensor.

Ah, but here is the spec:

https://developer.tuya.com/en/docs/iot/CBxxSerialModuleUART?id=Kajjtxaiaeh5j

In which I can clearly identify pins marks TX1, Tx2, RX1, RX2, GND and 3VC (which I suspect is your VCC) but the RX/TX confusion aside, GPIO is mentioned on 8 pins other! And needs some more skill to read than I have off-hand.

This is based on BK7231N and not an ESP. So it's not Tasmota compatible
You need to brain-swap but there doesn't appear to exist an ESP based module that would be pin-to-pin compatible. So flying wires will be needed.
