Shelly 1 with TL (teleruptor) need help

Hardware
1

Need help on wiring or configuring shelly to work with TL (TL - 15520) i want to make this TL smart if i can.
So i wired my house with this type of teleruptors for switching same lighting for more then 2 locations and i want to use shelly to command this from my phone.

my initial try was to command A1/A2 with internal shelly contact, shelly need to be push button.
so TL works with push buttons, one push lights ON, another push lights OFF.

i will attach TL schematic

this is classic shelly 1 schematic

and this is my wiring (maybee wrong)

the light get L,N from TL NO contacts (20amps) 1 - 2 for L and 3 - 4 for N

so i test this configuration with shelly button type on toggle and momentary (both don’t work well)
with toggle set it’s working like this:

from physical push button it’s working (but button state on web interface doesn’t change )

i don’t know how to explain but i will try to describe what happens

it’s a 5 step cycle

1. step

lights OFF
TL - OFF state (no buzzing)
state light - OFF (state of switch on web interface)

2. step

press button from web interface
light ON
TL - ON state (relay start buzzing, like i keep press physical button)
state light - ON

3. step

press button from web interface
light ON
TL - ON state (no buzzing)
state light - OFF

4. step

press button from web interface
light OFF
TL - OFF state (relay start buzzing, like i keep press physical button)
state light - ON

  1. step

press button from web interface
light OFF
TL - OFF state (no buzzing)
state light - OFF

now if i change to momentary button type i must press 2 times the physical button to get the correct TL relay state for light to turn ON or OFF

i am open to any suggestion :roll_eyes:

So i found something that will getting close to what i want.
so i can set in shelly UI Timer - AUTO OFF
i can se t auto off to 1 sec, witch its kind of OK, but its was more ok if i can set like 500ms or 300ms
so i let button type as toggle - like this TL relay works fine when i use physical push buttons, the down side of this the feedback icon on shelly UI doesn’t change so i don’t know real state of the lights
and when i choose to control the lights from shelly UI after i press the button lights go ON and after 1sec TL relay get unpowered, same thing if i want to turn it OFF, i press the UI button lights go OFF and after 1sec TL relay get unpowered. If i don’t use this 1sec timer off TL relay will buzzing and its’ not good.
So it’s kind of working but i never know real lights state if i 'm not near them.

or maybe there is some automation in home assist when i press UI button to send 2 impulse one with 300ms delay , but this second impuls to not change button state?
