How to connect 4 BH1750 sensors to ESP32 with Tasmota? I2C configuration

ESP 32 and 4 pieces of BH1750 sensors.
Hello I would like to connect 4 pieces of BH1750 under one ESP32 on Tasmot how should this be done ?
Should I set up 4 I2C buses on different GPIO ? And to each separately connect the individual BH1750 sensors ??

I would start with Tasmota's documentation, but it doesn't talk about many devices:
https://tasmota.github.io/docs/BH1750/
And if the documentation is silent, you should check Github:
https://github.com/search?q=repo%3Aarendst%2FTasmota%20BH1750%20&type=code
https://github.com/arendst/Tasmota/blob/ddcdc...ta/tasmota_xsns_sensor/xsns_10_bh1750.ino#L81
From what I can see they detect BH1750 as follows:
.
That is, two buses and two sensors on each....

Addresses:
.
With this knowledge I would start by trying to connect two BH1750s to one I2C, but so that each has a different address. .
And as for the second I2C bus, do you have any SDA1 and SCL1 and SDA2 and SCL2 there separately? Because as far as I can see there must be two buses of 2 sensors each.

EDIT: I've read it again and I don't like it:
.
And the size in general of this board.... it looks like they have a hard limit of two sensors. But run the two to start with and we'll think, you can always change their code and compile your own version of Tasmota.

I've just caught up once before somewhere on the web with what you pasted about addresses but there was no time to connect.
So the result:

I have just set it up like this:

.

Unfortunately it only sees two sensors on bus 1 GPIO 21 and 22 on the other bus it does not.

I'm looking in the history but can't find it.

Well unfortunately the author of the code there did not foresee more than two sensors, you have to at least change this condition with two and here the size of the array:
.
It is also worthwhile, instead of writing "2" from your finger, to enter some #define MAX_BH1750_SENSORS 4 .

It is also possible that other places in the code may need to be changed, I haven't analysed this thoroughly.

What do you need these four sensors for? Probably in the PlatformIO you would also run them quickly on the ESP....

We are giving up on the subject of connecting 4 sensors to one ESP32 on the grounds that I can use 2 ESP32 units and connect two sensors to each.

And now the best and funniest topic:

I want to have four different controlled readings in numbers in Domoticz so that I can try to arrange the appropriate event in blockly.
I thought that in order to have control I would use four light sensors and place each sensor in a separate cardboard box to have control over the light given and simulate the readings in domoticz.
In this way I will test the operation of the stacked event in blockly.
