Sensor Thermocouple SHT30 not working despite Wiki says otherwise

[rubenkr]

PROBLEM DESCRIPTION

Attached a SHT30 sensor inside a thermocouple for high humidity to a ESP8266 board. I am using the latest Tasmota 11.0.0.2 by Theo Arends. Followed Wiki Article https://www.wemos.cc/en/latest/d1_mini_shield/sht30.html for wiring as follows:

Wiring SHT30

red = VCC 3,3V yellow = SGK blue = DATA green = GND

Wiring ESP82 -> SHT30

• SDA Pin of SHT30 to D2
• SCL Pin of SHT30 to D1

Tasmota Generic

D2 GPIO4 -- I2C SCA D1 GPIO5 -- I2C SCL

What is the result of command 'i2cscan'? It is preferable to disable unnecessary I2cdrivers with command 'i2cdriver 0' and only keep the minimum number enabled

thank you very much @barbudor for helping me out!

18:09:42.799 RSL: RESULT = {"I2CScan":"No devices found"}

18:10:54.593 CMD: i2cdriver 0 18:10:54.602 RSL: RESULT = {"I2CDriver":"!1,2,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,28,29,30,31,32,34,35,36,40,41,42,43,44,45,46,48,49,50,51,52,53,55,56,58,59,60,61,62,63"}

I unscrewed the thermocoupler to see whats really inside. Is this really a SHT30 board?
