SHT30 temp/humidity i2c sensor to Kincony B8

[zbarothi]

Hi,

I am trying to connect an SHT30 temperature and humidity i1c sensor to a Kincony B8 using free GPIOs 47 and 48. https://shop.kincony.com/products/sht30-...tion-cable

I have ESPHome firmware on the board with this config:

i2c:

  - id: bus_b
    sda: GPIO47
    scl: GPIO48
    scan: true
    frequency: 100kHz

sensor:
  - platform: sht3xd
    i2c_id: bus_b
    address: 0x44
    update_interval: 60s
    temperature:
      name: "Homerseklet"
      device_class: "temperature"
      state_class: "measurement"
    humidity:
      name: "Paratartalom"
      device_class: "humidity"
      state_class: "measurement"

I have tried many variations, switching the SDA and SCL etc but no luck. The device is not detected. Am I using the correct GPIOs?  (see attached photo)

black -> ground
yellow -> 47
blueish green -> 48
red -> 3V

can you try exchange pin define of SDA and SCL?

can you try exchange pin define of SDA and SCL?

Tried that, also to physically change the wires. Tried on GPIO07&40 as well, 47&40. No luck. Also tried 013&14. Tried with lower frequency, cut the wire shorter to reduce resistance. 

[22:20:29.328][C][i2c.idf:092]: I2C Bus: [22:20:29.328][C][i2c.idf:093]: SDA Pin: GPIO13 [22:20:29.328][C][i2c.idf:093]: SCL Pin: GPIO14 [22:20:29.328][C][i2c.idf:093]: Frequency: 10000 Hz [22:20:29.333][C][i2c.idf:106]: Recovery: failed, SCL is held low on the bus [22:20:29.333][C][i2c.idf:113]: Results from bus scan: [22:20:29.333][C][i2c.idf:115]: Found no devices 

I think I will give up at this point and order another RS485 version.

next week , i will test it, feedback to you.

take a photo of your SHT30 sensor, our sensor is RED,BLACK,YELLOW,WHITE 4 cables.
RED: power
BLACK: GND
YELLOW: SCL
WHITE: SDA
