I use ESP8266-12E board, but only 3 I/O port pin already free.
But I would like yet use INA219, DHT22, HX711 and DS18B20 sensors on one I2C bus.
Is possible on one I2C bus ?
Can you help me ?
Thanks.

YUP!
From a quick look at datasheets all these devices have a different interface. only the INA219 has a i2c interface.
I want to connect ESP12E as master communicate i2c with Arduino Uno as slave and i2c with OLED 0.96.
But I can only connect 2 of them each time. Either ESP with OLED or ESP with UNO. Any idea how I can do this? I want to capture data with UNO and send to ESP( and other calculation) and display values.
Any help will be very much helpful. Thanks in advance.
