I am using a ESP32 Camera board with the following sensors in ESPHome (Light Sensor BH1750FVI and Pressure+Temperture+Gas Sensor BME680). I have everything working with the exception of the Light Sensor BH1750FVI. I have the BME680 and the BH1750FVI wired to the same bus on the ESP32 Camera board. The wires are labeled correct for SCL and SDA. I do not have the address line from the BH1750FVI hooked up to anything. I have tried several configurations on wiring and in ESPHome to recongize the sensor and to date all it says is “unknown”. I have also tried different frequencies on the BH1750FVI with no success.
Please help me resolve this issue and to get the sensor working on the same I2C bus as the BME680. The camera bus is not accessible on the pin configuration for this board. See below.
Thanks in advance!!!

For start you have address 0x23 stated for light sensor in your program, while log finds device on address 0x3C, not on 0x23 (and 0x77 which is your other sensor). Try changing 0x23 to 0x3C and see.
So you connect both the BME680 and the BH1750FVI to the same pins, like is shown in your scheme as well. But then why are you defining different pins for them?
Try to configure it like this, so with both devices using GPIO41 and GPIO42
i2c:
sda: GPIO42
scl: GPIO41
scan: true # This will list detected addresses in logs
frequency: 100000 # might need to be changed
# temperature
bme68x_bsec2_i2c:
address: 0x77
model: bme680
operating_age: 28d
sample_rate: LP
supply_voltage: 3.3V

# # 0x23 for low and 0x5C for high

Like this you don´t need to define separate I2C bus id’s

That device at 0x3C is on the other bus, so probably the camera.
Have you tried something simple with just the BH1750DVI hooked up?
Right now there are too many unknowns. It could be the sensor is defective. It could be hooked up incorrectly. It could be conflicting with the other sensor.
Have you tried a different esp board without all the other stuff?

From the letscontrolit site
Your BH1750 does not show up at I²C-scan
Usually this failure results of cabling faults. If your device does not show up, SCL and SCA might be swapped or the module does not get power or ground. If you are testing on a breadboard, the breadboard contacts might be worn out or you got some faulty cables. A digital multimeter will help with this situations.
Great solutions. To answer some questions: The GPIO pins 4 and 5 are not hooked up to either the BH1750FVI or the BME680 sensors, so yes that is the camera on the ESP32Cam board. The BH1750FVI and the BME680 are hooked up to pins GPIO 41 & 42. Address 0x77 that is recognized in the i2c scan is the BME680 board per the yaml. Readings on it have been perfect. So yes the biggest problem I have is non-recognition of the BH1750FVI showing up at all. I did buy two of these sensors and will play around with the cables / sensor to see if I can get ESPHome to recognize the sensor during the sensor scan.
Let me know if anyone has other thoughts for sure.
I am wrong here: you are using GPIO04 / GPIO05 for the camera I2C only, via bus id: camera_i2c and GPIO42 / GPIO41 for both the BME680 and BH1750VFI via bus id: bus_b
There is no wrong here for sure. I appreciate the help. Going to troubleshoot today.
Ok did some quick double checking. Put a new BH1750FVI sensor on the wiring and it popped up immediately !!! Problem solved!!!
So appreciate all the help to overlook to make sure I wasn’t missing anything. Sometimes it takes a collective to get these sensors / configurations to work. Have a great day everyone!!!
