Can't add tsl2561

Thank you for taking the time to submit your bug/issue! Please use the points below as a guide when submitting.

  • Device & model you are using (Ex: Pi 2 Model B or Arduino Uno with W5100 ethernet shield)
    Rpi 3
  • What dashboard are you using? (Web, iOS, Android)
    Web and iOS
  • Please describe the bug / issue as detailed as possible. Attaching the code and any relevant screenshots would be very helpful!

Cannot add tsl2561 on the web browser even tho I have followed the tutorial to the letter. I get the message to be sure I have selected the correct slave address. The sensor is not addressed so according to your tutorial 0x39 is the default setting. None of the 3 addresses work. I can however add on iOS but that fails to all outward appearances but the sensor shows up on web but does not function.

I have noticed differences in analog readings between web and iOS. 3.3volts on web and 1 volt on iOS. Could it be that iOS is just not syncing up properly?

Try running this command: sudo i2cdetect -y 1

You should see output similar to the screen shot here (but instead of 77 you will see your actual address): Configuring the Pi for I2C | Using the BMP085/180 with Raspberry Pi or Beaglebone Black | Adafruit Learning System

If you don’t get anything showing up there double check your wiring.
