4. Please describe the bug / issue. Attaching any relevant screenshots would be very helpful! Thanks in advance.

I’m getting the following error when trying to add a TSL256 sensor:
Please fix the following errors:
Failed to add the sensor, please re-check your settings. Make sure you selected the correct Channel/Slave Address.

From the following code I’m assuming I should select 39 as the address? I have 29, 39, and 49 but none of them worked.

39 is the correct default address to use for the TSL2561. Weird. Can you post a screen shot of your setup?

Hmm I just tried again and it seemed like the page locked up, I waited about 2 full minutes. Then I refreshed and tried again and it said the sensor was already added, so I went back to the dashboard, and there it was!
