@Eilleesy I suggest you post your code and any error messages you get. A link to the library you want to use might also be useful.

@George-Laynes said in OpenHAB 2.1 keeps showing light level as 0 with BH1750 and V_LEVEL: Any idea on how soon it'll be available for general public? Very soon. The next release is finished in the next days. But it will not be backwards compatible because there was a change in the naming of the parameters, for example: skipStartupCheck is now named startupCheckEnabled, so I need to think about migration options.

@GertSanders Then I'll temporaraly switch over to a serial gateway. Thanks again for the info!
