7.23 firmware upgrade brings a manufacturer fix for these bulbs. Just a heads up, as they might be turning on by themselves, one last time.
Fixed Linear/GoControl LED Light Bulbs LBZ60-1 and Flood Bulbs LBR30Z-1 randomly turning ON in certain scenarios through Z-Wave OTA device update.
Note: This fix is visible 48h after the upgrade. There is a chance a light will turn ON when the upgrade is complete at night. This would happen one last time post the update and after that the issue will be fixed. This only applies to affected Linear bulbs sold in the U.S. The European version will be addressed in an upcoming release.
