I have 3 bulbs of type L535E - bought them at the same time.

2 are on: firmware 1.1.8 Build 240708 Rel.165207 (hardware V3.0)

1 offered a firmware update during setup and is on: 1.4.1 Build 251016 Rel.204554 (hardware V3.0)

How can I get the other 2 onto the newest firmware as well? I tried both official methods (via profile page for all devices at once, via accessory page for each device individually) but it say's it's all up to date.

Thanks a bunch.
