Hi @Helimarc,
Thank you for posting here in the Roku Community!
We understand you want to know if the Roku smart home bulb can be linked to multiple Roku accounts. We're happy to help. Please be advised that you can only access one Roku account at a time. If you would like to access all of your Roku Smart Home devices, you can always link everything to the same Roku account.
If there's anything else that we can do to assist you, please keep us posted.
Best regards,
John
