The green dot and your status message do different jobs
Slack separates availability from your custom status. A message such as “Working on a proposal” gives teammates context; it does not hold the availability dot active.
Use a clear status message alongside any availability routine so people know whether to expect an immediate reply.
Try one workspace first
Open Slack through the extension’s dedicated tab and sign in normally. Set a short manual session, keep the computer awake, and check what a permitted viewer sees before relying on a recurring schedule.
OnlineHours records activity pulses from its own browser session. Slack still controls the visible result, and the current integration has not completed live compatibility validation.
Why cloud Slack is not offered yet
Slack’s documented users.setPresence method accepts auto or away and requires users:write. “Auto” restores automatic presence; it is not an always-active switch.
OnlineHours does not currently offer a Slack cloud connection. The browser experiment needs your local session to remain running, and it does not ask you to paste Slack session cookies into the website.
Common questions
Will a Slack status emoji keep me active?
No. Custom status text and emoji communicate context; availability is a separate signal.
Can I schedule different workspaces?
Treat each workspace as a separate connection and verify it individually. Do not assume that an activity pulse in one workspace confirms presence in another.
