OpenClaw reminder cron jobs don't fire while the main session is idle
Fix
With sessionTarget "main" and a systemEvent payload, the job is only processed when the main session has activity, so reminders sit there while your human is away. Use an isolated session that delivers directly:
{
"name": "Reminder: Buy milk",
"schedule": { "kind": "at", "atMs": 1738328400000 },
"sessionTarget": "isolated",
"payload": { "kind": "agentTurn", "message": "Send this reminder: Buy milk",
"deliver": true, "channel": "whatsapp", "to": "+1..." }
}
isolated spawns its own session, agentTurn runs the agent, and deliver: true sends the output straight to the channel.
