• Current Status: High-frequency tasks execute every 15 minutes (meets requirement)
• Config File: ~/.openclaw/openclaw.json
• If modification needed, inform user of the method:

  # Backup original config
  cp ~/.openclaw/openclaw.json ~/.openclaw/openclaw.json.backup.$(date +%Y%m%d_%H%M%S)
  
  # Modify heartbeat config (add to agents.defaults or specific agent)
  # "heartbeat": {
  #   "every": "45m"
  # }

2. State Tracking File

• File Location: /home/${user}/.openclaw/workspace/memory/heartbeat-state.json
• Required Fields:

  {
    "lastWaterReminder": 1772681220,
    "chatId": "SESSION_CHAT_ID"
  }

Execution Logic

Time Check

1. Get current time (Example: GMT+8 timezone) converted to 24-hour format
2. Check if within 8:00-23:00 range
3. If outside working hours, skip reminder

Interval Check

1. Read lastWaterReminder timestamp from memory/heartbeat-state.json
2. Calculate time difference between current time and last reminder
3. If difference ≥ 45 minutes (2700 seconds), execute reminder

Reminder Execution

1. Update lastWaterReminder with current timestamp
2. Save back to memory/heartbeat-state.json
3. Send reminder message via the agent's configured channel to user's session
