systemd Deployment

The service uses systemd for process management and scheduled tasks.

Main Service

sudo cp systemd/mem0-memory.service /etc/systemd/system/
# Edit User/WorkingDirectory/EnvironmentFile paths as needed
sudo systemctl daemon-reload
sudo systemctl enable --now mem0-memory

Scheduled Tasks

Diary Capture (Real-time via openclaw-plugin)

Diary files are written in real-time by the openclaw-plugin agent_end hook — no separate timer or polling process is needed. The plugin fires after each agent turn and writes the conversation to the agent's diary file.

Note: The previous session_snapshot.py (every 5 minutes) and its mem0-snapshot.timer have been retired. If you have them installed, you can safely disable and remove them:

systemctl --user disable --now mem0-snapshot.timer
rm ~/.config/systemd/user/mem0-snapshot.{service,timer}
systemctl --user daemon-reload

Auto Digest (every 15 minutes)

Extracts short-term events from diary files and stores them in mem0 with infer=True (run_id=YYYY-MM-DD). mem0 runs internal fact extraction to produce concise short-term memories.

# Using cron
(crontab -l 2>/dev/null; echo "*/15 * * * * /usr/bin/python3 /path/to/auto_digest.py >> /path/to/auto_digest.log 2>&1") | crontab -

AutoDream (daily at UTC 02:00)

Runs nightly consolidation in two steps:

• Step 1: Reads yesterday diary → mem0.add(infer=True, no run_id) → long-term memory
• Step 2: For each 7-day-old short-term memory, calls mem0.add(infer=True, no run_id) — mem0 decides ADD/UPDATE/DELETE/NONE — then deletes the original entry

sudo cp systemd/mem0-dream.service /etc/systemd/system/
sudo cp systemd/mem0-dream.timer /etc/systemd/system/

sudo systemctl daemon-reload
sudo systemctl enable --now mem0-dream.timer

Verify Timers

# Check timer status
systemctl --user list-timers mem0-digest.timer
sudo systemctl list-timers mem0-dream.timer

# Manually trigger
systemctl --user start mem0-digest.service
sudo systemctl start mem0-dream.service

# View logs
journalctl --user -u mem0-digest.service -f
journalctl -u mem0-dream.service -f
