systemd Deployment

The service uses systemd for process management and scheduled tasks.

Main Service

sudo cp 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

Session Snapshot (every 5 minutes)

Saves current active session conversations to diary files, preventing data loss from session compression.

mkdir -p ~/.config/systemd/user/
cp systemd/mem0-snapshot.service ~/.config/systemd/user/
cp systemd/mem0-snapshot.timer ~/.config/systemd/user/

systemctl --user daemon-reload
systemctl --user enable --now mem0-snapshot.timer

Auto Digest (every 15 minutes)

Extracts short-term events from diary files and stores them in mem0 with infer=False (run_id=YYYY-MM-DD). Diary text is passed directly to mem0 without a custom LLM extraction layer.

# 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 mem0-dream.service /etc/systemd/system/
sudo cp 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-snapshot.timer
sudo systemctl list-timers mem0-dream.timer

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

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