# Update WMT client code from the controller's WMT_project folder
|
|
# ──────────────────────────────────────────────────────────────────────────
|
|
# Use this for devices that have not yet received the HTTP auto-update,
|
|
# or whenever you need to force a code push from the server.
|
|
#
|
|
# What this playbook does:
|
|
# 1. Ensure WMT directory exists on the target
|
|
# 2. Back up the current app.py as app.py.bak.<version>
|
|
# 3. Copy everything from /home/pi/Desktop/WMT_project/ on the CONTROLLER
|
|
# → /home/pi/Desktop/WMT/ on the TARGET
|
|
# The data/ directory on the target is fully preserved (never touched)
|
|
# 4. Fix file ownership
|
|
# 5. Restart the wmt systemd service
|
|
#
|
|
# The data/ directory (config.txt, idmasa.txt, tag.txt, log.txt, device_info.txt)
|
|
# is intentionally excluded — device-specific settings stay intact.
|

# Run via: Ansible > Playbooks > "Update WMT Code"
