Pick one primary control path first
The TP-Link integration can expose vendor-specific data, while Matter offers a standardized controller path. Set up and verify one path before adding another so duplicate entities do not obscure which connection supplies power data.
Confirm entities after every update
Matter energy support, device firmware, and Home Assistant releases evolve. Check current power, accumulated energy, units, availability, and update interval instead of assuming a screenshot from another version matches the present system.
Keep the Tapo app for firmware and diagnosis
Even a local Home Assistant workflow benefits from the vendor app for initial setup, firmware, model verification, and a baseline view of energy data. Document credentials and ownership without exposing them in dashboards or public logs.
Test recovery
Restart Home Assistant, reboot the plug, and temporarily interrupt internet access while a noncritical load is connected. Confirm which controls and history survive before depending on an automation.
