Power Trace is a closed-source desktop application for monitoring and analyzing data from Tuya Wi-Fi energy meters. It collects readings via push over the local network, stores them in SQLite, and provides live dashboards and on-demand analysis, with optional remote access via Tailscale. The project is interesting for its focus on local-first data ownership and practical integration of off-the-shelf IoT hardware.

Target audience: homeowners, DIY enthusiasts, and developers interested in IoT and energy monitoring
