Features & Capabilities

Watt for Smart Devices is the go-to companion app for TP-Link Kasa and Tapo devices, designed for iOS, iPadOS, and macOS. It offers a clean, modern interface that lets you control compatible devices from a single app, with the note that security cameras are not supported.

Key features include energy monitoring with daily-updated charts (showing watts and cost estimates), CSV export, Siri voice control to turn devices on/off or run shortcuts, Night Mode to dim device LEDs, and room-based organization for easy management. Watt supports a wide range of devices — smart plugs with energy monitoring, smart bulbs, and more — and provides home screen widgets for quick access. This is a third-party app not affiliated with TP-Link, and it includes a roadmap link for future updates.

User Reviews

Users largely praise Watt for Smart Devices for clear energy insights and per-device/per-space monitoring, plus features like Siri integration. However, recurring issues include chart data gaps and bugs, stability/login problems, device compatibility gaps with certain Kasa devices, privacy/export concerns, and several feature wishlists (renaming devices, tagging, per-space graphs, export, schedules). Overall value is strong for energy monitoring, but stability and feature gaps affect some users.

Pros

Strong energy usage monitoring with per-device/space breakdown and an intuitive UI.
Adds valuable features to the Kasa ecosystem (Siri integration, power monitoring, and the ability to group devices by space or room).
Reliable, detailed energy data that provides more insight than the built-in Kasa/Smart Home apps.
Responsive development and ongoing improvements.
Per-space grouping and quick control to turn off all devices in a space.

Cons

Charts often show data only in year view; month/day/week data is missing or not updating for some devices.
Stability and startup/login issues: crashes on launch, session expiry errors, and compatibility problems on macOS.
Device compatibility gaps: not supporting some Kasa devices (e.g., HS200) and newer models (EP25/EP40).
Privacy and data export concerns: reliance on Kasa login in a third-party app and lack of data export options.
Feature gaps / wishlist items: need for renaming devices, tagging, per-space graphs, data export, and automation scheduling.
