Device overview
IoTaWatt Monitoring Pro Kit is a local-first Wi-Fi electricity monitor for homes and small sites that need more than a single whole-home number. It is best understood as an energy-meter / data-logger device: CT sensors measure mains and branch circuits, while the IoTaWatt hub stores data locally and serves setup, status, graphs, and query access through its own web interface.
Core monitoring fit
The current CircuitIQ V6.4 Pro Kit includes the IoTaWatt hub, power supply, reference voltage adapter, ten 50 A CTs, two 100 A CTs, and two 200 A CTs. That makes it a strong fit for US/Canada split-phase panels where the buyer wants mains plus branch-circuit visibility, but the broader IoTaWatt documentation also supports single-phase and configurable three-phase use with suitable voltage-reference and CT setup.
Local data and integrations
IoTaWatt is unusually local-data friendly. Its official material describes an integrated web server, local history, browser-based configuration, Graph+ views, and a Query API. Optional upload paths include PVOutput, InfluxDB, and Emoncms. Home Assistant has an official IoTaWatt integration using local polling, and its energy documentation covers consumption, export, and solar production outputs.
Solar and import/export use
For solar homes, IoTaWatt can model consumption, grid export, and solar production through configured inputs and outputs. This is not an inverter or battery controller; it is a monitoring layer that can expose the energy data needed by dashboards and automations.
Limits to note
The formal accuracyClass field is left unset because the reviewed official sources did not publish a single IEC/MID-style class for the full kit. Accuracy depends on the chosen CTs, voltage reference setup, calibration, and installation quality. Buyers should also confirm the current CircuitIQ kit contents and regional shipping before purchase.
