HomeWizard devices join the home Wi-Fi network (2.4 GHz) and talk to the HomeWizard app through HomeWizard's cloud. They also offer a local API on the same network. That API is what Home Assistant, openHAB and community integrations build on, and Home Assistant can be set to cut the devices off from the cloud entirely.
That suits people who want to see and automate energy use, especially with a Dutch-style P1 smart meter port, and who use Home Assistant or similar. It is weaker for mainstream voice and Matter ecosystems: we found no Alexa, Google Home or Matter support from HomeWizard, and Apple Home access relies on community tools.

The main app, also shown as HomeWizard in recent release notes. It shows live and historical power, gas and water use, calculates costs from your tariffs, supports several homes and invited family members, and switches the Energy Socket. The Energy+ upgrade adds longer storage, alerts and automated tasks. The listing also mentions Siri, widgets, Apple Watch and Home Connect appliance control. Published by HomeWizard B.V.

| Connection | |||
| Wi-Fi | Yes | HomeWizard lists 802.11b/g/n (2.4 GHz) Wi-Fi with WPA2 and WPA3 for the P1 Meter and the Energy Socket, and does not mention 5 GHz. The P1 Meter plugs into the smart meter's P1 port and may be powered from it on newer meters, otherwise by USB-C. | HomeWizard P1 Meter HomeWizard Energy Socket |
| Local API | Official | The devices can be read on the local network through an open JSON API. API v1 needs the Local API switch in the app (for the Energy Socket and Watermeter). API v2 uses HTTPS and a token obtained with a button press, with WebSocket updates, and is available for the P1 Meter, kWh Meter and Plug-In Battery. | HomeWizard API getting started HomeWizard API introduction |
| Cloud | Not mentioned | The app works through HomeWizard's cloud. Home Assistant's page says its Cloud connection toggle disables all HomeWizard cloud communication, which also stops app communication and firmware updates. | Home Assistant HomeWizard integration |

| Home Assistant | Official | Built into Home Assistant core since 2022.2 and covering the P1 Meter, Energy Socket, Watermeter, kWh Meters and Plug-In Battery over the local API. It began as a custom integration by a HomeWizard engineer, and HomeWizard joined the Works with Home Assistant program in December 2023. | Home Assistant HomeWizard integration Works with Home Assistant announcement |
| Homey | Community | The HomeWizard app on the Homey store is published by an independent developer, not Athom or HomeWizard, and the listing refers to the official HomeWizard Energy app as a separate product. It lists Homey Cloud, Homey Pro, Homey Pro mini and Self-Hosted Server, yet tags every device Homey Bridge required, and we could not resolve how those fit together. Most devices connect over LAN. | Homey app page |
| openHAB | Yes | openHAB's own HomeWizard binding supports the P1 Meter, kWh Meter, Energy Socket, Watermeter and Plug-In Battery through the local API (v1 or v2). It has no auto-discovery, so an IP address or hostname is needed. We found no sign that HomeWizard maintains it. | openHAB HomeWizard binding |

| HomeWizard local API | Official | HomeWizard publishes API documentation for the P1 Meter, Energy Socket, kWh Meter, Watermeter and Plug-In Battery, aimed at personal automation, home automation and data graphing. It returns only current measurements or device control, not history. Device support differs between v1 and v2, and v1 is planned to be phased out. | HomeWizard API introduction HomeWizard API getting started |
