The device collects nearly 25 data points (consumption, feed-in, phase parameters, etc.) from the meter and forwards them via MQTT, Home Assistant, JSON API endpoints, to the cloud or local network. Thanks to the JSON API output, it is easily integrable with Grafana and InfluxDB systems as well. It also has its own web server (http://okosvillanyora.local:8989/), where data can be viewed. Remote monitoring is available over Wi-Fi connection. Supports OTA updates.

In addition to local data outputs, remote access can be freely used with okosvillanyora.hu and hmke.app cloud services. If used with Home Assistant, data storage is done on the local network within the Home Assistant system.

The device's Home Assistant integration can be downloaded from HACS. This integration can distinguish multiple devices if using ADA One for multiple meters.

For the above-mentioned cloud services, there is an option for remote data storage, which is fee-based. More information can be found at the https://okosvillanyora.hu website. All our additional cloud-based services are available with a subscription (annual or monthly). We provide free cloud service for pensioners.
