Privacy Concerns

Personal Information required for App

To operate Ariston WIFI-enabled water heaters/boilers remotely, users must install the Ariston Net app and register an account. Registration requires personal details including full name, email address and phone number. Adding a device also requires providing the installation address, which is usually the user's home address.

Lack of Local API

The Ariston products do not have a local API or any documentation on their cloud API calls. The lack of documentation leaves the user with no other official way to use their products without using the Ariston Net app. Without a local API, all device actions/statistics must go through Ariston Group’s servers.

Controversies

API Rate Limiting

Although Ariston provides no official support for third-party integrations, users have reverse-engineered the cloud API and created a Home Assistant integration for their water heaters.

On April 30th, 2024, Ariston has started enforcing stricter rate limits on API calls. This broke the integration for many users and, in some cases, even prevented users from using the official Ariston Net app. This left users with no way to control their devices remotely for hours after they hit the limit.

Ariston has not provided an official statement on the rate limits. Although, users have stated that after contacting Ariston support, they were told that Ariston prohibits/does not support third-party integrations.
