Medtrum EasyView — Home Assistant Integration

🇬🇧 English | 🇮🇹 Italiano

---

This integration allows you to display real-time CGM (Continuous Glucose Monitor) data from Medtrum sensors in Home Assistant, read via the EasyView cloud.

---

How it works

The Medtrum CGM sensor transmits data to the EasyView app on the patient's phone. Via the Follow sharing feature, this data is sent to the cloud and made available to a second account through the EasyView Follow function.

The Home Assistant integration connects to this Follow account to read the data in real time.

---

Prerequisites

• An active Medtrum CGM sensor
• The EasyView app installed on the patient's phone, with a registered Medtrum account
• A second Medtrum account to use as a Follow account (can be a secondary account of yours)
• Home Assistant with HACS installed
