Hello Phil!
Thank you for your interest in Eve Thermo Control / the Eve Thermo firmware update with Matter support. Unfortunately, despite our team's best efforts, the completion of the product and the update has taken longer than planned, so the launch date announced at IFA 2023 has been postponed by around three weeks. We very much regret this and hope for your understanding.

As with all updates from HomeKit to Matter, a complete Apple environment with iPhone and Thread Border Router is required, i.e. HomePod mini or HomePod (2nd generation) and/or the Apple TV 4K (2nd generation) or Apple TV 4K (3rd generation, Wi-Fi + Ethernet).
Best regards, Volker
