Which home energy monitor actually keeps working with Home Assistant when the internet is down?

Emporia Vue Gen 2 was the only major platform in our testing that maintained full local functionality during multi-day internet outages. Real-time power data, circuit-level readings, and Home Assistant automations continued without cloud connectivity. Sense and Leviton lost meaningful data access within minutes. Lumin's advanced features became unavailable.

Does Sense have good local control in 2026?

Not really. Sense is heavily cloud-dependent. During our outage tests, Sense could still provide very basic on-device data, but all advanced features, device detection history, and Home Assistant integrations that depended on the cloud stopped working. Emporia had far better native local control.

Are Leviton and Lumin viable for Home Assistant users who want local control?

Leviton and Lumin have limited or no meaningful local control capabilities. Leviton loses most data access without the cloud. Lumin requires cloud connectivity for advanced load control and solar features. For Home Assistant users who want local control for energy monitoring, Emporia is the only viable major option in 2026.

Can I access real-time power data locally with Emporia Vue Gen 2?

Yes. Emporia Vue Gen 2 supports local polling through its API and integrates deeply with Home Assistant. During our multi-day outage tests, real-time whole-home and circuit-level data continued to flow without any internet connection. This is the key differentiator versus Sense, Leviton, and Lumin.

What happens to my energy automations during a 3-day internet outage?

With Emporia Vue Gen 2 and proper Home Assistant setup, all real-time data and automations will continue. With Sense, Leviton, or Lumin, you will lose most or all advanced features immediately and the system will only provide very basic on-device data (if any) until connectivity is restored.

Meilleur moniteur d'énergie domestique pour Home Assistant et contrôle local 2026

Nous avons testé les moniteurs d'énergie domestique spécifiquement pour l'intégration Home Assistant et le contrôle local. Quelles plateformes fonctionnent vraiment pendant les pannes internet, et lesquelles nécessitent une connexion cloud permanente ?

Recommandation pour Home Assistant et contrôle local

Pour les utilisateurs de Home Assistant et ceux qui veulent un contrôle local, l'Emporia Vue Gen 2 et le Leviton sont les meilleurs choix. Ils offrent une intégration locale fiable via des plugins Home Assistant, et continuent de fonctionner pendant les pannes internet. Le Sense est plus dépendant du cloud et perd des fonctionnalités en mode local. Lumin est bon pour les installations simples mais moins adapté à un usage local avancé.
