Home Assistant Cloud
Home Assistant Cloud by Nabu Casa provides remote access and voice integrations for Home Assistant, the leading open-source home automation platform.
What is Home Assistant Cloud?
Home Assistant Cloud — sold as a subscription called Nabu Casa — occupies a philosophically unusual position in the smart home ecosystem. Home Assistant itself is an open-source home automation platform that runs on local hardware and is explicitly designed to keep control local, avoiding dependence on any manufacturer's cloud. Nabu Casa's cloud subscription adds the features that genuinely require cloud infrastructure — remote access from outside the home network without port forwarding, voice assistant integration with Amazon Alexa and Google Assistant, and webhook relay for external integrations. The subscription funds ongoing Home Assistant development, making it both a product and a funding mechanism for the open-source project.
Because Home Assistant Cloud is opt-in rather than architecturally mandatory, the relationship between cloud availability and home automation functionality is more clearly defined than with most smart home platforms. If Nabu Casa's cloud is down, everything that runs purely locally — automations, local device control, scenes, the local dashboard — continues working without interruption. What breaks is specific to the cloud features: remote access from outside the home (the remote UI bridge stops working), Alexa and Google Assistant voice commands to Home Assistant stop functioning, and any cloud webhooks used to receive external triggers fail to arrive. For users who rely heavily on voice control and remote access, this is still a meaningful disruption.
Nabu Casa cloud outages tend to be clearly communicated on the company's status page, as the open-source community around Home Assistant tends to report and discuss problems quickly. Remote UI connections time out, leaving users who are away from home unable to access their dashboard or make manual automation changes. Alexa skills that proxy through Nabu Casa stop responding to home control commands, even though the Home Assistant instance itself is running and healthy. Webhook-triggered automations — for instance, receiving a notification from a UPS package tracking integration — fail to arrive when the relay infrastructure is down.
Outage.gg tracks Home Assistant Cloud service status using community reports from Home Assistant users and smart home enthusiasts. If remote access has stopped working, voice assistant integration is broken, or webhooks are not arriving, the live status page shows whether there is a Nabu Casa cloud issue.
