Checking…
Asking the backend for its health.
This page asks the API itself, in your browser, when you load it. It is not a dashboard we update by hand, and it will tell you when it cannot get an answer rather than showing you a green tick.
Asking the backend for its health.
That the API is reachable and its database schema matches the code it is running. That is the check the deployment platform itself uses, so a release whose migration has not been applied fails it and the previous release keeps serving.
Whether your battery is being read. That depends on your manufacturer's cloud, which we do not control and cannot speak for. If your readings stop, the app shows you the gap on your own system's page, and that is the authoritative answer for your house, not this page.
There is no maintenance window: the beta is deployed continuously, and because the service is read-only an interruption costs visibility rather than electricity.
That is worth knowing about. Tell us what you are seeing.
