Brit energy company Centrica's Hive smart home devices went missing in action this morning with a major outage confirmed across much of the app estate, forcing users to tweak manual controls for heating, hot water and surveillance cameras.

Login wobbles, as revealed by the status page, began at 9:44 UTC across the HiveHome website, dashboard and mobile app, Hive Active Heating, Hive View and "other" products. Only Hive Leak – used to spot leaks around the home – was working as Centrica intended.
