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.

Engineers have since been "continuing to work on a fix for this issue".

This couldn't have happened at a worse time for app happy users, what with an incoming polar plume from Iceland set to cause temperatures to tumble to as low as -5°C in parts of the UK. Those that can will be forced to intervene manually. There will be those that can't.

Naturally, some of Centrica's Hive customers leapt onto Twitter to complain.

There’s a major outage on the Hive network so I’ve just had to adjust my thermostat by hand, like some sort of troglodyte. — Charl 🇪🇺 (@finchill) April 2, 2019

@BritishGasHelp my hive system says major outage. I have no heating or hot water. What’s the issue please and how long until it's fixed. — Mike (@MikeJoiner1965) April 2, 2019

The Reg has asked Centrica to comment. ®
