British Gas-owned Hive confirmed the issue in a statement to The Memo: "We are aware of a temporary glitch affecting a very small number of customers, where a certain sequence of commands in the Hive iOS app can cause the thermostat temperature to rise to 32°C." It also noted that the problem could be easily fixed by manually turning the temperature down using "the app, web dashboard or the thermostat itself."

That didn't stop some customers from taking to Twitter to voice their surprise and frustration:

Although the glitch appears pretty simple to rectify, Hive's support team says the company is already working on an update that will patch the issue and ensure that customers will no longer be baked beyond their preset limit.
