What the fuck is chirping away every 38 seconds in my house?
Ruled out burglar alarm and carbon monoxide alarm. Current guess is a smoke alarm. They're mains powered and not showing any error light but I guess they must have a battery backup or something but I can't work out which one is making the noise.
