My Nest smoke alarm was great … right up to the point it went nuts

Re: I had a first gen go wacko

I also had 2 first gen Nests, which were fine until they got to almost 2 years old, and one started false alarming in the middle of the night, which then set the other off in sympathy like howling dogs. Unfortunately they were the mains operated ones with a non-accessible back-up battery so after two nights of false alarms I ended up putting them in the garage wrapped in several blankets so as to hopefully not wake up the whole neighbourhood when they went off again.

I was all set to kill them in a bucket of water the next day if the batteries hadn't run down, but by chance I noticed that because I'd bought them from John Lewis, they were still covered by a two year guarantee. Their CS said I'd need to take them into my local JL, so I ended up having to drive 25 miles with two smoke detectors on the passenger seat next to me, having to hit the silence button when they went off every few minutes. Eventually got to JL half-deaf and exchanged for two v2 versions (which have worked faultlessly since).

Next morning I got a call from the JL store. Did I know any way of stopping these alarms going off every few minutes? They were driving everyone in the store mad and somebody was having to stay near them to mute them all the time so as not to cause staff/customers to think it was a genuine alarm. The back-up battery life in those things must have been incredible.
