November 28th

After being woken up a few weeks ago by a smoke alarm beeping for a new backup battery,  I've bought new smoke alarms, as apparently they only last 10 years, and I've been here for 16.  Anyway, they arrived today, so I got started installing them.  You do all the WiFi setup to the first one, then they should be able to sync themselves.  I got 2 set up, then the next 2 would fail when "adding to your Nest account".  Sounds like a problem with their account system, so I ended up calling them about it.  We managed to get one to work, but the next one wouldn't, so we agreed to leave it a few hours like the error message suggested.  Just as well, as I needed to get set for work anyway.
