I didn't notice any beeping or lights.
Yesterday I received a bizarre email from another neighbor requesting help, but without details. The message was strange, but plausible enough for me to reply with a generic "ok... what's up?" Turns out that our neighbor's email account had been hijacked and the perpetrator was fishing for money (a second message asked that I go out and buy four cash cards worth 250 euros each and transmit the codes to the scammer by email). I didn't reply again. Ken called the neighbor's husband to alert him, and he confirmed that someone else had told him they received the same message and that it was, indeed, a scam. I immediately changed my email password. I hope our neighbor can clear it up quickly; she's the mayor of our town.
