问题 I have implemented a home automation solution to track my childrens chores using two Amazon Dash buttons, a raspberry pi, and python code similar to what's been done here. This solution has worked for the past several months. Yesterday, the buttons appear to have ceased ARPing. That is, I can no longer detect an ARP from them, nor do I appear to be able to detect their MAC address by sniffing it. I'm wondering if anyone else has had this problem? In addition to the python mechanism using
