Aqara switches are somewhat very common zigbee light switches. I moved to these a few years ago and they worked without an issue up until about now. And now, guess what: Mechanics failed. So I decided to document 2 different ways of fixing them in this very post
I decided to describe in detail a proper replacement for Xiaomi Aqara Zigbee Gateway. CC2531-based and CC2538-based to be precise and gather all the relevant stuff about flashing and preparing those in one place.
This is my second note about Xiaomi Aqara smart home stuff. Something tells me it’s not the last one. In this note I’ll tell about implementing home automation that will reliably work offline using readily available hardware from Xiaomi and (at the same time) keeping your privacy intact. After all, not everyone is ready to share all the private stuff with some corporate crooks 
There are some pretty good smart light switches called Xiaomi Aqara. It’s basically a light switch with a relay and Zigbee wireless interface inside. They are integrated with Xiaomi zigbee gateway and can be remotely controlled. Zigbee gateway uses them as a proxy in case the battery-powered sensor is not in the direct range. This post will be about adding a better wall-mount box for those little things.
