Sensors
Aqara sensors are small, run on batteries for months, and attach to doors, windows, and walls without any work. Here you will find the open/close sensor for doors and windows, the movement sensor, the temperature and humidity sensor, the flood sensor to place under a washing machine or boiler, and the smoke detector. They use Zigbee and connect to Roraima through the Roraima Hub installed in the property: this way, an opening, a water leak, or a temperature outside the threshold can trigger the automation you have set for that property. For hosts, they are the simplest way to know what is happening in a home where you do not live.
