Building smart home in a countryside of country A. Currently have close to 50 Aqara devices. Key priority of my setup is resilience, autonomous power supply. Therefore, hubs and cameras (M3, G3 x2, G5Pro x2, G410, Router) are backed with autonomous power supply up to 48 hours. Another smart home setup in a country B, have 20 devices. (Would be cool if Aqara app allowed to make cross-country / cross homes automation.)
