Valetudo Companion uses Bonjour/Zeroconf to find robot vacuums running Valetudo version 2021.08.0 and up. It displays each found vacuum in a list and lets you open the control panel in your browser with a single tap. It also allows you to join a robot running Valetudo to your Wi-Fi network without having to mess with your mobile data settings or figuring out your robot's IP.
