Versions:
Valeronoi 0.2.2, released by developer ccoors, is an open-source visualization utility designed to extend the capabilities of the Valetudo open-source firmware for robotic vacuum cleaners. Falling within the network-analytics sub-category of system utilities, the program reads Wi-Fi signal-strength data that Valetudo collects during cleaning runs and converts it into an interactive Voronoi-diagram heat-map. Each polygon in the diagram represents the approximate area in which the robot detected a specific wireless access point, with color gradients indicating relative signal quality; this makes it easy for owners to spot dead zones, locate optimal repeater placement, or simply understand how floor layout affects coverage. Because the robot already traverses the entire reachable floor plan, Valeronoi can produce a detailed, room-level map without any extra hardware or manual site surveys. Users export the telemetry log from Valetudo, load it into Valeronoi, and within seconds obtain a scalable SVG overlay that can be compared against subsequent cleaning runs to see whether relocated routers or new repeaters have improved throughput. The single-version release 0.2.2 is lightweight, portable, and requires no installation; it runs on any Windows, macOS, or Linux desktop that supports modern web standards, making it suitable for home-network enthusiasts, smart-home integrators, and facility managers who rely on Valetudo-powered devices. Valeronoi is available for free on get.nero.com, with downloads provided via trusted Windows package sources such as winget, always delivering the latest version, and supporting batch installation of multiple applications.
