Hi. I created this tool wifi-heatmapper (https://github.com/hnykda/wifi-heatmapper/) to help me measure and track my WiFi connection at home. You upload a floorplan, click on it, and it generates heatmaps. All locally.

Hope some people find it useful!

This looks very cool!

My question is, how do you get the floorplans to use as the baseline map for this tool?
