I stumbled across this git by chance. I already have a couple of gravity sensors working in my pool but this looks to be a much more elegant solution so I purchased the feather v2 and accessories. However I'm struggling to get it work as I dont think I am approaching the installation correctly.
"copy wifi_example.yaml to wifi.yaml and edit the new file
Connect the board via USB and enter esphome run tubby.yaml"
Could you elaborate on how you perform these steps? I'm used to flashing the esp with esphome and then pasting the yaml into it.. However there seem to be a number of dependancies here which means it fails to compile. Could you add a bit more detail for idiots like me? Id really love to get this working!
