It works on the GLAR300m
LNURLw is not maintained at the moment, but payment might work on other routers if you use LNURLw.
You will to make a custom build of nodogsplash for your router if your not using the glar300m and you want to use e-cash instead of LNURLw
This build is super hacky and the strings that nodogsplash accepts are still quite short. Improvements are most welcome 😀
