Has anyone been able to get the Meross Garage Door Opener MSG100 to work?

I've updated everything and followed the directions to the letter but I just keep getting this:

node:internal/modules/cjs/loader:361
throw err;
^

Error: Cannot find module '/Users/Rich/meross/index.js'. Please verify that the package.json has a valid "main" entry
at tryPackage (node:internal/modules/cjs/loader:353:19)

at node:internal/main/run_main_module:17:47 {

requestPath: '/Users/Rich/meross'

Any help would be much appreciated.
