Yes it can work, but not in all cases. I believe it will only work with modes REMOTEXY_MODE__ESP8266WIFI_LIB and REMOTEXY_MODE__ESP8266WIFI_LIB_CLOUD.

If you want it to work with mode REMOTEXY_MODE__ESP8266WIFI_LIB_POINT or whatever, then it will require some work, like creating your own RemoteXY module, basically copying the module you want and change or remove a few things in the initModule() function.

This is what I did because I prefer to have control of WiFi.mode and WiFi.begin. Multiple calls to those functions is problematic, and the RemoteXY modules clearly aren't made with that in mind!

Thanks!
