Hi
I bought a netro Sprite controller and have been using the app for a couple of weeks now. I find the Spanish translation quite bad. Looks like a direct Google translation.
I can help you in the translation if you want. Feel free to ask me for help if you want.
I would also love to be able to integrate netro with Google home. Currently I can't find it in my Google home app because of the lack of Spanish translation. I can help you with that if you want.
Apart from the Spanish translation problems, I think you have a great app and devices. Congratulations!
