@zamorae great to see that MySensors seems to be a good fit. Welcome to the community MySensors is available with two licenses: GPLv2 and commercial. GPLv2 basically means you can use it for free as long as any code you develop is also made available for free. This means everyone benefits from improvements made by everyone. If you want to keep a commercial solution "secret" you can buy the commercial license. Some details are available at https://www.mysensors.org/about/mysensors#copyright
