Balboa GL ML Spa Control
While there is the excellent https://github.com/ccutrer/balboa_worldwide_app project that handled the new WiFi capable BP range of controllers, their project is NOT compatible with the older GL/EL range such as the GL2000, GL2001 or EL2000 - This one is.
The aim of this project is to achieve similar Home Assistant integration as the app from ccutrer - we are about 95% of the way there
