After much experimentation I find it the best to setup separate Raspberry PI to run Node Red and talk to Cerbo over DBus TCP and to other things via any other available mechanism, WiFi, Bluetooth, whatever you want…
That way you can easily follow all Cerbo updates without much added customization and have your playground elsewhere…
