Create an offline listener is unncecessary, I think...a phone have access to the cloud, and it's possible to create an AP with it, where to connect the RPI in the car, (or if home, RPI can connect to your wifi) and at the same time, keep it connected to the cloud by SIM card... theorically, should work. I use my phone to share my internet connecion to other devices often. Anyway, you are right, I will test if it's possible or not at home, creating an AP on the phone and connecting the RPI running the server that handle all my devices, and I will try some voice commands to see if it works, as it do with my router.
About this, I read is possible to integrate volumio (not sure about moode) in home assistant... and google assistant or alexa are easy to integrate in HA too...Well, it's time to make some tests...
Thanks for your support, you put some ideas in my mind to follow...
