Within the ring app there is a toggle to allow the in home chime to be triggered or not. It would be useful to have this control in HA if possible to allow automations to turn on and off the chime. Would be perfect to set up when the baby is sleeping rather than going through several menus inside the Ring app.
Setting in the app is found under device settings → In-home Chime settings. Unsure if this level of control is possible.
Bumping and voting this one. I moved from home bridge to home assistant, and so far, this is the only feature I am missing throughout all my devices. I keep the in-house chimes off from 6am - 8pm since our phones will be on if we are home and don’t want the dogs barking, but now I had to switch it to always off, for now.
Will also look into contributing, but I am not sure how far I can get as a noob 
Leaving a note for myself or anyone else that finds this and wands to make a contribution. I’ve started working on it, but am not totally confident about it yet.
The Ring API project that this integration uses has the functionality in it. the definitions are here. we need to surface existing_doorbell_type and existing_doorbell_type_enabled as well as use async_set_existing_doorbell_type_enabled to turn the in-house chime on and off.
I’m traveling, so it’s made some of my testing a bit harder, so I will likely dive into this in the coming weeks.
