When is HomeKit support coming?

I understand ring is owned by Amazon, however they don’t sell mobile phones to my knowledge. Those who run a ring security system, or even just a doorbell camera but don’t have any home smart assistants and run their ring system entirely from their phone could benefit greatly from this. And it’s not like Amazon would be losing customers purchasing Amazon Echo devices as they probably would’ve bought one by now, not that they could take their echo show on the go with them to control their ring system with their voice.
