I can […] use 2 way audio to chat to the person at the door.
How did you get this to work with HA? There are a lot of users having issues with 2-way audio on Reolink doorbell, some users stated that only works if the firmware is at a specific version
And
I’m planning to build things to my HA and a 2-way doorbell is on the list, so I did some research and found users having issues with it, could you please show what you did to get it working?
