Hello,
Thanks to the information provided in https://community.home-assistant.io/t/wip-doordroid-smart-doorbell-with-lovelace-integration-video-and-2-way-audio-without-cloud/118099 and additional support from @rdehuyss I have something that works !! My GDS 3710 calls my Android tablet and I can talk using webrtc. I am still working on some changes in doordroid.js provided by rdehuyss to improve the card. With my abyssal ignorance of javascript, my “improvements” are very likely offences to true JS developers. However, at least it starts doing what I want to do. I am still working on it but I should be able to post my design in a week or two.
