I use a Dome, but like everybody says, they will repeat chimes. Highly annoying but not a lot of great options. I love the flashing light it has to also indicate a chime.
In regards to multi chimes....
I have both the dome and the aeotec 6 and they both suffer the issue if multiple chimes. There is a technical explanation in the forums somewhere as to why But I think it requires either firmware fixes or hub fixes to solve. As a side note I’m not a fan of any of their chime options.
I also have the zooz zse19 and really like it. It’s much bigger and only battery powered but also like the fact that you can load your own sound. I haven’t yet been able to see if it has the multi chime bug as well.
Another option. If you have a tablet running a dashboard with fully kiosk browser, you can also set it up as a chime or tts device. This works really well and if you have a headphone port you can put your own speaker on it.
