I’m new to this … I was searching online for a wireless device with prerecorded dog barking sounds that I could plug into an outlet in my garage and trigger with IFTTT whenever certain Z-Wave motion detection occured within my Ring Alarm.
I didn’t find such an item.
Now I’m wondering if I could use Home Assistant to do the same thing, perhaps by sending a sound file to a Google Home Mini speaker.
I’m open to any suggestions!
that should be possible. Just find an dogbark mp3 and send it to the speaker should be quiet easy.
I do something similar, but with Android tablet in one room, and with a speaker attached to the HA server in another room. I’m sending an mp3 of a train station announce ding-dong before a voice message from TTS.
Just I do not use Google speakers, so I can’t give you exact steps. But is is for sure doable 
Hello,
buy a lumi-gateway-v3_miio and integrate in HA : then : with an automation
ID for barking dog is 8 if i well remember…
there is a long long long thread here : https://community.home-assistant.io/t/not-able-to-get-xiaomi-gateway-key/61795/159
choose the MIIO version, not AQARA and V3 is easier to integrate in HA.
