Ask HN: Need an IoT device that blips or blinks, recommendations?

Hi HN! With my severely bad electronic skills, I am trying to buy an off-the-shelf IoT device that can be beeped once remotely. Basically, imagine was an HTTP/RPC endpoint that I could call to beep this device once. I am trying build a pipeline that would beep the device every time one of my repos get a GitHub star. So it would work like: GitHub WebHooks --> Lambda/Google Cloud Functions --> API --> beep! Any ideas if any off-the-shelf devices on Amazon.com can get me there? I thought of pushing messages to Alexa/Google Home, but that doesn't seem to be a possible action.
