$5 DIY Sonoff Universal Chime
cults3d
I was NOT going to pay a 100euro for a Ring Chime ... no way. Way too expensive and only does one thing ... oh, and I'm cheap! I got a Sonoff RE5V1C and an acitive buzzer and made tiny teensy ini mini-usb powered universal Chime. For less than 5 bucks! Not the prettiest, but it also does not take up half the room (wth Ring?). I can now make it beep for whatever I want using HomeAssistant and/or Node Red. The unit runs on a esp8266 so it could also be flashed with EspHome or even custom code.
