They are still discussing it. In fact, just barely in mid-June, the VP of Product told us they are working on offering a “universal chime” that can act as both a speaker/siren and a universal connection for products that don’t have WiFi:
Whenever these release, I will get some. I am hoping they will allow me to connect Bluetooth products like the Lock Bolt or scale or other things to WiFi!!! But I will also use them for the HMS siren and chiming noises throughout my house.
Stay tuned! VP told us they’re working on it!
