@Fearny Yes, I did see that Amazon listing of the Byron 776, but the minimum was a quantity of 3, so weird! After some more digging and research, I saw this listing: Greenbrook DHT01A-C Door Chime, Transformer & Push Kit. This is is in the compatible list, so let me know what you think of it! It is indeed harder to find one that has the transformer built in, so feel free to do some more research with the other chimes listed as compatible.
