they changed the frequency from 433 to 900 MHz, supposedly longer reach it's obvious they didn't want 3rd party chimes.. this wouldn't be so bad, i mean they have their right to close their system if they want, but they don't offer additional chimes.. if you want one you pretty much have to purchase a new doorbellWonder if there is something ReoLink did to the newer DBs to stop third party Chimes
oh and, if you want to buy another doorbell to have a second chime, make sure you buy with the right chime either v1 or V2.
