Feature requist smokealarm and doorbell without camera to ring alarm

Hi Ring, I'm looking for an option to couple a doorbell button to the RING alarm (i do now use a doorcontact for this). Reason is that I don't want a camera on my door but do want to have push messages on my phone. With this i'm also looking for a chime that can be coupled to the alarm (also as extra siren (maybee with a light singal as well). Second request: In Europe there is no option to couple smoke detectors to the RING alarm. For now I use the panicbutton where I modified the internal button and connect it with some electronics to my smoke alarm system. Is there an option to create a inputdevice which accept a signal from a smokealarm (digital or potential free contact)? Best regards, Jeroen
