Sorry for the delay. I have upgrades to v5.0.16C(RC1) and Z-wave Firmware at v4.55.
The Doorbell is added and installed correctly now. :) There are 8 'sound switches' detailed in the manual for separate purposes. (Sound Switch 3 is Door Button 1) you can set the volume and default tone from the manual there are 30 preloaded tones. Once installed you can use the doorbell as a responder to scenes so you can use the speaker as a output device for your events and programs. (i.e. play a tone when a door scenes open, or siren in an emergency, trust me 100% volume is LOUD my dog hates me). Of course, the main use would be for the Door Button to set off a chime (normal doorbell operation). That works no problem.
However here is where you might not like it. You currently cannot use it as a scene controller (Trigger a scene when pushed). That being said, you can write a program that checks the value of "current tone". (by matching the tone number number 1-30). So I have my doorbell button 1 set to tone 4. I then have a program that says if sound switch #3's (Button1's) current tone = 4 (meaning it is playing the sound) then run the program 'then' code and when the tone is done (quick play) it will run the 'else' I added a wait in the else so it waits 30 second before running the command. So you can use the button as a "trigger". Now here is a weird part. When push the button right away ISY reports (Main Tab - Sound Switch #3) Default Tone = 4 is playing. But the program with the if clause takes 6-8 seconds to start the program. I am not sure why the delay.
So that is what I have for you or anyone the wants to use the AeoTech Doorbell 6 with an ISY ISY944i ZW+
Please comment if you have any information regarding the delay please let me know.
