Actual Schematic of the WCC (WDCWSLU) Chime Controller

UPDATE: This connection method works! I had to be more patient (not my strong suit) and let the capacitor charge up. It does mention on one of the help posts on the Wyze support page to “wait 20-30 minutes” and also the app on my phone kept popping up with a message that that said “…device is initializing. Try again in 15-20 minutes” or something close to that. I left the unit, WCC and relay all connected on my test bench for over 30 minutes. I was then able to set the “Doorbell Chime Type:” to “digital” and set duration for 1 second (default). When I went back and pushed the button, I heard the local chime from the doorbell and the relay energized for 1 second! Success! So today I will be wiring this all into my front door (replacing the v1) and NuTone IM-4406 Mater Station and IA-29 Chime Module. I plan on putting the WCC and OONO relay in a junction box near the transformer and have one wire run to the doorbell v2 and another run to my IM-4406 Master Station (the one abandoned in place). I will post a picture of the completed junction box as soon as I get it completed.
