Just switched from iris and I never had luck getting my iris ZWave opener to work with my chamberlain opener. I know the device works as I had it working on my detached garage with different brand opener, device will beep but that is it. Ironically enough I bought the opener from Lowe’s.
If your Chamberlain opener is one of the newer models with "Security 2.0" (Wall button has a display) than you will not be able to use a standard "smart garage door opener" with it, you will either need to try the community "Chamberlain MyQ integration app" or look into a "smart opener" like "tailwind" that supports these models.
It is a newer opener but just a simple “door bell” style switch. I will get the model number when I get home.
