I use the Eaton RF9600 series devices throughout my home. @thebearmay is correct the RF9617 is not intended to perform any physical control. And @JasonJoel is also correct. You have to get all of your devices paired to HE first.
To set up 3 and 4+ way control you either have to write rules (Simple Automation or Rule Manager, etc.) or setup direct associations between the devices. I prefer the latter. I believe it makes my automation system more resilient to failures. In the event my HE is offline my 3 and 4-way switches still function. Setting an association gives a device permission to send a limited set of commands to the target device.
Here is a post of mine on this very subject. It isnāt difficult. It just requires careful planning. Eaton devices use the following association groups:
Group 1 - Lifeline.
Group 2 - ON/OFF
Group 3 - Dim Up/Down. Only on the 9640 and 9642
Do not use Group 1. We can have an esoteric discussion about why another time.
