I decided to buy a C7 to upgrade my C5 since my z-wave network hasn't been very reliable.
I upgraded the firmware on the C5, then did a backup/restore onto the C7 in order to maintain the devices and rules. Next, I tried excluding and removing the z-wave devices from the C5.
I was of the understanding that the C7 would recognize a device based on its z-wave address and allow it to be replaced within the devices. Unfortunately I haven't been able to get this to work. Adding a device now has had all sorts of wonky results - as if the process is suffering form a one-off error. Removing and re-adding one of the z-wave thermostats has resulted in child devices that belong to different device!
Is there a proper way to do/fix this?
