I only have one, but it's still working. I'm assuming you're aware of the typical problems people have with these fan controllers: they need a Zigbee repeater fairly close because their radio seems to be weak, and they are prone to becoming unresponsive if not (if you aren't, there are a few threads on the subject). FYI: unfortunately, if the device needs to be reset and rejoined, last time I checked, the child device DNIs are created relative to that of the parent, which may (will?) change if reset and rejoined, so the "old" child devices won't work anymore and you'll have to use the new ones, including plugging them into existing automations where you may have used the old ones.
