I only tried it with one dimmer; thank the lord. I could not get it to work properly (update status on the driver page) when I switched back to the previous driver either. Then, later in the day, it must have started spamming the hub and everything went unresponsive, which I posted here. I disabled the dimmer for now, and will try excluding it, yada yada, before replacing it with a Zigbee dimmer.
