I actually have just around 100. I've been at it for about 3 years in this house and have removed some devices, and then added them back in different locations months or years later, and just plain tried a pretty good number of devices. It seems that if you added and removed a device 200 times, then next time you add it it would be device number 201. In any case, its not as many as it looks.
That being said, I'll order up a second hub.
For sure, I signed up for Protect service pretty much as soon as it launched. I also try to make intermittent backups that I keep on my Synology.
When it comes to dividing up devices between hubs, any recommendations on how to do that? By zone? put the east end of house on 1 hub and the west end on the other? Can 1 hub run automations with devices from both hubs? If traffic on the zwave network is the real problem, can you keep all of your automations on the master hub and just focus on offloading zwave tasks to slave hubs?
You guys sure have given me some more to do projects! I'll get to work on these things and report in. I think i'll have to fish some ethernet cables through the house this weekend to put a new hub or two into the most node rich areas of the house.
