I wanted to see what ideas people had in terms of best architecture using the new Hub Mesh.
Doing some reading and thinking through some of my considerations, I think there are at least 3 main architectures that make the most sense for a 2 node mesh.
- Split devices between the hubs based on physical proximity to hubs, split RM, apps, etc equally
--pros: Maintains at least half of house mostly working if one hub crashes.
--cons: Requires hubs placed at opposite sides of house (maybe running some Ethernet cable) 3rd party apps crashing both hubs. Both hubs potentially slowed by memory leak or performance type issues of apps/RM
- Separate Z-wave and Zigbee hubs - split RM, apps, etc equally
--pros: Maintains some devices working in hub loss event. Minimizes interference between freq.
--cons: Both hubs need to be centrally located, yet somewhat separate. 3rd party apps crashing both hubs. Both hubs potentially slowed by memory leak or performance type issues of apps/RM
- Keep all devices on one hub and apps, rules, most automations on separate hub
--pros: Simple migration from centrally located 1-hub topology. No need for separate cable run to new location for new hub. 'Device' hub will continue to be fast with simple automations even if cloud based apps/services slowing down 'Apps' hub.
--cons: If 'Device' hub goes down, nothing is working
As you can tell, I'm definitely leaning towards architecture 3. In my case my current hub is centrally located with no problems of loss of z-wave/zigbee connectivity due to distance. My main issues are slowdows causing simple automations (motion lighting) to be less functional. Currently I restart my hub about twice a day to refresh. I also would prefer keeping the second hub close to my switch/closet.
