Two hubs one network

Why Hubitat Elevation
1

Hi, all. I have two buildings on the property that share one wifi network over ethernet. What I'd LIKE to do is be able to control things in both buildings together, things like using Alexa for the "goodnight" function of locking all of the doors, turning of certain lights, setting back thermostats, etc. I currently do all of these things in the main house now, and just want to extend things to the outbuilding. The zwave does not reach the second house at all, so I'm looking into how to do it.

If I install a second hub on the same internet network, will I be able to accomplish this? Any pitfalls, gotchas, etc?

Thank you!

Stephen.

Yes you can do this, it’s precisely what the Hub Mesh feature is intended for:

If you have network in the out/2nd building/house then you can use hub mesh to connect 2 hubs and share/control devices.

That is exactly what I do, main house hub and 2nd hub for the mini house. They are mostly independent but I use HubMesh for setting modes (mostly for the away function), monitoring, thermostat setting based on presence and/or occupancy of the mini house, synching outside lights, PIN code management of the electronic lock, etc.

I have 5 production hubs located in 5 separate buildings all running independently with the exception of centralized rules managing some devices such as locks thermostats and battery monitoring where the locks and other devices are federated into the main house hub using hub mesh.
Automations specific to each building are run on each local hub, and any global rules on the main house hub.
I use lux and temperature readings from a motion sensor outside on the main house to manage lighting levels and thermostat mode management.
I probably have 30 devices meshed between these hubs, some devices I bring into the main hub just to have available in the mobile app

I might be of the dissenting view on this after having started down the path of a tight meshing and interdependence between hubs ...and then reducing that interdependence to a more informational relationship than actionable.

I have one C5 hub starting to exhibit lockups after years of incredible reliability in extreme conditions. I suspect it's the wall wart but we'll see. But my point is... I'm very glad to not have one environment handicapped by dependencies on the other.

That is to say, you can do some really cool stuff but just be thinking...if I lose one of those hubs how does that impact what I see or have done at the other.
