Reading this thread with interest as I'd like to extend coverage outside my house to the garden/shed and the signal from the current hub in the house isn't reaching.
Seems like my options are second hub or signal repeaters. One thing I'm hoping someone can help clarify is what are the disadvantages of going with a second hub option? (other than it likely being more expensive)
Possibly less potential interference especially If the hubs are too close - with Zigbee you can change the channel though. However repeaters do add complexity to the routing. A multi-hub setup is more complex on the rules and config side of things.
I agree but it is still (a bit) more complex than just a single hub setup and to your point definitely more difficult (but doable) if not on the same subnet.
As a happy multi-hub user and recommender I was kind of reaching for disadvantages..
I find that repeaters can make the system more robust and reliable, and so I use them with two of my three hubs on our property (which has three buildings). BTW, while I formerly used Aeotec gen 6 repeaters, I've now switched to Ring range extenders because they can report power out/restored, which is handy.
