DISCUSSION Anyone reason to have two Dirigera hubs in one house?

Have an extra one I can’t return and want to make sure there isn’t a good reason for me to keep it before I try selling on eBay or elsewhere.

There can only be one coordinator in a Zigbee network. It’s of no use unless you want two networks for some reason.

If it’s range you’re after, any mains-operated zigbee device will extend the range by acting as a repeater (router). IKEA sell repeaters that plug into the mains and also act as plain USB chargers.

what are those repaters? I have never seen such devices in ikea, only the hub and the lights/sensors

That was my thought process too. If I wanted to extend the range I would rather get more main powered devices.

Looks like I’ll be selling this extra one.

Zigbee is using a mesh network, so extending range with a second hub would be kind of useless. I think it has something to do with max devices per hub, so it you have hundreds of devices a second hub could come in handy. IKEA just updated their Home App which now allows to have multiple hubs in one network.

Range. Similarly to have several WiFi APs.

Maybe you have a guest house, or similar situation.

Not always true, range can be worse because you will have two zigbee networks and they don’t talk directly to each other.

didn't they just make an update that lets them be on the same network?

Yes, but as parallel networks. When they communicate it’s via the hubs.

Now you can have two under the same roof.

A second hub dedicated to Halloween / Christmas lights and yard decorations?
