Tradfri: Multiple gateways

Configuration
1

I’m trying to get HASS working with a second Tradfri gateway (they are in different locations). It seems that the gateway is discovered on connected, but I can’t see any lights connected to this gateway.
Is this a limitation of the Tradfri component? Any chance this can be fixed?

I also see this in the log file:

When you say different locations do you mean different buildings? If not trådfri creates a mesh network so placing additional lamps between the locations should mesh the network so you only need one hub. (each lamp can forward the signal)

If that is no option you could try something like tradfri-mqtt and use that for the second gateway. (I have not tried it my self as I only have one gateway)

I can’t use a single gateway as the lamps are in different locations. Having workaround like MQTT or a second HA instance might work, but will complicate things a lot. Therefore, I would like to see HASS working with multiple gateways.

Did you ever get a working setup with multiple tradfri gateways? Could you post the yaml part of your tradfri config? Thank you!

Never got it running with multiple gateways :frowning:
