Correct yaml for multiple tradfri gateways?

I have this yaml in my config:

tradfri:
  host: 1.2.3.4
  host: 5.6.7.8

Only first host is detected. And log tells me:

configuration.yaml contains duplicate key “host”.

This wont work too:

tradfri_1:
  host: 1.2.3.4

tradfri_2:
  host: 1.2.3.4
  host: 5.6.7.8

I am lost…

Is no one using more than one gateway?

How many lights do you have that you need two gateways? Im using 1 so i dont know what to do.

I have three lights each gateway, each gateway on a different floor.

did you got it working with homeassistant?

Nah, no success on my side. Problem is the pytradfri component at the moment. Check here to get some info about the issue:

ggravlingen and Hate-Usernames are on it. But we have to be patient with this situation. The work is done in free time.

Perhaps you can help by coding some parts? I can only help by debugging and testin… I’m no coder…
