Platform not found: climate.yr EQ3BT


I am trying to get my Bluetooth radiator valves working in HASSIO.
I am putting this im my configuration.yaml:

    platform: eq3btsmart
        mac: 'AB:CD:EF:GH:IJ:KL'

When i let HASSIO check the configuration i am getting this error:

Configuration invalid
Platform not found: climate.yr

How can i solve this issue? I am following this instruction:

I am running the latest version of HASSIO, 64-BIT on a Raspberry Pi 3B+

This is my first post on this forum, if you need any more info please let me know.

The yaml seems to be wrongly formatted (missing -). Look at the linked example.
