Hi,
I’m new to HA though I’ve been using Telldus .net for a while now and I can dim my switches from their web app and from remotestick on my phone, however I can’t dim my switches from HA, does anyone else have any problems dimming their lights with HA using a Tellstick.net?
Regards,
Keith
The dimming functionality is not implemented. See Telldus Live support for Light component
Have you checked if you can connect to the Tellstick hub directly? https://home-assistant.io/components/light.tellstick/
AFAIK it is not possible to make the Tellstick Net being recognized as a Tellstick duo, and thus you have to use the Telldus Live service.
Until implemented, no dimming is possible for Tellstick Net devices 
Please vote for this feature to be implemented! Telldus Live support for Light component
Is this compatible with the transition keyword?
action: service: light.turn_on entity_id: light.sleeping_room__bed data: transition: 120 brightness: 255
I am trying to do this but it just turns the light on instantly.
