A user has kindly reported today that TPL Bridge works out of the box with the TP-Link Kasa Smart Plug mini outlet HS105.
TP-Link just announced at CES that they plan to release a software update later this year to provide native HomeKit support which is great news. Until then, TPL Bridge will give you HomeKit support today. No news on HomeKit compatibly for other devices in the Kasa range, so TPL Bridge may still be needed for those.
