Kogan have just expanded their Smarter Home product range to includes lights and pugs with energy monitoring. They started with just heaters and look to be adding a whole range of products (including A/C, cameras, doorbells and IR controllers - this is from the add device option in the app).
I bought some of the light bulbs because they are just basic wifi bulbs (no extra hub needed) and they are really reasonably priced - $89 AUD for a 4 pack of coloured bulbs and $69 AUD for a 4 pack of white bulbs.
Their devices are controlled by an app called SmarterHome (https://www.kogan.com/au/smarter-home/) which offers basic functionality.
I would love to see these products integrated into HA.
