Tellstick binding maintance

Is anyone doing some upgrades on Tellstick binding?
I think Telldus is unic as a low price stand alone building were you want some simple temp/heat.

But it could also be used as a good energy system as all z-wave decives with energy consumption also works. Only problem is that energy data will not be sent to Openhab as it just support sensors as temp/humidity as i can see it.
