Either let people toggle on/off a temperate graph overlay on their energy usage chart...

Or run a regression on energy usage and temperature and tell them how much of their energy seems to be temperature dependent.

send wattvision device data to pvoutput so it can be compared with others

I had to open 802.11b just for WattVision. The sensor should support 802.11g or n... no other device in my home is 802.11b. That's just silly.

Is the gateway able to support several sensors? The obvious one would be to hook it up to the gas meter (though that seems difficult, mechanically) or just to monitor the valve on the boiler to log how much the heater is running.

Is there an application for uploading the data from a CurrentCost power meter using the USB connection?

Comprehensive pricing data would allow you to automate and individualize the price per KwH for customers in you apps

I would find a report by a date range available on the website very helpful. More helpful that strictly monthly I'm sure very few have electric bills that have billing dates that fall on month end.

The current uservoice forum is a little cumbersome, at least switch to something like getsatisfaction

It would be good to display the anual prediction of energy or the actual anual energy consuption.

Several wifi enabled thermostats on the market today could be configured to display the information from your sensor so you could see it in real time in the house without having to use a computer or smartphone.
