Wow. Thanks for the through reply. The price is high, as you mention - once we have an established cashflow with industrial clients and proven technology it will be possible to gradually migrate into the much more cost sensitive residential sector. To enter that sector from the get-go seems like a huge mistake to me. Sure, the subscription fee is a showstopper. I'd like to have several levels of subscription: Free: Live data online, 2 days moderate resolution (sample per minute) / 1 week low resolution (sample per 15 minutes) history. Simple embeddable widgets / twitter usage notifications, etc. $6 /mo ($10 NZD): As free, 1 year moderate resolution, 10 years low resolution. Add Webhooks, SMS, email, alarms, budgets, etc. Premium: (this is for industrial, price TBD) 1 month ultra-high resolution (1 second samples), unlimited storage for other data. Most home users would be satisfied by that free option. As for your customers: First Group (price sensitive domestic): I agree. I'm not even attempting to reach this market right now. Second Group (CO^2 sensitive): I think that these users will be most interested in fostering power saving competitions within and between different businesses. Most of them have probably optimised the hell out of their domestic power usage. They might be interested in leasing our system for a month to validate their power saving measures. If they have off-grid power, our solar integration might interest them. Third Group (Early adopters): The device itself isn't that sexy. As you mention, it is the online dashboard that makes it good. To reach this market segment, it is important that we have great integration with a wide range of other tech toys. I'd also like to make it really easy to hack together neat things using our live data via webhooks and the API. I'm looking forward to the linkerati aspect. Hopefully we can foster a situation like Twitter - people linking proudly and prominently to their GridSpy Dashboard to prove their Green/Geek cred. Industrial Environment: Good point about the non-linearities in industrial circuits. Gridspy could be used to hunt down the poor power characteristics that cause industrials to be penalised by the power supplier. Because of our realtime data acquisition, we could highlight the power factor of motors during startup, running or shutdown. This would help electricians locate and fix key power issues. As you mention we could be used to help cut power usage during certain times of day. We could also perform load-shedding - turn off AC while many motors spinning up for instance. The peak power usage during the day needs to be kept down to reduce power cost. Finally alarms and budgets could be used to attract attention to important issues. All in all I'm pretty excited about our opportunities in the industrial sector. I think that the Residential sector is too disinterested and price sensitive to enjoy GridSpy.
