Poking around Shodan more, found a few Powerhawk 6320 smart meters that have a web page. No authentication required and it gives up some good information on the device!
Vendor: Triacta (www.triacta.com)
Product: Powerhawk 6320 Smart Meter
It discloses a phone number, alternate phone number, username (email address), FTP username, internal IP address and detailed information about the device.
I don’t know if smart meters are considered SCADA but I found it under related searches in Shodan.
