Until smart meters become a reality then reading gas consumption is a problem. Somehow a way of reading mechanical numerals and/or a rotating pointer had to be found. Previously, I'd seen discussion on the CurrentCost forum but drew the conclusion it was mostly work in progress. A search of the web revealed a device for reading the meter via the pointer and much more. In brief a wealth of technology was found by the name of Zigbee, Xbee, Arduino to name a few. These encompass both commercial and amateur solutions for monitoring and control. More research on this to come.
