Sure. The electric company rolls trucks to the older meters (known as AMR meters). These trucks have a big radio in them that listens for the meters, which broadcast wirelessly on a spread spectrum frequency. We made some hardware that can listen to your meter at 30 sec intervals and graph your energy use from the resulting data.
- ScottBurson 10y agoAh, okay, I found this: https://en.wikipedia.org/wiki/Automatic_meter_reading https://en.wikipedia.org/wiki/Automatic_meter_reading Looks like there's some variety in how meters broadcast, though. Is there some way to tell by looking at the meter which technique it uses? Do you support both DSSS and FHSS?
- andrewzimmer 10y agoWe're focused on FHSS which covers about 60% of the US (we've gotten 600k reads from about 10 different states so far). DSSS is newer and used by mostly smart meters (ZibBee for example), which have some other blockers like encryption keys. We look for a barcode on the meter to tell if it's FHSS, if you grab our iPhone app it'll walk you through the process.
