Itron ERT Model 40G gas meter #170

Closed Adminiuga closed 3 years ago

Adminiuga commented 3 years ago

Hi, Looks like I have an Itron ERT Model 40G gas meter. I don't see any FCC ID on the outside labeling, but I was able to catch it reading which I suspect are happening on demand, as while running the rtl_collect continuously, i'm getting those readings only in the span of a few minutes, roughly every other week. Can anyone confirm those could be configured to broadcast readings only on demand and if there are any pointers on the signal/trigger?

It is pretty likely that your silent meter is operating in "wake-up" mode, which means it will only transmit when asked to by the utility.

Adminiuga commented 3 years ago

Yep, looks so. Just wonder if anyone tried ti reverse the wake-up signal? gegt Since I only get the readings once or twice a month, makes a bit problematic to catch the actual signal.

See this issue for reasons you probably wouldn't want to wake the meter yourself.

That valid concern. Was not expecting the wake up signal be outside of ISM band.
