&quo...That said I found this on the Blue Line site:<br />"The Sensor does record a running total of the cumulative total, however the time the 2 units are not communicating, and the household usage in that timeframe will determine if cumulative data has been lost. For example, a break in communication for an hour with low usage may mean the total will update correctly when the communications are re-established, but after 3 days and a household that draws many kWh’s per day, will mean that the total will not jump to cover the missed time.<br /><br />Upon reconnection, if the data in the communication break has indeed been lost, the total will simply start counting up again from the last value."<br /><br />So there may or may not be a "pulse" between the RF receiver and the micro.Anonymoushttps://www.blogger.com/profile/12753067594302662355noreply@blogger.comtag:blogger.com,1999:blog-2636816351347968196.post-28576551007359120442013-06-05T09:33:32.996-05:002013-06-05T09:33:32.996-05:00Black & Decker as well as Blue Line offer mete...Black & Decker as well as Blue Line offer meter reading devices that monitor the IR emitter on the meter. Rather than trying to decode the meter's RF transmission (a worthwhile poject in and by itself), if all you want is to get the meter reading here is an idea...<br /><br />The base/inside unit is a receiver and I suspect that somewhere on the base unit's board there is a pulse generated each time the receiver receives a transmission. Someone skilled in the art (I am not) could likely find that point between the RF receiver and the micro that counts, process and displays the info. Thus you can use that point as an input to another micro such as the Arduino.<br /><br />The B&D and Blue Line units show up on eBay for mid $30 and upwards and are a cost effective way into personal meter reading.<br /><br />If someone finds that point ... let us know where it is.Anonymoushttps://www.blogger.com/profile/12753067594302662355noreply@blogger.comtag:blogger.com,1999:blog-2636816351347968196.post-73444728279671830892013-05-20T02:15:15.075-05:002013-05-20T02:15:15.075-05:00I was just checking in to see if you had had a cha...I was just checking in to see if you had had a chance to further research reading the Itron's ERT using rtl-sdr.

After one month, the CENTRON R300 meters proved their ability to measure energy usage not measured by the electromechanical meters. This accuracy showed two kilowatt hours more than the electromechanical meters. That does not sound like much of a difference, but when it is multiplied by 10,000 end points, it adds up,” said Hastings."</i><br /><br />Positively Orwellian. Because these black boxes registered consistently higher readings than electromechanical meters, they were "more accurate." What utility company wouldn't jump for joy at that figure. This is a blatant "wink and a nod" to utilities to not worry - they'll get their investment back sooner than they thought.congressivehttps://www.blogger.com/profile/10790894644594724263noreply@blogger.comtag:blogger.com,1999:blog-2636816351347968196.post-51763725396138939292012-02-27T23:42:02.946-06:002012-02-27T23:42:02.946-06:00This comment has been removed by a blog administrator.prince hotel honoluluhttp://www.honoluluhotelsadvisor.com/noreply@blogger.comtag:blogger.com,1999:blog-2636816351347968196.post-80423034787098230132012-01-12T23:50:26.998-06:002012-01-12T23:50:26.998-06:00Wow that electric meter reader has a lot of uses. ...Wow that electric meter reader has a lot of uses.

There is not any encryption, as these systems are one way data. The meter is not listening and won't accept commands from you.
