Re: got my smart meter today

said by jchambers28:

How can i tell how many watts I am pulling from the poco? I am trying to figure out how many watts my central air conditioner uses.

Once the meter begins scrolling it will display a number of parameters, the one you want to watch out for is the number of kW being consumed.




Once you determine your baseline kW being consumed with the A/C off politely ask everyone else in the home to avoid using high wattage devices during the test and once that request is met turn on the A/C and take a new reading of the kW being consumed, the difference between the baseline and the current reading is youre A/C startup wattage consumption, take a fifteen minute or so break and re-read the meter and that difference is going to be real close to your average A/C wattage consumption.

it's scrolling now closed and KWH. But no load data. I have to wait 3 days before setting up a account to look at usage tools at poco site:(. Too bad these do prevision as fast as cable boxes.

Any way to tell if this meter is provisioned.

Looks like your I-210+c is "fully loaded" with almost all optional features installed (except K2). We have the I-210+ (no c) and on ours the only feature codes are O, V2, F2, J2, U2.

Does anyone know the meaning of all the different factory feature codes ?
Most of the following are from GE publications but some are from similar discussions on the Internet:
O (I-210, I-210+) or A2 (I-210+c) = AMR Communications (allows an option board / plug in module to communicate with the meter)
E2 (I-210+c) = Event Log (allows the meter to record up to 200 events)
F2 = Demand limit
J2 = Emergency Load Reduction (two common 120V legs, no 240V)
K2 = Ability to measure kVA/h or kvar/h in addition to kW/h
N2 = Demand based metering/billing
Q2 = Power Quality monitoring
R2 = Load profile recording
S2 = Ability for AMR calculated demand value to be displayed
T2 = Time-Of-Use metering
U2 = Disconnect switch
V2 (I-210+) = Voltage Event Monitor (counts over and under voltage events)
Many options are only available on the I-210+c.

As for the storage of usage information, you need to distinguish between the actual electric meter made by GE and the smart meter add-on (made by Silver Spring Networks in our case).

The GE meter itself only stores total power but no usage history about when you consumed that power. However this total consumption information is retained even if the meter is disconnected from power for extended periods of time without any battery.

The smart meter add-ons (there are different kinds and their programming can be changed) do have sufficient memory to store meter readings without having to transmit those to the utility immediately. How much usage history is being retained inside the smart meter memory depends on how often it reads the meter (currently it is hourly for us here) and how often it transmits that data to the utility (currently once a day). If I remember a presentation by PG&E correctly they like to keep the meter reading and the reporting intervals set to values that prevents loss of information even if the meter is unable to report back to the utility for one whole week. The smart meter module will loose its stored values with loss of power but it does have a capacitor to provide power for a dying gasp transmission.

The meter display rotates through several displays, some of which are optionally and may be skipped if they don't apply (such as separate consumption counters for Time-of-Use, separate counters for received and delivered energy for grid-tie systems).

In your meter it appears that the upper line is used to show total kWh alternating with the status of the disconnect switch (closed) while the smaller lower line shows current load in kW (perhaps other values too?).
In our case the upper line shows total kWh alternating with display test (all 8's) and the lower line alternates between load in kW, line voltage and the status of the AMR communication module "Adl" followed by "on" (disconnect switch status ?).
Both meters have a display of 3 bars that are supposed to simulate the red or black marking on the rotating disc in old electro-mechanical meters.

01 = Current meter read.
The corresponding number indicates your kWh usage

For the curious, even if your utility company hasn't directly provided this information, there is a TON of stuff about various smart meters out on the internet now, if you know your manufacturer and model - marketing info, technical info, news reports, and so on. Also plenty of info on how secure (or not secure) these are, if you are concerned about this.

Smart meter plus
Got my smart meter a while ago. The city-owned power company ran fiber to its meters and sells cable/internet/phone service through it, busting the former (horrible) Comcast/ATT duopoly. They're making a profit too.

I have a synchronous 100 MPS connection and HD cable for $200/mo. To the left in the picture is the disused phone connection, and out of frame is the old Comcast box.

TVA and epb, Viva la socialisme!

I "lost" my Smart meter after I had a solar interconnect system installed.

During testing of the solar system, the Smart meter display showed power delivered and supplied. When I checked the stats online, I could clearly see when the solar system was generating power, reducing consumption initially, then going negative during the sunnier part of the day.

Then PG&E came out, removed the Smart meter and installed a mechanical meter that the guy said was required for interconnected systems. I lost all of that online data. Bummer.

So it turns out the "smart" meter was not so smart after all. All that technology and it can't do net metering?

Sounds like the meter was too smart for the good of the customer. No need to pay peak rate for exported energy when all one has to do is take away the proof it was really generated during peak hours.

It's interesting that the POCO is equipping smart meters with the remote disconnect feature for typical accounts. Locally, the POCO only uses meters with remote disconnect on "problem" accounts and locations which prove to be high turn-over. The thought of widespread use of a 200A switch buried in the From 2S footprint is kind of spooky. Won't be long before smokes are required above the meter pan.

I wonder if the switch is "fail open" on power failures? That would shed a lot of load when restoring power in high usage times. After the power is restored the POCO could then reconnect a few at a time.

It would normally be closed with power on

Glad to see that this is working out for you folks in Chattanooga. We never got the chance to do it here in Memphis, thanks to Time-Warner's legal shenanigans; it cost them big, too, though - TW is gone now with Comcast in its place, and a huge number of folks around here have switched over to satellite or Uverse.

But I've read some complaints here on the forums about EPB not being at all friendly towards companies that want to piggy-back on their fiber, which I find a bit surprising. I can understand a need maybe to do this in the early days - a temporary pseudo-monopoly in order to guarantee payback for the capital expenditure of the fiber installation - but if this turns into a long-term thing then I (as a consumer) would be most displeased.

We should probably clarify the sequence of events...

In a power failure, the switch should close, and remain closed until the next shed event is called by the smart meter.

Neither

It is a bistable (latching) relay. It just requires a momentary pulse to turn it either on or off and doesn't require any power at all to maintain the on or off state.

Don't feel too bad. We're two years into a three-year Smart Meter pilot program here in Memphis, and MLGW still hasn't gotten their act together fully. Things mostly work right now, though.

That's because PG&E's IT people are too stupid to figure out how to do net-metering with the smart-meter data stream. My PV grid-tie install required removing the (recently installed) smart meter and replacing it with an electronic digital meter which records usage for the different TOU buckets and requires a meter reader to come out.

The stupid thing is even pre-programmed with obsolete daylight savings time start and stop dates. To cope with that, PG&E put the old dates in the tariff!

Supposedly, PG&E is getting close to being able to do TOU net-metering with smart meters.
