Digital Electric Meter
17 Dec 2013 -Got this email from PG&E today, in response to my query to see why I could not see any on line indication that there was a smart meter here.
"We sincerely apologize; however, at this time your meter is not being read remotely. Pacific Gas and Electric Company will establish a remote connection with your meter once the SmartMeter Network is in place. This usually takes 60 to 90 days. Keep your eyes open for communications from Pacific Gas and Electric Company that will help you take advantage of this new technology."
I thought they would not install a Smartmeter if there was no way for it to communicate in the direction of downtown, but they did. I'm guessing that once they've installed a bunch of them the next step will to make a connection diagram, i.e. have a computer in a vehicle drive around and query meters and see what other meters they can talk to. This would be needed to determine how many and where to install pole mounted units to allow all the meters in this area to communicate with the rest of the system.
I'm guessing that the guy who used to read my meter manually now can just drive down the street and probably not even slow down to read the meter.
meter reads: 1178. Last month usage was 652 kWh, but that last couple of weeks has been the coldest in the past 20 years. There is snow on the ground that's over a week old, that's never happened before.
Installed 16 Nov 2013 (Saturday). If I refused the installation there would be a one time charge like $50 and a monthly charge of $10.
The SmartMeters have a wireless module, typically made by Silver Springs Networks (Wiki), that receives and transmits in both the:
902 to 928 MHz ISM band (peak power out 1.5 to 2.5 Watts) and in the (for meter to meter mesh networks)
2.40 to 2.45 GHz Wifi band (peak power out about 0.1 to 0.2 Watts). (for the HAN mesh network)
Note both these bands are in the Industrial, Scientific & Medical (ISM) frequency allocations (Wiki).
My guess is that the Wifi is to support both the Home Area Network (Wiki).
It's not clear which frequency my meter is using. As far as I can tell the meter transmits once each 15 minutes and with a duty cycle that's way below 1 percent so it's not an easy thing to catch it transmitting.
Installation by Wellington Energy (see their web page for the hand held optical interface test set).
If you know the name of the test set let me know. It's something like TruGPSE01
26 Dec 2013 - A technician came to confirm that the meter was provisioned correctly. He said they are doing that to some percent of all Smartmeters that were installed, but it also may be related to my asking PG&E why it wasn't working.
It's possible that the WiFi radio is for ZigBee (Wiki). If that's the case it would be for the HAN.
The technician who installed the smart meter had a hand holdable test instrument on his tool belt. It had two cylindrical protrusions which I'm guessing are an ANSI C12.18 Type 2 Optical Port. (Fig 4)
This my works with the two horizontal dots just below the lower right corner of the LCD. The left (darker) is the IR LED and the right (clear) one is the photo transistor
One IR LED pulse for each Kt (1.0 Wh in this case) in calibration mode. Each pulse is about 25 ms wide.
The PG&E My Energy page is not updated to show any SmartMeter data until a full billing cycle after the installation (about 30 days).

or about 300 kWh per month.
The appearance of an analog electric meter is the same when the power is off and when the power is on if there is no load or a small load. That's to say if the disk is moving very slowly it would be hard to tell if PG7E was on or off.

Although the smart electric meter was installed in Nov 2013, it was not until Jan 2015 that it worked. The problem was the mesh network could not reach to the collection center. To fix that PG&E installed a repeater on a power pole on a ridge line that has a very long line of sight.
Since PG&E already has a center tapped 240 VAC transformer on the pole (120-0-120) they wired up the 120 VAC power to the repeater directly to the transformer.

The idea is to have various appliances connected to a network
including the smart utility meters so that they can be turned on
remotely in such a way as to use energy when it's not in demand.
This network will not be a normal home WiFi type network because each appliance needs it's own URL and there are not enough of them. But it can operate using WiFi protocol.

A friend's meter.
This is a Badger-Meter, Recordall Transmitter Register Model 25 for 5/8" or 3/4" lines. Reads in Gallons. The transmitter is marked Orion.
Note: there are 4 digits with white background and 3 digits with black background. The rightmost digit is the 10 gallon test circle so does not move.
That leaves 4 + 2 = 6 digits that are live meaning the maximum reading is 9,999,999 or 10 million gallons.
The ideal location for the Orion RF (902 - 915 MHz ISM Wiki) transmitter would be in the lid of the utility box rather than below it for better transmit range.
Badger-Meter also makes an In Home Display that might work with this meter. That would be great for detecting leaks. But that might require repositioning the Orion transmitter so a stronger signal could get to the house? It turns out that the In Home Display only works if the utility company is using a Wi-Fi network to read the meters (i.e. if there's a Wi-Fi signal to feed to In Home Display. But Millview Water has not installed the smart meters with the antennas above ground and has not built in relay infrastructure needed, the meter reader still needs to get within a few yards of the meter in order for his laptop to get the wireless signal.).
The meter uses a piezo spark generator to send a high voltage pulse to the Orion transmitter. That may be it's source of power or it may have a long life battery?

The water bill was way too high so looking for a leak.
Here's a plot supplied by the water company:
My interpretation of the above plot:The spikes are the irrigation timers because those are set to open once every other day for an hour.
The spikes appear to alternate where one is high the next is lower the next is higher and so on.
These spikes are mostly over 170 gallons and the time between the high and high (or low and low) is every other day, the same as the timer programming.
That amounts to over 5,000 gallons in a month, far exceeding normal total water usage, so a major problem.
Although the actual number of gallons varies a little that's probably due to changes in water pressure.
So there's two different irrigation circuits that each have a leak.
The drip irrigation emitters are about 1 gallon/hour and the timers are set to be on for one hour every other day.
A typical drip string has maybe 30 emitters, or should use 30 gallons in the hour and do that once every other day, but the actual usage is 4 or 5 times too high.
There are two kinds of problems with drip: First the end of the 5/8" tube opens or second, the emitter or 1/4" line opens. Since there are a lot of the 1/4" emitters and lines these easily get broken. Since there was a deer (although a fence is supposed to keep them out) in the exact place the emitters are located, i.e. at the Rose bushes, it's probable that a deer has broken many of the 1/4" lines.
Along the bottom there's a pedestal keeping the usage from going to zero and these are constant leaks.
These are the classical leaks, things like a toilet that never stops running, a faucet that always is dripping, a garden hose on all the time, etc.
I think these small leaks are what's keeping the curves from actually touching the zero use line, but instead being a few gallons above it.
On very hot days (the plot includes many days that are in the area of 100 to 110 deg F) the auto fill for a swimming pool will be adding water with a long time constant, i.e. it may take many days to make up the evaporation since the valve is identical to those used to fill toilet tanks.
This may explain the pedestals.
A rough estimate for normal evaporation would be 1/4" per day. If the pool was 16' x 40' that's 640 square feet times 1/48' of evaporation is 13.3 cu ft or 100 gallons/day.
If the meter sample rate is once peer hour then 4 gallons/hour would account for evaporation.
It turns out that one drip irrigation line uses 10 gallons in 2-1/2 minutes and a different line uses 10 gallons in 3-1/2 minutes, this is consistent with the spikes on the plot.
This brings up the idea that while drip irrigation conserves water when the system is new, it can waste more water than it saves when something goes wrong.
I've experienced a couple of occasions where the end stop on a 1/2' or 5/8" line opened up, wasting a lot of water. If 1/8" line is used to feed an emitter it's very common for the line to get pulled out of the main line by an animal. It's also common for an emitter to break creating a water fountain (if it's pointing up) but if it's pointing any other direction you don't see that there's a problem. So for the most reliable drip irrigation system only use large (1/2" or 5/8" line) and only install the emitters pointing up so you can see when there's a leak. Do NOT bury the system since that will hide problems.
Because my friend has strange numbers on her bill, I checked my bill and for Aug 2014 it shows:
Last year 23
This year 3355
But there are no units of measure.
I looked at my water meter and it's been changed to a smart meter and they never told me they did that.
The radio transponder is made my American Meter Co.
Analog Water Meter
Analog water meter reads in cubic feet.
Notice the 4 white background digits are hundreds of cubic feet (748 gal/unit)
These are the units on my old water bills.
The rate in 2008 was $1.29/100cu ft.
There are other items on the bill that are fixed amounts related to the meter and cost of capital.
In 2014 the rate is $0.00192 per gallon
The old rate $1.29/100cu is equivalent to $1.29/748 gal or $0.001725/gal
So the new rate about 11% higher.
Reading shown is:
1057|780|1 (format: WWWW|BB|P)
which is 105,778 Gallons since the meter was at zero.
If the typical monthly usage was 3355 gallons the meter was installed about 35 months ago,
or October 2011 is when it was installed.
Note the new meter reads in gallons and the prior analog meter read in hundreds of cubic feet.
The difference is the new meter reads 748 times higher numbers.
That's why the new meter has 4 digits with a white background,
i.e. the units on the white background are hundreds of gallons.
The billing rate needs to change to account for the change in units and that in turn depends on
how the meter is being read.
My current bill has the numbers for previous and present all jammed together like this:
00105347001056828 which is a 17 digit number not easy to divide into two numbers.
The Model 25 has 4 white digits, 2 black digits that change and the pointer which takes 10 gallons to make a full circle. So my readings are as shown below.
WWWW is the white background, BB is the black background and P is the pointer.
Previous: 1053|47|0 Gallons
Present: 1056|82|8 Gallons
Difference: 3358 Gallons in 30 days or 111 Gal/day. ($ 6.44 for the water)
The bill shows a difference of 3355 Gallons, why?
The rate is $0.00192 per gallon, or 0.192 cents per gallon, or about 20 cents per hundred gallons.

An empty tank is one of the problems with having propane for heating a house. With the cold snap we are having in Jan 2023 the tank can run out if the local company does not drive by and check the level.
One way that should help is to add a Cell Phone connected tank monitor, like those made by Otodata. But even this can fail resulting in a empty tank. If the delivery man arrives and the tank is empty a pressure/leak test is mandatory. The gas will not be turned on after the tank passes the test and is filled because all the pilot lights will need to be relighted. If you are not home when the propane is delivered the tank may be full but the gas turned off at the tank. This is not a problem if you do not have any pilot lights or have automatic pilot lights, but if you have old fashioned pilot lights they need to be manually lit.
PS Another problem with propane is using it for an emergency generator. When the tank runs dry in a emergency it can take months to get more propane. Even now (Jan 2023) when we hare having an extreme cold snap the propane companies are rationing how much they pump to keep all their customers with some propane.
The Nee-Vo App or an app customized for your propane provider, like FerrellFill (Google Play or App Store)can be used.
The App also has provisions for Min and Max Level Alerts as well as Notification when tank filled. A running plot can also be seen (center icon at bottom).
Fig 3 Three ranges:
0 to 25% in the red - need or order more
30 to 70% direct reading
72 to 94% the amount depends on the temperature.
The Nee-vo app is on the Google Play & App Store. Fill out the form. When adding your tank the 9 character code is printed in the upper right of the label. Use upper case without any dashes.
If you have Ferrell Gas you can use the Ferrellfill app. BUT . . .
as of March 2023, maybe because of the unseasonable cold, they are not refilling tanks around 20%, but rather letting the tank get very low (mine is not at 7%). I tried to use the call customer service part of the Ferrellfill app and it did NOT work. This is because my land line phone is registered to my account which requires going through a qualification round of questions then being transferred to a "customer service professional". But instead of that was transferred to the que waiting for a "customer service professional". But . . . the que is screened for incoming phone numbers that are not associated with current accounts, so I got transferred to the qualification round of questions. As you can see this is an endless loop going nowhere.
I've been told that if you wait for all of the phone options the last one is to speak to a human, so DO NOT ANSWER the phone tree questions honestly, but rather try pressing 0 or waiting for that last option.
