Wait — California smart meters do have problems

By | September 8, 2010, 11:30 PM PDT

Remember how an independent investigator said last week that the millions of smart meters being installed across Northern California by Pacific Gas & Electric were not malfunctioning and overcharging customers, even though a lawsuit against PG&E and over 1,300 customers claimed they were?

Now the San Jose Mercury News says it’s collected dozens of complaints on its Action Line from readers who claim that the wireless smart meters interfere with their household electronics — cordless phones, crib monitors, patio speakers, wireless headsets and microphones, home security systems, motion detectors and remote-controlled garage doors — as the meters transmit their power data back to the mother ship.

PG&E, which was dinged for poor customer service, told the newspaper that the problems are not with the smart meters, but with all the other wireless equipment their customers have. Here, a PG&E spokesman advises one customer to get a refund on the baby monitor:

“We are sorry the customer encountered this inconvenience. The SmartMeter device meets all Federal Communications Commission standards, so in cases like this, the baby monitor wasn’t built to a standard where it would not receive interference from legally transmitted equipment like a SmartMeter meter. It is likely that the replacement monitor was designed so it would not receive interference from legally transmitting equipment, which is why it is no longer experiencing interference. This reader might want to seek a refund from the store or maker of the first monitor she purchased.”

The investigator, Structure, did say in its report that no new issues had cropped up with the meters — PG&E was aware of this one already.

My prediction? Watch for a lot more conflicts like this before smart meters are accepted without questions by the public.

RE: Wait - California smart meters do have problems
Some smart meters can also speed up some electronic (non motor) clocks by injecting extra pulses into the line. Mine did. I have a scope image of the pulses.

RE: Wait - California smart meters do have problems
If a smart meter is inducing spikes into the mains at a voltage which can cause a line-synchronized clock to mis-count then there is something seriously wrong. Generating that sort of signal amplitude is not a trivial task and circuitry able to do it is unlikely to exist in the meter. It seems more likely that the clock itself is not using proper signal conditioning when deriving its synchronization pulses. A well-designed sync circuit will be using a PLL constrained to operate at the line voltage plus/minus a few Hz and will reject zero-crossing noise entirely. Or it will respond only to peak signals of sufficient width to ensure that line noise is not counted -- otherwise any appliance with a universal motor will scramble the time instantly with its brush arcing.

As for interference with RF devices, if the meters have been tested and certified to meet all applicable standards then rejecting interference is up to the rest of the world. A lot of really crappy equipment exists out there with old equipment being far worse than new. Standards have changed and old equipment, if it even met applicable standards when it was designed, will not necessarily be immune from interference with new devices working on different bands and different modulation techniques. That $20 baby monitor bought from Wallymart in 1999 did not have to contend with 5gHz digital transmissions right next door.

Probably 30 years back a baby monitor (noise only type) interfered
with a local electrical utility FM system used by the work trucks.
The solution was not to replace the baby monitor (too cheap of a
solution), instead they changed the main transmitters for the trucks.

RE: Wait - California smart meters do have problems
Typical corporate response when something of theirs goes wrong. It's not us, it's them! There aren't any problems, and if there are, the customer should solve it!

Guess what PG&E? Your ******** has lost you a lot of customers. You lost me when we had rolling blackouts (thanks to Enron) and you refused to install weather stripping, even though I qualified. Keep it up, and people will lobby more and more for alternatives, and you will go under. Solution? Fix your f-ing mistakes for once.

RE: Wait - California smart meters do have problems
So, it is everbody's other equipment that is what: Inadequately screened from a transmission that did not exist when it was created? Seems like your product research would have turned up competing signals and resulted in better screening for your smart meter. Not smart. Also not smart to annoy your customers as they all have lawyers.

RE: Wait - California smart meters do have problems
By the way: remember the old rule of no cell phones in hospitals? Same problem; erratic pulses were retiming iv machines that were delivering very delicately controlled doses of medicine. How well I remember calculating mcgs/kg/min for a tiny neonate.

Well, newer pumps and ekg machines and so on are now screened against cell phone errata but if someone has an old pump in use and it is your neonate. . . leave the phone off.

RE: Wait - California smart meters do have problems
I am not looking forward to when smart meters come to my area. I can only hope by then that I can afford to build my dream home. And I only want the smart meters of MY choice and only IF I can choose yeah or nay on that. I don't want government telling what, when, or how.... I don't really hate smart meters. I hate government mandating this stuff.

Although I don't believe in global warming, I do like the idea of reducing my electric consumption. I just don't want government doing it. Plus, I want to know that if some attack eventually does exist where a virus or some sort infects these things that I can bypass the meter. Oh, like a generator for my home, solar panels, battery backup. As I sit and dream up what I would like in a house electrical grid, it would be some sort of mad scientist's hybrid system.... Just as long as I don't start building death rays when I finally can afford that dream home???

RE: Wait - California smart meters do have problems
Something that was not mentioned, is why are so many people saying that their smart(?) meters adding extra costs? I have a possible reason for that. Since the meters have a problem interfering with the consumer devices, why couldn't those devices be interfereing with the smart meter and causing it to run fast and add to the billing cost?

Also, at my church we have a number of wireless microphones that are in the 900 mhz band. Another article I read says that they might be intereferred with also if they are tuned to the part of the spectrum where the mics are. Just what we would need when the pastor or other speaker is trying to make a point.

We already went through that with the 700mhz band where we had to replace one mic for over $400 because it might interfere with the telephone company's purchase of that frequency.

BUSINESS RULES!!

RE: Wait - California smart meters do have problems
One bit of irony with electric meters. Older mechanical meters experience a bit of wear. That wear can slow a meter down and cause the customer to get a smaller bill. Then comes the day that the customer gets grumpy and complains about their bill, "the meter must be running too fast" the exclaim. The utility dutifully replaces the meter with a shiny new meter (perhaps an electronic meter) that works perfectly - and the customer's bill goes up to its correct level for the first time in years.
Perhaps those people that complained about being overcharged were simply used to seeing bills that were small because of an error.

RE: Wait - California smart meters do have problems
Two more thoughts...
In my area, the utilities are not connected to the government. dedrizen could move to an area like mine - but you'ld still be stuck with whatever meter the local utility dictated. Or you could choose to do without.
For better or worse, we all have to share the airwaves in the same way that we share the air. Technology is finding more uses for the airwaves and thus the airwaves are becoming increasingly crowded. Unfortunately, this means that people are forced to upgrade periodically. Remember not long ago when we all had analog TVs and cell phones (those that had cell phones). They were all forced to go to more efficient digital signals to make room for more newer devices. The alternative is that we would all be stuck with 1990's technology - and only the rich would have cell phones.

RE: Wait - California smart meters do have problems
I've been reading all these complaints for a while in the news. I live in Sacramento Co., but have SMUD electricity "Smart Meter", and a PGE gas "Smart meter". So far I've read nothing about any problems with SMUD's meter! What is the difference between the PGE, and SMUD electric meters???

ZDNET please re-read my comment, it is correct. The meter mfr describes the pulses just as I have observed. I don't know how they do it, but it works.

RE: Wait - California smart meters do have problems
Since there is no REAL benefit to customers (98% of PG&E customers are on tiered billing - Time-of-Use is not offered) because it's not exactly hard to read the old meters - unless you don't really get what the hands on the clock do... it's really sleazy of PG&E to suggest their customers get rid of all their existing electronics so that the meter won't cause a problem. And don't blame older meters for high bills. Our city council member went on vacation for a month and they installed a "smart" meter while she was gone - the bill went from $150 to $600 and nobody was there! My neighbor's garage door has started opening on its own since the meters were installed (she has the closest repeater meter to the access point, with a 50-unit apt. building behind her), people's satellite DVRs have started spontaneously rebooting, and mobile phones now have "clicks" - why should anyone put up with this? Because all the transmission is closest access point, nowhere is really safe from their signals. I don't have a tin-foil hat on yet but I do have a lot of electronics that I care about a lot more than their "smart grid" system for which that they haven't even worked out the security or annoyances yet - I've considered disconnecting service completely - eat out, shower at the health club, and work on my computer at the coffee shop rather than let PG&E tell me how I should run my life! And it's been two years since hackers have started distributing information on the internet about how to hack in to the things. Way to go, PiGEe!

RE: Wait - California smart meters do have problems
I AM doing some research on 'smart meters' because I AM noticing interference.

First after they installed the smart meter, my wireless mouse on my laptop would turn off incessantly during 'peak' hours.

Now during the coldest months of the year, my thermostat keeps coming on & requires constant adjustments (down) to keep the house at 65 degrees.

Replace your baby monitor, anolog to digital tv/channel box, security systems, garage door opener, etc I find that Pigs Goats & Elephants have just jumped on the 'software upgrade bandwagon'. We cannot check our email, surf the web, print, etc without downloading the 'latest' software.

Somebody please, find a work around that is affordable. Gone are the PUBLIC utilities. We ALL need basic heat, shelter, food, water & of course, privacy would be nice...

RE: Wait - California smart meters do have problems
We recently had our meter changed out to the so called smart meters by SMUD. We have no gas service or any services from PG&E. Our electric bill went up $100 last month and this month $110. Two weeks ago(approx.) a SMUD service person came to our property and announced he was changing the meter. I adviced him it was changed already a few months ago. He then said" yes I know butit has been sending in false readings",. At the time I didn't have my second ( highest ever had in past 5 years) bill but they had just taken the reading for it days before. I am postive I am being taken for a ride here but pretty sure I will lose any argument. They are making sure it is not easy to read these units or understand them, I'm sure they don't even understand them yet. How can I not be their testing ground! I'm on SSI ad live in a house that is 100 years old on the last bit part of 'farmland' in the area. I also get their discounted rate for the poor.

EMF Concern
moving to CA and concerned about the smart meters. And since I had brain surgery a year ago I get really bad headaches. Worried the EMF from the Smart meters will cause headaches..

Who are SMUD's contractors? Washington state license plates on SMUD auto?
I will not allow SMUD's contactors to install a "smart meter" nor will I allow them in my backyard. The contractor's auto, with SMUD's name plastered on the side, has Washington state plates. First, Sacramento has many unemployed workers ready, willing and able to go to work. Second, I will not allow out-of state unlicensed scab workers to install anything at my home. According to the Calif. Contactor Board, SMUD, as well as other utility districts (I call these little utility kingdoms) have no control over utility districts and are exempt from state contractor laws. Sorry SMUD, the smart meter is an unsafe, untested, unregulated, inaccurate and perhaps a very dangerous product. SMUD is not going to install their "smart meter" at my home.
