User questions & answers

Question:	Can this be set up to use and view on a desktop computer or does a person have to have a cellphone
Answer:	The OUT signal is a simple on/off detector with no adjustments. However, the analog detector signal can be tapped at pin 12 on the IC. The output is not doppler. The RCWL-0516 appears to be a free-running 3 GHZ oscillator tank that moves around in frequency depending on multipath resonances in the near environment. I did try doppler-like detection at very close proximity, and was able to see heartbeat frequency on pin 12 with a digital scope. If you tune the chip placement inside a Cantenna, it might be highly directional. Happy Hacking!
Question:	Does this work with a 240 line
Answer:	Customers who bought this module for their own DIY projects did not say that permission/certification is required to use this module. And no one is saying this product is illegal. Thanks
Question:	Any monthly app fees
Answer:	You need a transistor or Mosfet to either control the motor directly or to activate a relay that can turn the motor on or off. I have notes on this unit on my web page - they may help See: http://www.trainelectronics.com/MicrowaveRADARSensor/index.htm dave
Question:	Is there a subscription needed
Answer:	Sorry for the misunderstanding It means this module can detect human or rat or cat

Turning Power Into Knowledge

Emporia has developed the next generation of the Vue Energy Monitor. Committed to bringing the best value as affordable possible, the Vue provides everything you need to monitor your entire home's energy usage in real time. See how much electricity your home is using anywhere, anytime.

Monitor Individual Circuits without the Guesswork

Add individual 50A sensors to your Vue to monitor up to 16 individual circuits — providing accurate energy use for the appliances and equipment that is important to you. No guesswork. No trying to discern energy signals from background noise. Just simple, easy, and accurate insight into your home. 50A sensors are sold separately and also sold in bundles with the Vue.

Measure Solar Net Metering without Extra Hardware

Solar net metering is built right into the Emporia Vue. The simple Emporia iOS and Android app will show when and how much electricity you are consuming and when and how much excess energy you are producing back to the grid — giving you keen insight into the impact of your solar panels as they relate to your energy use.

Installs in the Electrical Circuit Panel of your Home

The Gen 2 Vue installs in your home's electrical panel using CT sensor clamps that go around your mains and the other circuits you wish to monitor. DIY instructions included, but a professional electrician is recommended. The Vue system is designed for field installation in a switch enclosure as per 312.8(B) of the 2017 NEC regarding Power Monitoring Equipment.

Do You have Metal Bus Bar Mains in Your Panel?

Our Flexible Current Sensor solution is now available on the EmporiaEnergy website. These current sensors are meant to replace the 200A main sensors that ship with Gen 2 Vues. They employ a bendable Rogowski coil with a 1.4” (36mm) opening that can fit around most bus bars or into tight spaces where a standard current sensors clamp cannot fit. Installing the Flexible Current Sensors is still dangerous, and Emporia highly recommends that installation be performed by a licensed electrician or other qualified professional.

Add Emporia Smart Plugs to Your Vue

Emporia Smart Plugs (sold separately) can be added to your Vue system to help you to not only monitor the energy of lighting and small appliances, but to also set timers, schedules, and turn them on and off from anywhere, any time with the Emporia app.

User questions & answers

Question:	With the solar system, will Sense pick up and track the electricity that goes back to the public grid
Answer:	Yes, it can detect through sheetrock, glass. As far as wood, it depends on the thickness.
Question:	is there an API
Answer:	I have not used it yet but the board is labeled but only slightly. If you look at the edge of the card where the harness in the picture on this product description, there is a + on the bottom pin and an O (IO) on the top pin. The White plastic harness covers the lettering up a bit. The center pin would be the gnd. This is a guess.
Question:	Does it have an ethernet port, or is it just wifi
Answer:	These sensors are actually omnidirectional. If anything, they are often a little too sensitive and respond to noise in the power supply.
Question:	Since this is a cloud based service, what happens if, heaven forbid, the company goes belly up and closes? Since processing isn't in a local app
Answer:	Below are some links I came across that helped me het the sensor working. https://github.com/jdesbonnet/RCWL-0516/issues/2 https://tech.scargill.net/microwave-for-the-weekend/ https://github.com/espressif/arduino-esp32/issues/855

User questions & answers

Question:	How do I do solar monitoring
Answer:	Not by itself! You may be able to in conjunction with other sensors or with multiples but that would take some coding and algorithms to make happen.
Question:	Does the Eyedro module run off mains power? If so, what power output is the supplied power supply
Answer:	These are very very sensitive devices, I can sense movements from my neighbor so I think that a plastic box won't help a lot. There is a possibility to add a 1M Ohm resistor to reduce the range but I didn't test it. Take a look at this blog http://www.rogerclark.net/investigating-a-rcwl-9196-rcwl-0516-radar-motion-detector-modules/ from Roger Clark, plenty of good information there. Good luck!
Question:	I have huge privacy concerns! i would love to purchase your product if it didn't require me to upload data. can i run local software without upload
Answer:	I would call it "active high" - the output goes high when a detection is made. . .
Question:	I need a system to track electric costs by subpanel...can you recommend one
Answer:	Needs to be in some sort of enclosure. Doesn't sense through glass, but does through plastic or wood.

User questions & answers

Question:	Can I use it on a gas dryer that takes 30 Amps for a split second to start? I know it runs below 8 amps once started
Answer:	Its a crap shoot as to whether this meter can handle the surge current of start up. Maybe itll work once, twice, a few times. But eventually it WILL fail. Id recommend one of those add in power monitor displays with a split core transformer that is clamped around the input hot line to sense current. For example, a CrocSee CRS-022B. Much, much safer. And can sense up to 100A!
Question:	can be used connecting 220 Volts at 60 Hz
Answer:	Yes, this item is designed for 110-220v, 50-60hz, AC power.
Question:	Can you plug space heaters into it safely
Answer:	It depends, the max. wattage rating of the PN2000 is 1760w @110v or 2000w @125v (16 amps). As long as your space heater rating is lower than this, it should work. Most space heaters have a max. output of 1500W, so you should be good to go. Note: Due to the large start-up amps of space heater, though device has abilities to deal with it, we still recommend not to use the device near the max rated specs (in most cases, the true RMS Current will be around 15A) for a long time to avoid any unexpected damage or accident. And please kindly know that the inner and outer device material is fireproofing. If device is over used or exposure to excessive heat, it may cause a melt incident but it won't start a fire. Still, you need use this device carefully to avoid any fire hazard.
Question:	Does it tell you how much electricity has been used in 24 hours and the cost of usage
Answer:	Yes, it will give a total usage over any time period (loose power circuits will be fine, consumption kWh will be kept in memory). So you just need to let it run 24 hours and check the Electricity Consumption (EC). Regarding the cost of usage, you have to do the math. Here gives you an example: Let's say your billed KWH is 0.07 and the distribution charge is 0.04. Then the KWH charge $0.07 + distribution charge $0.04 = $0.11 per Kilowatt Hour(kWh) usage. So if your device is using total 2.4 kW-hrs(EC) per 24 hours (which is equal to 100 watts in one hour), then you are paying $0.11 per kWh * 2.4 kilowatts per day = $0.264 for each day of use. Hope this explains it better.

User questions & answers

Question:	Will this unit display amperage
Answer:	I would recommend Eyedro. You will need an Eyedro for each panel. You can then associate them all to one account for real time viewing and get a weekly report with usage and costs. I am monitoring my home, cottage, a rental property and a washer/dryer pair (for kicks).
Question:	Works on AC 120 Volts
Answer:	It tracks solar generation. It also tracks all power usage in real time. So it is possible to determine how much of the power generated is used in loco at any given time. Thus it is also possible to know how much excess there is feeding back into the grid. -- But Sense does not present this information as a separate item.

User questions & answers

Question:	Does it work with tri-phase 220 current
Answer:	There are no provisions for any external data interface - it's just a display module. It does store its last KWh reading if power is removed. For what it is worth, I separately bought a couple of external CTs and found them to be consistently accurate, including with the donut CT.
Question:	can i use 2 expansion boxes with one controller? or do i have to have 2 controllers to go past
Answer:	Update: The new Eyedro WIFI (EYEFI-2) model does support solar monitoring (directional sensors, true power, amperage, voltage, power factor). https://www.amazon.com/Eyedro-Electricity-Monitor-Supports-Metering/dp/B07KBBD8C5/ Please contact us if you require additional info. Thanks, Trevor (Eyedro)
Question:	Can i install two expanded units in the same house (2 breaker panels) using the same app? - - so, 2 main 220v feeds (plus the 8 in each breaker box
Answer:	Yes, my Eyedro module is powered by a 120VAC to 5VDC adapter. The manufacturer support info (including product manual) is at eyedro.com/support
Question:	The description says it's accurate down to 2a. what is the variance below 2a? will it record any energy usage below that value
Answer:	Privacy? You're concerned about a company knowing how much electricity you use? Ok. I would love to have the option to connect to the device with an API also, but that's just because I'm concerned their cloud service would go away if the company ever goes out of business.

User questions & answers

Question:	How can i ask for a zw095 to support eu frequencies and 230v? does this product support it or how can i order one
Answer:	Yes, this records the total power used by the device whether it is on or off or any mix. You just need to go to the screen kwh used. record the beginning # and at the end of time period (say 24 hours) record the end #. that is how many kwh it used. I used several of these for months to record the A/C use in our shared apt and paid the landlord for the a/c used so they don't complain about my electricity used. great device. now however, my apt has a 20a a/c wall unit. while you could get converter to regular 3 prong, not sure if this unit will go to 20 amps.Others who said no are simply ignorant of this devices menu. It ALSo shows, when on watts menu, the watts used when a device is running, or is off. so you can see how much your a/c or toaster oven or giant screen tv uses when on, or off.It also keeps the power kilowatt hours used even if unplugged or power goes out in its internal memory. so you can simply record the kilowatt hours at the begin of a month, then at the end of the month, subtract and multiply by your cost of electricity for the total $ / month the device uses.The dork who was our landlord at the time thought his electric water heater for tea was less expensive to use than nuking a cup of water for a minute to heat it up in the microwave. popped this device on it and they were almost identical in total power used to heat a cup of water.The same idiot who was complaining about this left his rear projection tv on when he wasn't around, and they use alot more electricity than today's flat panel screens.If you want to record the power usage of some device over time, you'll want to plug this device into a short extension cord. if you plug it directly into the wall then you have to lie down on the floor to read the kilowatt readings. I just put the readings into a spreadsheet when I was recording monthly electricity usage.
Question:	If installed inside the breaker panel, how is it possible for the device's Zwave RF signals to pass though the panel's solid metal construction
Answer:	This EZ model does NOT display how many Watts you device is pulling... It displays how may kwh have been used thus far, to the 1/10th decimal place. So, when you first plug something in is shows ZERO, since not enough time has passed to show kwh used yet. This is a HUGE feature left off this device. For me, I want to plug something in to a meter like this and be able to instantly see how many Watts the device uses, and this EZ meter version does not do that.
Question:	Does this need a memory card to store data? Can you monitor data over a period of months or just real time
Answer:	Thanks for your question. It is about 19cm long. Hope it can help you.
Question:	What is the difference between Gen 2 and Gen
Answer:	Very minimal. Uses a very small gauge signal wire, hardwired into line voltage. Advise contacting the vendor for a complete spec sheet.

User questions & answers

Question:	does it mearsure watts
Answer:	Time/Watts/Cost Time/Volts/Cost Time/Current/Power Plus two more modes
Question:	How do I install batteries and what size battery
Answer:	No visible battery door, hatch. Since it plugs into power when in use, if there is a battery, it's charging when being used.
Question:	Is this rated for 15a/1800w continuous? in other words, what happens if you connect it to an ev charger, which will draw 15a all the time
Answer:	Yes, rated15A continuous. Only draws about 1 watt (0.008 amps) by itself. Basically, it will draw what the EV charger draws. If you get one, you will see that the EV charger draws max load early, then power draw dwindles as the car gets closer to full charge. It will not draw 15A continuously. You will also be able to measure the watt-hour capacity of your electric vehicle's battery storage. Plus it makes you cool without smoking cigarettes. Very cool.
Question:	Having an issue with 2 outlets in my house and I need to track the power at them. When they lose power and when it came back.Do these keep history
Answer:	I dont think these are what your looking for. They do a great job tracking power used, but there isn't a function for testing outlets.
