PN2500 Professional NEMA 5-15 Wi-Fi Wireless Level 1 EV Charger Pass-Through Power Usage Monitor (60-240V, 25Amp)

I have a Ford F-150 Lightning with extended battery. I work from home so I do not need to charge daily, so I can afford to charge at Level 1 (120v/15A). I know after the EV is charged, the BMS continues to perform other maintenance tasks such as charging the 12V battery, keeping the EV batteries warm/cold as necessary, and other tasks. I have always been curious when this actually happens and how much additional electricity is used for these functions. In my browsing around Amazon, I ran across the PN2500. I was specifically interested in this model because it is rated at 25A, where others are only rated at 15A. My EV is plugged into a 20A AC outlet. The PN2500 is a bit more expensive as compared to others in this category, but it does have WiFi and APP for monitoring and fine tuning settings. So far, the PN2500 has performed flawlessly. I find the APP (IOS version) to be well designed, provides a lot of live data and so far has performed a lot better than I had expected. Most APPs for devices like this are clunky and hard to use and don't function as expected. This APP, however, is working great!. I don't need to into detail of all of the functions this device has, since there are several other reviewers that have covered that, and did a good job in their reviews doing so. There is one point I would like to make note of. If your mobile devices is using 5ghz WiFi at home, you will need to temporarily change your mobile device to 2.4Ghz. When the APP is first installed, it looks for the PN2500 using Bluetooth. Once it finds it, it starts to configure the network settings. It grabs the network config from your mobile for the initial setup. Since the PN2500 only supports 2.4ghz, and your mobile devices is currently configured for a 5ghz network, it will fail initial network setup. Again, change your mobile to use 2.4 temporarily and the initial network setup will be smooth as silk. At lease mine was. Yes, I had to temporarily change my mobile, but after network config was complete, I switched it back to 5ghz and the PN2500 continues to use 2.4ghz. I''m considering getting a 2nd PN2500. I would recommend that everyone has one of these in their tool box.

Fairly well built device for monitoring my household appliances. Was using it to determine the typical and max draw of certain appliances (KW, volts, amps) as well as power factor of the devices so could determine what all I could use my EV vehicle 120V 1500W outlet as a power source for if the house power ever goes out. Like that it can give not only the current power, voltage, amps, total KWH, apparent power (VA) and power factor, but the max power , max current, max voltage as well that occurred since it was plugged in. This helps to determine what appliances are usable on with my car 120V outlet, what kind of transients could occur during startup or operation, and what all devices I could have simultaneously or combinations thereof being powered by that car outlet.Like that it is 25A max rating which means any 15A appliance is well under its rating. As another poster mentioned devices only rated for 15A probably are more likely to have issues if a continuous current close to that occurs.Also like the app as can easily remote monitor it if it is a place that is difficult to see or inconvenient to get to , plus it has some graph history capability for the power reading.Didn't have a problem setting up the app, and as far as I can tell there is no fee to use the app.

Summary: I have a small Solar/PV system (3000W panels), MPPT and 3500W inverter, so using this energy meter to capture energy usage. Over the past three years, I've evaluated many energy meters, which are the plug-in style without any remote monitoring capability. This Wi-Fi version by PONIIE is one the few offerings that does, and the great feature is the higher amperage rating (more discussion below).Observations: Most house AC lines are 15A or 1875W; and this unit is rated for 25A, which is 3125W. Why this is important is that most low cost energy meters are built to just be able to carry 1875W, which could result in unit heating, which degrades electronic life. In the worse case scenario, the unit malfunctions and/or fails by burning out, and possibly catching fire. As this unit is rated for 25A, the likelihood of that happening is reduce by a fairly wide safety factor (a 15A circuit running over a unit which can carry 25A, is running at 60% of maximum load (15/25).Recommendations: When it comes to electrical load testing, a higher capacity unit will give an additional safety margin.Pros: Good fit & finish; easy to read (and take pictures of) the backlit screen if needed; Wi-Fi connectivity, including circuit control (on/off), and even turning on/off the backlight (also can be done from the face of the unit).Cons: Cost, this is easily 3-4x the cost of an energy meter without the remote monitoring, nor the higher circuit capacity; PONIIE only has five items listed (this is a concern on whether the app will be kept up to date).Conclusion: At $60, rating this 3-stars (cost, new manufacturer, uncertain software longevity).

I purchased this to log power usage and based on the app's picture and device's WiFi ability, I expected to do some data logging with it; however, while it will connect to Home Assistant, using the Tuya integration, the power meter only sends volage and then separately, current, each about every 4 seconds. Watts are not sent, neither is KWh. Of course you can calculate watts from the received data, but the measurements (I and E) are separated by roughly 3 to 200 milliseconds (I'm assuming they come in separate packets). The power meter would do excellent in providing immediate gross power readings or for a measured time span (for example, 24 hours). In summary, it appears well built, good display, legible multi-function buttons, app is usable, integrates somewhat with HA. Downside is the limited data logged in the app and transmitted via WiFi.

This is my second purchase of a Poniie Professional Monitoring equipment Tool and I found that it works really well!Poniie Professional is certainly Not a "one-trick pony!"I will try to keep my eye out for future innovations, as these are far more affordable, than leading brands.This Electric Power Usage Meter has many more features than similar products and was much more affordable!This Poniie PN2500 Professional Power Usage Meter is so beneficial with pinpoint accuracy that I was able to do all of my own electric modifications, as needed. My Poniie PN2500 is sure to be the Most Valuable Addition to my toolbox, out of all tools, from my many recent purchases.I now know that my home voltage of power delivered from the electric grid is Too High, as I saw spikes of 127-130v, instead of 110-115Vac. Now I know why my LED bulbs have been prematurely dying. Even at 24 hrs a day usage, vs 3hr recommended, a standard LED bulb should last at least 2-3 years, not 6 months or less. Most LED bulbs cannot handle excessive waste heat, as incandescent ones did and it's likely causing them to short.I did not have use for the wifi feature, but it's nice to know that it is available if needed.Also, The wattage used log came in handy, for usage monitoring to locate and remedy control over Electric energy hogs..

So far so good, all that is left is the test of time. I will update if it fails.Great unit. Easy to use, has all the key metrics to monitor, app is clean/good (see photo).Physical size of the PN2500 is practically identical to the Kill-a-Watt EZ P3. In height, width, and thickness (See photo). But unlike the P3, the PN2500 has Wi-Fi, which is an absolute game changer. No more bending over in awkward places where you have this thing set up to see the results, it can all be done from the app. Additionally, the app lets you change settings, so you can update your energy rate, toggle the LED on/off, etc from the app.The app was around 65MB, I installed it on a Galaxy S9+ with no issues. The app has a Guest login! So you do not even need to set up and account to get all of the basic monitoring features. You can get it up and running without directly providing any personal information (name, email, etc.) to the company.Additionally, this unit supposedly has a Max Power rating of up to 3000W @ 120V, which absolutely smokes the P3's rating of 1800W. I have burnt out several P3's when using around 1200W, which is why I no longer trust those units. Hopefully this PN2500's 3000W rating will be accurate. That would unlock the ability to monitor things like small space heaters (the notorious killers of the Kill-a-Watt P3's).I have not had the unit long enough to comment on its durability. But if the unit fails I will update this review. No update means the unit is still going strong.

I recently acquired two PN2500 devices to monitor the electricity consumption of my two AC units. My primary objective was to gain a precise understanding of the associated energy costs. Upon receiving the devices, I read through the instruction manual and observed that the default cost was set at $0.125/kWh. However, residing in California, I knew that my actual electricity cost per kWh exceeded this value.In order to ensure accurate measurements, I cross-referenced the cost with my latest Electricity Bill, which indicated that during "On Peak" hours, the cost per kWh was $0.73250. The discrepancy was substantial, prompting me to rectify the value immediately through the designated mobile application.One aspect I noticed while using the app was that the energy cost input field was confined to a scroll bar, rather than allowing manual entry of the precise cost. Regrettably, the maximum amount allowed by the app was limited to $0.500/kWh, which fell short of my actual cost.Despite this limitation, the PN2500 devices themselves functioned admirably, efficiently capturing energy consumption data and presenting it in a clear and comprehensible manner. The real-time insights proved invaluable in making informed decisions to optimize my AC units' usage during peak hours.I earnestly hope that the app developers will consider adding a feature to directly input custom energy costs, as this enhancement would further elevate the utility of the PN2500 devices. Notwithstanding this aspect, I still find these devices to be a valuable addition to my energy management toolkit.Overall, the PN2500 presents a user-friendly and informative solution to monitor energy costs for AC units, offering valuable insights for those seeking to manage their electricity consumption more efficiently.

Very accurate, easy to use, good quality.
