Sense Energy Monitor - Track Electricity Usage in Real Time and Save Money - Meets Rigorous ETL/Intertek Safety Standards

I'm Thailand customer who want to try this cool gadget.Of course, the warranty will automatically voided.And i'm fully awared my risk and acknowledged.I hope my review could provided valuable information for other international customer.And you may use it at your own risk.My electrical system. (In Thailand, which is common in EU-standard.)Is 1 Phase (Non-split like US), 220 Volt, 50 HertzWhich means... i have 2 wire goes to my house.One is LINE, another one is NEUTRAL.And voltage across Line-Neutral is 220 Volt.I'm am Mechanical Engineer and have some basic knowledge about electrical system.So, i'm doing this on my own (With my Dad's help) without certified electrician.We use extremely caution, and use probe to double check which wire is Live (Always have electricity) and which line is Neutral.Installation step :(Find the picture) I detach the main-panel and on the left side.You will see main circuit-breaker with two big black-wire (That coming from power-line) connected to it.Black wire on the LEFT pass thought breaker and connected to upper uninsulated Bus-bar. (This is Neutral zero Volt)Black wire on the RIGHT pass through breaker and distribute electricity through all of Circuit-breaker on the right. (This is Line 220 Volt)For electrical wiring, i have two breaker empty (the 6th and the 7th)So, the Black-wire (Power supply & voltage sensing to SENSE) goes to 6th breaker.And White-wire obviously goes to upper busbar (Neutral)For the Current sensing (The clamp), just attached only one to the Line.Setup :When i switch on the power.The app show that something wrong with the installation :)I just continue and go to the main screen.And yes, its showing Power consumption for only one phase.Testing :I do initial testing, like turn on the light.Use the Induction hobs, oven.The app show the power consumption very accurate.Problem :Yes, i use this in Thailand.So, after 3 hour of data-sampling. The main menu indicate warning say about"Sense detected an installation problem and unable to fix automatically. Support team will take a look."Because i use only one phase with abnormal 220 Volt.And SENSE probably cannot analyse my current and voltage data to map electronic devices in my house.I'll try to contact SENSE team... if they could make my account as an exception.And analyst my data...Another problem is, when SENSE was running for a while.The real time data of Power (Watt) indicate the app seem to be shift. and its getting larger by the time passed.For example, on the 10:45 its showing live feed of data on 10:40.I thought this might be internet connection or bug. So, i reset my router and SENSE.Its still happening and three hour passed. The gap was larger.Like.. on 13:50, SENSE live-feed time showing data from 13.35 !Conclusion :Regardless to problems (exclude i cause by using it in Thailand).I'm satisfy with the futuristic concept of tracking power consumption in household.The setup was quite simple, If you have electrical knowledge.If you don't, just call professional guy to take care that for ya.I can't try this AI-feature yet. But still love it !Update : 2/2/2020Day 0After SENSE detected installation problem and cannot analyse electrical signal to map my house appliance.I've sent an email to support team to unlock or by-pass.And at the end of day, App show that installation diagnosis is OK and start listening now.Day 1My Pressure booster water pump was detected. (Brand : Grundfos)App saying that most user voted this might be 97% match to the "Pump"I do some verification, on the pump on.. see if SENSE detect this pump.And yep, this is definitely the pump.Day 2Sense notify that two new device detected.Heater & Motor...Identify the "heater" was a little bit difficult.Because i have... Water heater, Rice cooker, Induction stove ?But after i click at the usage data. I can see that this Heater was active around 6 p.m.At that time, i was't shower or use the stove !So, 100% this is rice-cooker. (Electrolux-brand)App suggest Coffee maker 50% & Rice cooker with 40% confidence, Good guess !For motor, i just click and see the activity.This one was active on 11:00 p.m. until 8:00 in the morning.Also, it keep cycling ON-OFF for 50-70 times during nightApp suggest this one was A/C with 97% confidence !

I had the Sense Home Energy Monitor installed when my service panel was upgraded by an electrician. It was an ideal time since the power was off to the service panel. The system physically only took a few minutes to install. I installed the App on my phone and then when power was restored I detected the monitor via Bluetooth and then added it to my WiFi network. Realistically, will I save enough on electricity as a byproduct of the insight from this $300 monitor to justify the cost in the next 2 or 3 years? No, but the insight is enlightening, and the given enough time and appropriate actions you could eventually justify the cost. After about 3 weeks of use my monitor discovered the following: fridge, microwave, dryer, TV, receiver, boiler, space heater, garage door and the refrigerator light. I would call it a guided discovery process. Some items were identified with high confidence, while others required user intervention. The monitor displays a potentially discovered device and list of choices of what the device most likely is. As a user you can guide the monitor into identifying what the device is. Additionally, once a device is discovered you can supply additional details such as a descriptive name, make and model number to help Sense build out their repository. The monitor shows power consumption in near real-time so devices and circuits can be toggled on/off to help positively identify the device consuming power. To me this monitor is like a big data/analytics mashup with community input help to build a progressively more robust repository of devices and their consumption patterns. If nothing else this monitor provides insights and tips that might modify your behavior once you have a better grasp on what "normal" power consumption is for your home. To truly get the value from this monitor you need to give it a few months for the discovery process and be willing to provide feedback. If you are fine with that expectation, this is a fascinating exercise in analytics and human interaction. The app is easy to use and intuitive. The app displays daily, weekly, monthly and yearly historical power consumption for each device. You can supply the rate you pay so costing information can be provided. It would be nice if the app offered projections of what it might cost to run a device weekly, monthly, and yearly.
