The Frient collects readings from your existing electricity meter and, via a compatible hub, sends the data to a connected device. We like the relative simplicity of the Frient Electricity Meter Interface. Provided you already have a smart home meter, you can have it out of the box and sending readings within minutes. Compatibility Once it’s installed you must keep your eye on the sensor logs (see screenshot above). You are looking to see how many amps it’s reporting. The idea is we must calibrate the sensor by telling it how much current was really going through the cable when it was reporting a specific value. So in this example the sensor is reporting 0.035 A but my inverter is reporting a real value of 10.87 A. If you have invested in solar panels, you should be able to report on the return on that investment.
At the top end of the spectrum is device monitoring by reading energy signatures flowing throw the main pipe.Exceeding these figures will cause inaccuracy in readings from the sensor in question. Technical Specifications (large sensor) You can see live readings at 12-second intervals and a historical representation of your usage. Data is presented in graphs that are easy to read, with plenty of export options and analysis. We are not currently aware of a device that implements this which supports a local API and is compatible with Home Assistant. Reading the meter via a pulse counter Most importantly, however, it's easy to see what you have spent over a day, week, or month. If you subsequently make changes to your consumption, the dashboard can tell you if you have improved your usage habits.
If you have a smart gas meter you can use your energy monitor to assess how much things like your gas central heating or gas oven cost to run. However, it’s a bit more complicated than with an electricity energy monitor because the display isn’t updated in real time. This sensor will increment by 1Wh from the time the sensor was introduced. The current epoch timestamp (in seconds) is converted to hours. An offset of 459543 is then deducted before dividing by 1000 so that the increment is 1Wh rather than 1kWh. Unlike other energy monitor apps, the Sense app crunches your energy usage data to reveal trends and insights. As a result, this helps you to reduce usage and save money! The best smart home energy monitor provides real-time data and insights, allowing you to make informed decisions to minimize your energy bills and reduce your environmental footprint.The Shelly EM is an energy monitoring device which can use a current clamp to monitor the amount of energy being drawn from the power feed that the Shelly is monitoring. I wanted to use the Shelly EM to monitor the total power consumption of the house, which will involve installing the Shelly EM on the main tails that come in from the meter cupboard into the consumer unit. Once installed into your home energy panel, it starts monitoring the energy consumption within just a couple of seconds. The smartphone app connects with the system instantly. Wiser is compatible with Phillips Hue, Wemo Insight, and Kasa Smart Plugs as well.
A challenge when expanding your smart home is to centralize control into a single interface. Also, it's great to connect your real-time energy data with other smart enabled devices. This challenge was the reason behind IFTTT. This is a web-based integration layer to allow multiple smart devices to interact with each other.
Welcome
You may also be able to access your energy monitor display on your computer or smart phone, including viewing analysis charts. Over-active AC units; poorly timed hot water circulators, heaters, and thermostats; broken extractor fans; old lighting fixtures are just some of the devices if fixed, can result in serious savings in money per month. Avoid Disaster Firstly you need a microcontroller, and in this case you must get the D1 Mini, and you must make sure it either comes with soldered headers or that you can solder the headers on to it yourself. When you solder the headers on, you must make sure that the pins are pointing down and the main chip and antenna are on the top. And why is this so important? That’s because of the second component…
