The last step of the physical install is to connect sensors to the individual breakers you want to monitor. Ideally, I’d like to program more complex Time-Of-Use rules to enable certain loads based on time and load status of other loads. This is done, in my case, on a Ubuntu machine that runs an Intel processor and has the required tool chains available. For a distributed system I would point you to the PZEM-004T as the measuring device and ESP8266 or ESP32 programmed in the Arduino environment as the comms link to datalogging via MQTT.

Above is the monitor and the two main sensors that clip around the power leads into your electrical panel. My home has a very small electrical panel, so the electrician faced a challenge getting all the sensors and wires to fit, as you’ll in the next picture.The WCS is a voucher-based scheme designed to provide eligible applicants with support towards the upfront costs of the purchase and installation of EV chargepoints.

The unfortunately bit here is that if you are in the market for an energy monitor today, it means that the top pick has a good chance of being yesterday’s tech tomorrow. The rules can be arbitrarily complex, conditioned on time, relative delays, power level of a different device, previous state changes, etc. so if something drew 0 watts for 2 seconds and non-zero for 3 more it would not show it was at 0 watts for part of that time.Knowing what each device/circuit is doing, and when, can be useful, but it does not, in itself, change usage and habits. It will do everything that you list, it uses a voltage transformer for a voltage reference, so measures power correctly. Costs can vary depending on where the energy is pulled from — burning fossil fuels or green, for instance.

To compute real power (Watts) is the average of the products of voltage and current of each sample pair. If I need to recompile, I just start up ESPHome, go to the dashboard, load te configuration file, tweak it and send it back to the Emporia - no muss, no fuss, I just have to remember to do it via Chrome instead of my normal browser (Thunderbird).Is that in addition to adding devices to the energy dashboard, or instead of the energy dashboard integration. The Emporia Gen 2 Vue Energy Monitor features, and associated app, nearly make up for installation woes Emporia Gen 2 Vue Energy Monitor provides clear data on your energy usage.

Anyone who has this hardware interested in working to get it supported with something like ESPHome or Tasmota? The versions with 2 main clamps i think are the USA deign and they have split-phase supply there, so it just happens to have the 2 clamps out of box.

APPLIANCE MONITORING WITHOUT GUESSWORK: Comes with eight (8) 50A sensors to accurately monitor your air conditioner, furnace, water heater, washer, dryer, range, etc. billt is right about the benefits of the more compact toroidal CTs if you're prepared to pop a few wires off the busbar (you can use circuit Neutrals) but without lots of tinkering you might not be able to make them work as plug-and-play with the Emporia. It supports either single-phase up to 240VAC line-neutral; single, split-phase 120/240VAC; and three-phase up to 415Y/240VAC (no Delta). To begin with, Emporia Gen 2 Vue Energy Monitor provides clear and concise details about day-to-day energy consumption. In France it is the meter “LINKY” of ENEDIS which makes it possible to see in detail the consumption of each apparatus.
