Device for Energy monitoring

the topic is not new and users actually reported the mileage they had with that “technique” (current clamp/coil only) already

Home built energy monitor using ESP8266 doesn't see small loads

What you actually building is a current meter and than make a (too) simple assumption to make a guess of your energy. That could theoretically even work when you only have resistive loads (like the good old incandescent light bulbs ) but it will be close to impossible to get anything accurate calculated for a normal house hold use were lot’s of power supplies and various power factors come together The problem is not only that it’s very unlikely that your volt…

Energy Tracking - CT Clamp Current Sensor

Can it be enough to know the rms voltage and the current at the same time without taking the power factor into account to be able to distinguish between active (kW) and reactive (kVAR) power? Doesn’t the rms voltage and current only allow you to get the apparent (kVa) power? That would be a indication that you only measure the apparent power and not the active power that you are pay for The change is rather high that when you use a higher power device th…

Will Low Cost ESP8266 4 Channel Power Monitor Work With ESPHome?

The headline “Will Low Cost ESP8266 4 Channel Power Monitor Work With ESPHome?” is actually misleading. The website states that the product shown in the picture from @Jonah1970 is actually a “ESP8266 - 4 Channel Mains Current Sensor” Accurate power measuring will be impossible with that type of device The blue uses the internal ADC from the esp while the green board uses a (better) ads1115 - still both only measure current and not power Does it matter at all? Wha…
