More than ever, there is a need to be able to stream-process, filter, mask, transform, aggregate, analyze, and route that data to various data tier destinations optimized for specific usage.

Power Monitoring System Using Pzem-004t and Bharath Pi

It is capable of measuring four interrelated electrical variables as voltage, current, power, and energy. PZEM-004T module is very easy to use in programming using various types of microcontroller boards such as Arduino, ESP8266, STM32, WeMos, NodeMCU, Raspberry Pi etc. Run the wire through the circular sensor and you`re ready to start measuring the voltage, current, and power. Because it uses a split core, of course it has advantages in its ease of use because it can be directly installed on a power network cable that is already installed without having to remove the power cable. This module is an upgraded version of the PZEM-004T with frequency and power factor measurement features, available at the usual places.Die direkte USB Verbindung mit dem Laptop hat ja funktioniert aber mit dem Wemo, klappt es komischer weiße nicht.

PZEM-004T - Hardware Using a Larger CT with a PZEM-004T - Hardware

I think it is highly likely that the 1 A secondary current (at the rated primary current) will be far too great for the device. Edit: An den Rechner direkt kann ich sie nicht mehr hängen, weil ich das Usb Kabel zerschnitten hab, um es an den Wemo anzuschließen.t.; and then use 10 turns in the secondary winding of that to give you 50 At to indicate 50 A on the instrument using its original 100 A c.

PPPS: i've removed from the code the debug and logging code, so maybe i left some typo or formal mistake. Pzem-004T an die gleiche Phase (L1- L3) wie der zu Messenden Stromkreis anschließen, da es sonst zu Messfehlern kommt! mΩ, so that the 1 A current shares 900 mA through the second burden, and 100 mA through the instrument, and pro rata at lower currents. Alles nach folgendem Schaltplan verschalten (Pzem-004t Module müssen mit 5V Spannung versorgt werden, nicht sichtbar auf dem Schaltplan).I have copied my code below, and for what you are looking for I think could be done with ESPHome Automations, use spare GPIO as switch and use the values as sensors. If prefer, you could change the value of the optocoupler’s resistors by following this or this guide. The PZEM-004T together with a HW-655 Relay provide a good clamp-on energy monitor for a 240V clothes dryer. Everything depends on the accuracy of that, combined with the accuracy of my estimate for the burden presented by the instrument.
