PZEM-004T Current Voltage Power Energy Multimeter Module AC 80-260V 100A with Current Transformer

Product Information

I used the logger settings: VERY_VERBOSE. But I can’t understand whether pzem004t works or not. [16:17:54][I][app:100]: ESPHome version 1.14.3 compiled on Nov 26 2019, 16:12:47 Cannot running on Windows 10 64bit. Even when i set its compatibility with any Windows options. Also even when i… HW Serial conflicts with Debug output. It can be used however without having any Serial Console output

Note: Reply current data is D2D3 = 11 20, 11 represent the integer-bit of the current, 20 represent the decimal of the current, the current decimal is two digits, converts 11 to decimal is 17; converts 20 to decimal is 32, so the current current value is 17.32 A. The Peacefair PZEM-004T features a built-in button on the panel, used to make the electricity clear function. Precautions: ich hab ein MeanWell Netzgerät und anfangs auch alles über das Netzgerät versorgt. Allerdings hat das ja komischerweise nicht funktioniert. Deshalb bin ich auf die Idee mit dem USB Anschluss gekommen. Sending commands and replying data automatically are as shown above, the data are expressed in hexadecimal; the last byte of the sending and replying data are 1E and A4, belong to cumulative sum. At sending commands: B4 + C0 + A8 + 01 + 01 + 00 = 21E (use the hexadecimal addition), the cumulative sum data is 21E, take the last two bytes 1E to be used the cumulative sum data in sending commands; data in reply: A4 + 00 + 00 + 00 + 00 + 00 = A4 (use the hexadecimal addition),the cumulative sum data is A4,which is the cumulative sum data in reply. Habe mir heute die restlichen Sachen besorgt. Nun blinkt alle 3sec nur die linke Diode von den PZEM Geräten. Alle drei synchron.

Please take a look at my web-based app for PZEM devices. It has much broader abilities than this one.) I was a bit surprised at the 10V drop when I turned on the kettle! Also, you might notice that VxA is not exactly W. I don't know if this is because I do the readings a second apart, or because of power factor, or because of something else. I'll look into it.) I have negative peaks in Watt’s … not sure why the sensor would give such big negative values (around -2500W a dozen of times a day (not night when all is quite). I think it happens when there is a higher load. begin: Initializes the Preferences library. It takes the namespace and a flag that indicates whether to erase the existing preferences or not. Setting the second argument to false ensures that existing preferences are not erased when the device restarts. 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. Can you measure the secondary current of the supplied c.t?

AC communication module PZEM-004T V3.0 User Manual

VV][scheduler:185]: Running interval 'update' with interval=60000 last_execution=32987795 (now=33047795) I too have a PZCT-02, which came with a PZEM-022, so it’s looking very likely that the input is 100 mA. Note: the PZEM-016 TTL output is at 5V signal levels. There are varying schools of thought on whether the ESP82xx has 5V tolerant GPIO. You may want to use a level shifter for the serial communications signals to bring them to the recommended 3.3V. so it seems that the third nuber is active power so cos(fi) is inside it.. and that the last number is the sum of energy used.. quite useless, isn't it? Versuche es mal so (PZEM Rx und Tx habe ich getauscht) und wenn es auch nicht geht drehe hier mal die Dioden.Mit der Software kann übrigens das Gerät auf Funktion überprüft und auch Kalibriert werden, wenn nötig! VORWEG, WEISE ICH DARAUF HIN, DASS ICH KEINERLEI HAFTUNG ÜBERNEHME UND ICH SAGEN WILL, DASS DER ANSCHLUSS DER PZEM-004T MODULE VON EINEM AUSGEBILDETEN ELEKTRIKER ÜBERNOMMEN WERDEN SOLLTE UND NICHT VON EINEM LEIHE!

Although there are some differences between PZEM-004T V2.0 and PZEM-004T V3.0, functionally or featureally, both have similarities. Following are the features or specifications of the PZEM-004T module : The serial communication function (comes with TTL serial interface, through various terminals to communicate with the adapter plate, read, and set the parameters). Make sure the PZEM device is connected to the 230V AC power! The 5V pin only powers the optocouplers, not the actual chip. The Version 3.0 PZEM is an upgraded version of the older PZEM-004T for which you can find the library Here Main features hab inzwischen alle mögliche Variationen ausprobiert. Sogar einen anderen Wemo eingesetzt, falls der andere einen Schuss hat.

The PZEM-004T sensor is connected to the microcontroller (e.g., Arduino, ESP8266, or ESP32) using jumper wires. The current coil is clamped around the wire carrying the AC current to be measured.

It can be used a SMD resistor 102 or 1001 (1K) soldered near/parallel with R8 or a normal resistor (THT) similar to that used on the image of v.1.0 The resistor is placed in different place on v.3.0 because the optocouplers RX and TX are reversed compared to v.1.0

Die 5V Spannungsversorgung der PZEM Module muss über den Wemo kommen. Nur dann erhalte ich eine Kommunikation. Ich vermute mal, dass liegt am Potenzial für Tx und Rx. If I do go that route what impact will this have on measuring a 3 phase system? In other word using 3x PZEM-004 devices with the smaller CT’s to measure the 500 A feed.
