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

Product Information

I had attempted by connecting the RX-TX cables in both ways (cross: RX to TX and vice versa, or ther direct, RX-RX and TX-TX). All automations you define in ESPHome are executed on the ESP itself and will continue to work even if the WiFi network is down or the MQTT server is not reachable. After setting-up the Cayenne Dashboard, we must test the PZEM-004T V3 meter before interfacing with the dashboard. The Riemann calculated numbers go down sometimes, but I guess this is due to the negative W’s above.

I am trying to connect a PZEM004T (without display) to a USB port on my PC via a USB-TTL adapter board. 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. I have three PZEM v4, powered at 3v3 from a single Wemos D1 mini, using the diode multiplexing suggestion in this thread. You may want to use a level shifter for the serial communications signals to bring them to the recommended 3.

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. 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).

please note I’m new to HA but since my first successful test was with PZEM I try to share my experience. Note: 14 in the sending command is the alarm value (14 is a hexadecimal data representation, which converted to decimal is 20). Ansonsten schauen ob alle Spannungen ankommen, dass es keine Kontakt Probleme gibt, Durchgang messen.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. As most parts are connected to high voltage AC it is recommended to fit the hardware in a solid enclosure. Note: Reply power data is D1D2 = 08 98, converts 08 98 to decimal is 2200, so the current voltage value is 2200W.

Alles nach folgendem Schaltplan verschalten (Pzem-004t Module müssen mit 5V Spannung versorgt werden, nicht sichtbar auf dem Schaltplan). Route one of the power output wires through the PZEM-004T core and connect the output wires to the Sonoff Basic output. I have mine setup but am not getting any power readings - I’ve checked all the connections so not sure what to troubleshoot next? Many of the energy modules available, require internet connections to clouds, etc (ick), and are very expensive. Den Wemos und 1 Pzem-004t Modul wie im obigen Schaltplan verschalten (Es darf nur 1 Modul angeschlossen sein!You must set the address of the modbus_controller to the current address, and new_address of the on_boot lambda to the new one. That’s very unfortunate but I can assure you nobody will be able to help you properly if you don’t provide logs. I wanted to add energy monitoring to my home automation setup, without too much custom hardware, but it had to be relatively cheap. This module features a TTL serial data communication interface, you can read and set the relevant parameters via the serial port; but if you want to communicate with a device which has USB or RS232 (such as a computer), you need to be equipped with different TTL pinboard (USB communication needs to be equipped with TTL to USB pinboard; RS232 communication needs to be equipped with TTL to RS232 pinboard). Please be careful because the wiring between the 10 Ampere models with 100 Amperes is different, if a short circuit or a short circuit can occur in the electrical network.

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. The goal for this project is to make a DIY power meter using the PZEM-004T v3 to monitor your power consumption, and since IoT is the new norm for remote monitoring, we can also interface the power meter with an IoT dashboard through Wi-Fi connection using the Wemos D1 mini microcontroller to visualize the meter readings online where you can access it using your computer or smartphone.Run the wire through the circular sensor and you`re ready to start measuring the voltage, current, and power. After the above sketch program is uploaded to the Arduino board, open the Serial Monitor at Baudrate: 115200.
