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

Product Information

VV][scheduler:131]: Running interval 'update' with interval=60000 last_execution=93078 (now=153079) May need to use external transistors to drive multiple devices on one bus due to GPIO current limitations)

PZEM004T Energy Monitor with esphome How to use PZEM004T Energy Monitor with esphome

As most parts are connected to high voltage AC it is recommended to fit the hardware in a solid enclosure. Software configuration ~ Alles nach folgendem Schaltplan verschalten (Pzem-004t Module müssen mit 5V Spannung versorgt werden, nicht sichtbar auf dem Schaltplan).

Application Discussion:

Below my .yaml config. Just add new device to EspHome paste this config and generate .bin substitutions: Make sure the PZEM device is connected to the 230V AC power! The 5V pin only powers the optocouplers, not the actual chip. In the example program to access or interfacing the PZEM-004T V3.0 module using this Arduino, we use the following library :

Depending on the specific PZEM sensor and current coil used, calibration might be necessary to ensure accurate readings. Calibration factors or correction values can be stored in the Preferences. 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.Pzem-004T Module berührungssicher verbauen, Ich habe die Wechselspannung-Seite bis zu den Optokopplern mit Schrumpfschlauch vor versehentlichem berühren geschützt (neuere Modelle sind nun in ein Gehäuse verbaut)
