Whether you are a maker, student, researcher, developer, product creator, or entrepreneur, there's a lot to learn and develop in robotics, internet of things (IoT), automation, artificial intelligence (AI), and STEAM education. Ich habe die Variante mit den Tasmota Befehl selber noch nicht getestet, weil mit dem Herstellertool kann man super auch kontrollieren, ob die Adressierung stimmt. Simply power the board with a power supply (or you can use the AC source you are measuring) and connect the circular sensor to the board. Run the wire through the circular sensor and you`re ready to start measuring the voltage, current, and power. The circuit also comes with a TTL to USB adapter wire for easy connection to a computer or microcontroller. At the beginning of the program, the Preferences library is initialized with a unique namespace, which will be used to store the configuration settings. IMPORTANT: If using the connections as following, the communication works in all cores due to TASMOTA using hardware serial. If the user wants to use other GPIOs for communication, TASMOTA will emulate a serial interface using software serial. This feature does not work using core 2.3.0 due to insufficient RAM. To use the software serial feature, you must use a core version of 2.4.2 or greater.

Mit der Software kann übrigens das Gerät auf Funktion überprüft und auch Kalibriert werden, wenn nötig! VV][scheduler:131]: Running interval 'update' with interval=60000 last_execution=93078 (now=153079) From what I gather the pzems are quite voltage sensitive. One works while connected to my pc usb, while doesn’t work when connected to ipad charger It can easily measure the output voltage of the USB port and the device operating current or load voltageThe only thing i hate of this little and cheap thing is that you can't have a simultaneous reading of data. 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.

You need to compile your own Tasmota firmware as none of the pre-compiled binaries have support for display and PZEM module. I’m trying to add a PZEM-004T with a direct USB Serial connection to my RPi using Modbus. I have been able to get entities to appear, however for some of my entities I keep getting unavailable and/or unknown errors. Energy Auditing: Power monitoring systems are valuable tools for energy auditors to assess energy usage patterns in residential and commercial buildings. The collected data helps auditors identify areas for energy conservation and recommend improvements. I too have a PZCT-02, which came with a PZEM-022, so it’s looking very likely that the input is 100 mA.include /* Use software serial for the PZEM * Pin 11 Rx (Connects to the Tx pin on the PZEM) * Pin 12 Tx (Connects to the Rx pin on the PZEM) */ 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 Adressiert sind sie auch, aber ich bin mir nicht sicher ob das geklappt hat. Wenn sie adressiert sind, funktionieren es nur noch, wenn alle drei angeschlossen sind oder?
