About this deal

VV][scheduler:131]: Running interval 'update' with interval=60000 last_execution=153078 (now=213080) PZEM-004T Energy Monitor: The PZEM-004T is an integrated module designed for measuring electrical parameters in an AC circuit. It can measure voltage, current, power, energy, and other electrical parameters accurately. The sensor uses non-invasive current transformers (CTs) or current coils to measure the current flowing through a wire without the need for cutting or interrupting the circuit.

Cannot running on Windows 10 64bit. Even when i set its compatibility with any Windows options. Also even when i… Note: 14 in the sending command is the alarm value (14 is a hexadecimal data representation, which converted to decimal is 20). What you should note is the power alarm value of this module is based on KW units, which means the minimum alarm value is 1KW, the maximum value is 22KW. Image re-used from https://www.instructables.com/id/Use-Homie-Firmware-to-Drive-Sonoff-Switch-Module-E/ Thanks @amayii0)Please note that metering chip inside of PZEM module is powered from AC side and it has to be on during startup of ESPHome device, othervise measure results won’t be visible. 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. 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?

I read 24 mV (resolution 1 mV) at 50 A indicated (50 mA secondary current), which makes the instrument appear as a burden resistance of 0.48 Ω (±4% resolution error at least).This module is equipped with 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 computer), you need to be equipped with different TTL pin board (USB communication needs to be equipped with TTL to USB pin board; RS232 communication needs to be equipped with TTL to RS232 pin board), the specific connection type as shown in Figure 2. In the below table are the communication protocols of this module: No

This data helps in identifying energy-hungry appliances, optimizing energy usage, and reducing electricity bills. i had the same issue as you all, then i figure out from the documentation: it’s supposed to be a uint16 as type, not int16 Thanks for the help. I’ve made the changes you suggested and am still running into issues. I’ve tried with and without count: 2, and with and without any of the timeout clauses. My boot time is up over 5 minutes and my entities are pictured below. Some are still 0 or unavailable.With logging turned on: [20:35:16][VV][scheduler:185]: Running interval '' with interval=10000 last_execution=145431 (now=155431) Wie speichert sich das im Wemo? Wird das überschrieben, wenn ich den Update? Meine Idee ist, dass ich den mal komplett resette und alles von vorne mach. 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.
