how can we use this PZEM004T Energy Monitor with esphome and home assistant ? [image] olehs/PZEM004T Arduino communication library for Peacefair PZEM-004T Energy monitor - olehs/PZEM004T [image] PZEM-004T Maximum 100A AC Multifunction Power Monitoring …

As per my understanding, It requirs the AC side of the connections (Phase and Neutral) active to measure the readings.

[image] Waxedout: Based on what I’ve read in this thread, is it safe to say that the PZEM-004Tv3 cannot be used unless you connect it directly to an A/C power source? Yes, that’s due to the fact how AC power metering works. :zap: If you are only interested in current and don’t need power rea…

2 years later this works great. I don’t have a display, but the measurements works. Also my PZEM module had V1 written on the board, but on the instruction that come with appeared that includes frequency and power factor. The original V1 didn’t included those. So for who like me is buying modules …

I would like to share my pzem implementation as well. It is modified PZEM-004T version which is based on the modification done by the user HWCave from Github. TheHWcave/Peacefair-PZEM-004T-: reverse-engineered schematics and interface software (github.com) . The modification and resulting PZEM-004T …

Hi, I’d like to use PZEM004T 100A V1.0 for power metering with NodeMCU in ESPHome. I have connected it but no data received. Only one led blinks on sensor. [image] Here is my code. What is wrong with this? uart: tx_pin: TX rx_pin: RX baud_rate: 9600 sensor: - platform: pzem004t cu…

if you are trying this in your test bench make sure the Power Side (Phase & Neutral wires) is also connected to respective terminals. Without that, you will not get any reading. In order to identify the current measurement, you should pass through only one wire of your load. Also as orange-assistant…

Did you experience any problems with extending the wires?

[image] Mr.ToR: I’m using a cheap bidirectional 5V-3V digital converter module to power the ESP01 with 5V and also to allow bidirectional communication with 5V serial TTL with PZEM. Sorry, maybe I don’t understand something, but why not just take 5V directly from usb charger? You supply 5V th…

Hello! To synchronize the accumulated energy value of the PZEM with my home electricity meter, I use the OFFSET function. Is it possible to make this value entered from the Home Assistant and saved when the power is turned off? My code: sensor: - platform: pzemac current: name: "Curr…
