3-phase power consumption measurement

[dynamicdave]

Hi Bart,
When I tried to use ESPeasy two or three years ago I couldn't get it to work with the PZEM-004T.
The situtaion might be completely different now,

Here's a link to a write-up I did about how I interfaced the PZEM to a Wemos D1 Mini via level shifters.

Need to write one function that will return 3 values

Here's a screen-shot of my simple dashboard. [ScreenShot186] I'm using a PZEM-04 module with a split-ring current transformer feeding into a Wemos D1 Mini flashed with Tasmota that transmits to Node-RED via MQTT (very similar to your system). Here's a screen-shot of the NR flow. [ScreenShot184] And here's the flow-code that uses a dynamic band changer for the Power-gauge. [{"id":"47ec6f8.e8c9b9","type":"ui_gauge","z":"f0f0fcca.cf3ac8","name":"","group":"900b126f.c721c8","order":2,"width"…

This is what the home page looks like in Tasmota for the PZEM.

To put your mind to rest, I actually have a number of devices flashed with Tasmota, for example some Sonoff Basic, S20s and S26s - as well as the Wemos I mentioned above.

EDIT: Just upgraded Tasmota to the latest version 12.2.0
