Anybody used PZEM-6L24 on esphome?
Thanks & Regards,
Aslam
Apparently yes according to a search of these forums. Best of luck defining your problem, describing it, and solving it.
I would also like to use a native in yaml input like in the case of pzem-004t
Modbus?
i have the following config.

Any idea how to fix this?
It’s quite problematic; I don’t think it’s possible without lambdas. I’ve reached this stage, but I don’t have the time or energy to refine it. The values are incorrect. A test rig needs to be built to verify this.

I created some helper scripts to use Lucas Hudsons PZEMPlus library with ESP Home. You can find it here: GitHub - p2baron/pzemplus-esphome: ESPHome external component for the PZEM-6L24 three-phase energy meter, using the PZEMPlus library.

Any idea how to make it ok?
Modbus?
if you are so smart, please make it work.
This error occurs when the PZEM-6L24 is not supplied with mains voltage.
What board are you using? What happens if you include the hardwareserial library in esp yml?
esp32 c3 mini.
how to include the hardwareserial library in yaml?
I think your trying to compile the idf core and not the Arduino core.
Is this in your yaml?

Is this question for me?
no, its from esphome new device and from GitHub - p2baron/pzemplus-esphome: ESPHome external component for the PZEM-6L24 three-phase energy meter, using the PZEMPlus library.
Known Limitations
Second point:
Not all function’s from Lucas his library are linked. ← this appears to be your problem. Raise a bug report in GitHub and get it fixed or examine the folder structure and copy the appropriate files yourself to there, and compile again. Look for other variants and forks of the code that may be more complete, or fork your own.
