Let's Control It

Hi,
I have a question for the members of the forum if communication with PZEM-017 works for anyone. I tried it with the P-102 PZEM-004Tv30-Multiple plugin but it doesn't work (PZEM-004T v3.0 works for me).
Thanks

EDIT: I use modified PZEM-017 with TTL communication behind the optocouplers. Communication with the PZEM application works.
. . .
EDIT2: Tasmota works.
.

You can try P078 Eastron Modbus plugin, to see if it matches any of the devices there, as it's using the Modbus protocol, but I can't verify for myself, as I don't own any matching device.

Communication seems to work, but the communication protocol does not fit.

The structure of modbus registers is different for AC and DC meters.

So we need to extend the plugin to also support the extended/new commands.

That's right, Tasmota plugins could be an inspiration

The plugin needs to be reduced because pzem-017 has fewer registers.
Is there any news?

Any news on the PZEM-017 plugin? It's an excellent DC voltage and current meter. I use it to measure the output from the photovoltaic panels of my power plant (Tasmota so far).
