[P102] Howto get all 6 returned values (device: PZEM-004Tv30-Multiple)

[net1957]

PZEM-004T -(V3.0) can return 6 values, but one device in ESPEasy can only return 4

On older versions of the plugin, you could add 2 entries for the same PZEM, but in this latest version it's not possible. The "Address of PZEM" can't be reused.

How can I retrieve all 6 values ?

• Voltage
• Current
• Power
• Energy
• Power Factor
• Frequency

I respond to my self. Perhaps it could help another user!

It work as expected, but you have to set the address of the pzem. If you give the address 1, you can add a second entry with the same address to get the 2 others values.

about the cabling : You can directory connect the pzem to an esp32 with 3.3V and not 5V as marked on the pzem. This power entry only power the RX and TX leds and the 2 photo-couplers. So no need for level shifting! it is much simpler .

Thanks for this great software.
