Hi, could I please have some advise to how to “read” / “see” values in esphome/homeassistant?
I have the PZEM platform showing V, A, Hz etc… correctly.
Now I have connected a real MODBUS RTU to my esphome and I off course get strange values every second. I would like to see the RAW serial data that gets received to see if I can translate that to sensors in HA.
The MODBUS values come from a solar inverter.
I really have googled any topic about modbus / esphome but it is VERY SCARS…
My config:
uart:
tx_pin: D1
rx_pin: D2
baud_rate: 9600
stop_bits: 1
And this give me CORRECT values when I use a real PZEM (of course):
- platform: pzemac
update_interval: 1s
current:
name: "${esp_name} A"
voltage:
name: "${esp_name} V"
power:
name: "${esp_name} W"
unit_of_measurement: W
id: "${esp_name}_W"
icon: mdi:flash-outline
frequency:
name: "${esp_name} Hz"
power_factor:
name: "${esp_name} Pf"
energy:
name: "${esp_name} Wh"
Main question: How can I see the RAW serial data on pin D1 / D2?
I might then be able to use:
EDIT: I also have a hard time understanding how to use above link …
Currently with the MODBUS connected to pzem config I get totally weird values :-):
