inverter+ BMS

[fastvd]

Greetings. I have an esp32 board that works with jk-bms via modbus with the following firmware:
github://syssi/esphome-jk-bms@main

and also your great project i have successfully connected my POW-HVM10.2M inverter on separate esp32 board...

the idea is elementary: to control the inverter and bms from one esp32 board...

I seem to have combined the code of 2 firmwares, soldered everything correctly, but in the logs I get errors on the BMS part (the data from the inverter is fine)

here is my code:

substitutions:
name: bms-home
device_name: "powmr-inverter"
node_name: "PowMr Inverter"
node_id: powmr_inverter
inverter_tx_pin: GPIO1
inverter_rx_pin: GPIO3
inverter_voltage_offset: "0"

bms_tx_pin: GPIO16
bms_rx_pin: GPIO17

pzem_tx_pin: GPIO9
pzem_rx_pin: GPIO10
pzem_voltage_offset: "1"
pzem_current_offset: "0.04"
update_interval: 30s # Minimum 10s recommended to avoid duplicate command errors
select_skip_updates: "2"
pzem_update_interval: 6s # Needs to be 1/5 of update interval because of smoothing filter on pzem readings

This is a perfect idea. I tried to combine these projects, but there were also errors. I would really like to have such an implementation
