MQTT to Emonpi

[rosspeel]

I have been using an Emonpi for a few years that allows me to send MQTT data to it, I am not verse well with ESP Home, Is there any way of instead of sending MQTT data to Home Assistant but to a Emonpi instead?

Please remove the api: line from your configuration and add

mqtt:
  broker: !secret mqtt_host
  username: !secret mqtt_username
  password: !secret mqtt_password
  id: mqtt_client

This will push messages to your MQTT broker.

This is the pitfall: There is no ESPHome component to forward traffic via a serial line. If you ship the logger output via 4G to your server you have to parse it there. There is no read to use solution available for your edge case.

ok, I'm not very familiar with Hass. It looks like I need to study it in detail.

Hey, sorry to bother you again. Could you please tell me what hexadecimal commands should be sent to the JK02_32 version BMS to control the charge/discharge/balance switches? I am from China, and my English is not very good, so I have difficulty gathering information in English. I have looked at the code for a long time but still don't understand how it works.
