how to get values (MQTT subscribe?) and store into DB

Hello, first, big thanks for this project, working great. I'd like to store data from a BMS to a DB (already used for inverter data), but struggling how to do that. I did a scan of MQTT topics with MQTT.fx tool, and if I subscribe to f.i. homeassistant/sensor/jbd-bms-uart/jbd-bms-uart_discharging_power/config, payload data are like below, but no value. How can I get them? Thanks!
{"dev_cla":"power","unit_of_meas":"W","stat_cla":"measurement","name":"jbd-bms-uart discharging power","stat_t":"jbd-bms-uart/sensor/jbd-bms-uart_discharging_power/state","avty_t":"jbd-bms-uart/status","uniq_id":"ESPsensorjbd-bms-uart_discharging_power","dev":{"ids":"c8c9a30bf3fd","name":"jbd-bms-uart","sw":"esphome v2022.12.4 Jan 22 2023, 18:37:42","mdl":"nodemcu","mf":"espressif"}}
If your BMS is attached the component should request measurements periodically and publish these values as sensor state. You have to subscribe to all state topics you are interested in. You could use a tool telegraf to pass the data into a influxdb.
Ah, I had mqtt and broker commented out, just used the api :) Thanks for kicking me to check! Solved.
I had to enable mqtt in the yaml.
