Hi,

I have klimalog which measure a temperature and humidity in different area. I catch his message by rtl_433 and temporary save to mqtt in topic by id.

I check this web MQTT Sensor - Home Assistant and well. I know how add specific sensor… but I don’t want add 100 sensors to my configuration.yaml. I would like when see specific new topic in specific channel mqtt, automatic add next sensor/(or i don’t know - add new fields to one big entity with all sensors). How i can do this?
