How to add weather station (lemmy.world)

I still have trouble understanding how to add an MQTT device without YAML. It seems there's an elaborate GUI flow made to deal with this, so why is this so complicated?

I have MQTT messages coming in. Their topics are e.g.

wx/temperature wx/humidity wx/light_lux wx/rain_mm wx/wind_dir_deg

How do I tell Home Assistant to just add the bloody device, and let me configure units afterwards and not type out 600 lines of YAML manually?

What type of radio is the weather station using? Are you pulling the data using RTL_433?

[–] oz1sej@lemmy.world 1 points 5 days ago (1 children)

Yes, with a Raspberry Pi, and sending data to the MQTT server directly with rtl_433 and the MQTT option.
