    This manual will show you how to acheive "remote" wmbus metering.
ESP stick

You will need to grab NodeMCU V2 development board and CC1101 radio transceiver.

Feel free to use something like this:

ESPHome configuration

Use config esp_wmbus.yaml.

In this configuration, ESP stick will stream all received telegrams to wmbusmeters running as your Home Assistant addon.
HA Addon Configuration

Current wmbusmeters addon configuration is somehow broken.

I created a pull request fixing this issue, but it's a breaking change for current users.

wmbusmeters/wmbusmeters#838

For now, you can use my forked repo.

Go to Home Assistant → Settings → Add-ons
Click ADD-ON STORE
Upper-right corner click 3 dots → Repositories
Add Repository https://github.com/KrzysztofHajdamowicz/wmbusmeters
Install wmbusmeters addon
Configure Your instance:

enable_mqtt_discovery set to true

conf:
