Dorzucę od siebie przepis jak to zrobić w dockerze, oszczędzi to czasu na kompilowanie binarek na raspberry pi i umożliwi provisioning malinki jakimiś skryptami :slight_smile:

  1. Zarejestruj się w Tauronowym e-Licznik, aktywuj HAN, uzyskaj ID licznika i jego klucz szyfrujący
  2. Zaczynamy od tego, że malinka posiada czystego RaspiOS (Raspbian?)
apt update
apt upgrade
dpkg-reconfigure tzdata
reboot
  1. Instalujemy dockera
sudo apt-get remove docker docker-engine docker.io containerd runc

sudo apt-get install     apt-transport-https     ca-certificates     curl     gnupg     lsb-release vim htop ncdu mc

curl -fsSL https://download.docker.com/linux/debian/gpg | sudo gpg --dearmor -o /usr/share/keyrings/docker-archive-keyring.gpg

echo   "deb [arch=armhf signed-by=/usr/share/keyrings/docker-archive-keyring.gpg] https://download.docker.com/linux/debian \
$(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null

apt update

sudo apt-get install docker-ce docker-ce-cli containerd.io docker-compose
vim /etc/docker/daemon.json

{
  "log-driver": "journald"
}

systemctl restart docker.service
  1. Tworzymy skrypty do autostartu kontenerów dockerowych
mkdir /etc/docker/compose/wmbusmeters -p
vim /etc/systemd/system/docker-compose@.service

  1. Konfigurujemy wmbusmeters
vim /opt/wmbusmeters/etc/wmbusmeters.conf

vim /opt/wmbusmeters/etc/wmbusmeters.d/domek
name=domek
type=amiplus
id=id_licznika
key=klucz_licznika
  1. Uruchamiamy wmbusmeters
systemctl start docker-compose@wmbusmeters
systemctl enable docker-compose@wmbusmeters
  1. Zostaje nam obserwować na MQTT czy pojawiły się odczyty z licznika :slight_smile:
  2. Konfiguracja Home Assistanta:
sensor:
  - platform: mqtt
    name: "Licznik domek Energia pobrana"
    state_topic: "wmbusmeters/85021882"
    unit_of_measurement: "kWh"
    value_template: "{{ value_json.total_energy_consumption_kwh }}"
    json_attributes_topic: "wmbusmeters"
    state_class: total_increasing
    device_class: energy
  - platform: mqtt
    name: "Licznik domek Moc pobierana"

    json_attributes_topic: "wmbusmeters"
    state_class: measurement
    device_class: energy
  - platform: mqtt
    name: "Licznik domek Ostatni odczyt"
    state_topic: "wmbusmeters/85021882"
    value_template: "{{ value_json.device_date_time }}"
    json_attributes_topic: "wmbusmeters"

Drobny update, czasami licznik nadaje zera, albo wmbusmeters czyta zera z telegramu licznika. Totalnie to zaburza później widok energii w HA.

Rozwiązaniem jest filtrowanie zer i ponawianie poprzedniego odczytu jako aktualnego.
Mądrzejszy o to doświadczenie, musiałem wywalić historię encji związanych z licznikiem i zbierać historię od nowa (czyli jestem wczorajszy dzień w plecy)
