Þessi kóði er ætlaður fyrir ESPHOME og les snjallmæla frá Veitum, bæði rafmagn og hita með því að sækja gögn frá P1 tenginu. Home Assistant er með ESPHOME intergration og því auðvelt að bæta lesaranum þar inn eftir að hann hefur verið flassaður.
Kóðinn er að mestu byggður á esphome-p1reader en það var ekki stuðningur við hitaveitumælinn og tékksummu tékkið (crc) var ekki að virka rétt. Ég tók því út crc og breytti því einnig hvernig OBIS kóðinn er lesinn svo einfaldara væri að bæta inn nýjum OBIS. Búnaðurinn, rafrásin, sem les frá P1 tenginu er svipaður því sem er hjá esphome-p1reader og einnig er hægt að nota SlimmeLezer+ dongle.
git clone https://github.com/gardart/veitur-meter-reader.git
esphome run veitur-meter-reader.yamlÞegar búið er að tengja lesarann við p1 tengið á ISKRA mælinum þá ætti loggurinn að sýna þegar hann sendir boð um að sækja gögn og sömuleiðis gögnin (OBIS kóðana) sem mælirinn skilar. Hitaveitumælirinn (Sharky) er tengdur þráðlaust við ISKRA mælinn og sýnir hitaveitugögnin með OBIS forskeytinu 1-0. Hann birtir því sínar mælingar sem undirmælir við ISKRA. Ef engin hitaveitugögn birtast þarf mögulega að biðja Veitur um að virkja það.
