HOMEASSISTANT

HomeESP

HA ima zelo dobro podporo za ESP krmilnike. ESP32 ali ESP8266 lahko programirate s HA-jem z nekaj kliki. Za komunikacijo z ESP krmilniki potrebujete: ESPHome.

ESP32-Home

  • ESPHome omogoča enostavno ustvarjanje prilagojenega firmwarea za ESP32/ESP8266 z uporabo YAML konfiguracij, ki opredeljuje senzorje, stikala, LED in druge aktuatorje ter zagotavlja lokalno zbiranje in posredovanje podatkov v omrežje.
  • Integracija z Home Assistantom poteka prek ESPHome integracije: napravo se flasha (OTA ali USB), dodamo v vmesnik Home Assistanta in pridobimo entitete (sensorji, stikala, priklopi na naprave), ki jih je mogoče uporabiti v avtomatizacijah, scenah in nadzoru.
  • Prednosti so prilagodljivost, delovanje lokalno brez odvisnosti od oblaka, hitrejši odziv ter bolj dosledno spremljanje porabe energije in stanja naprav; omogoča pa tudi enostavno ustvarjanje avtomatizacij in vizualizacijo stanja v pametni hiši.

Integracija v Home Assistant

  1. ESPHome Builder -> [+New Device]

Postopek integracije ESP32 krmilnika v Home Assistant (na kratko, kronološko)

1) Priprava in načrtovanje

  • Pripravite ESP32 razvojni modul, USB kabel in računalnik ali že odprt Home Assistant z ESPHome dodatkom.
  • Preverite, ali imate dostop do omrežja (Wi‑Fi) in ali lahko zapišete ime omrežja ter geslo.

2) Programiranje ESP32 z ESPHome

  • ESPHome namestite (prek Home Assistant add-ona ali lokalno na računalniku).
  • Zaženite ESPHome GUI ali CLI in ustvarite novo napravo:
    • Vnesite ime naprave, platformo ESP32 in tip plošče (npr. esp32dev).
    • Vnesite omrežno SSID in geslo.
    • Dodajte potrebne module (api, ota, logger) po potrebi.
  • Flashajte firmware na ESP32:
    • Če uporabljate OTA: povežite napravo v omrežje, izberite OTA pri postopku nalaganja in poženite nalaganje.
    • Če uporabljate USB: povežite ESP32 preko USB in izberite Flash (USB) v ESPHome GUI ali uporabite esphome run ukaz.
  • Preverite v ESPHome dashboardu, da je naprava online in dodeljena IP naslovu.

3) Integracija v Home Assistant

  • V Home Assistant pojdite na Configuration → Devices & Services → Add Integration → ESPHome.
  • Vnesite ali izberite IP naslov ESP32 naprave (ali omogočite samodejno odkrivanje).
  • Po uspešni integraciji bodo entiteti (npr. senzorji, stikala) na voljo za avtomatizacije, scenarije in nadzorno ploščo.

4) Preverjanje in uporaba

  • Preverite, ali se nove entitete pravilno prikažejo v Lovelace pogledu.
  • Ustvarite enostavno avtomatizacijo ali sceno za testiranje funkcionalnosti.

6) Dodatno

  • API ključ ni običajno potreben za standardno integracijo ESPHome z Home Assistant; ESPHome uporablja svojo API biezo in odkrivanje v omrežju. Če potrebujete bolj zapletene integracije ali REST klice, uporabite ustrezne avtentikacije po potrebi (npr. Home Assistant Long-Lived Tokens zunaj običajne ESPHome integracije).

PWR Metere

V ESPHome sta dve funkciji, ki lahko merita pogostost pulzov:

  • pulse_meter in
  • pulse_counter

Pulse_meter je imel v zadnjem času nekaj težav in je občasno pokazal neverjetno napačne podatkje, zato je bolje, da v tem primeru uporabljamo kodo prejšnje različice te funkcije:

Wireless uploading

ESP module lahko sprogramirmo tudi preko WiFija. Opazil sem, da se povezava ne vzpostavi vedno… mislim pa, da je težav manj, če pred programiranjem dostopimo na server tega modula in šele nato sprogramiramo:

1. ESPHome -> Module -> Visit ...
2.              └> Edit -> Install

SSH & TERMINAL

Za povezavo SSH in uporabo terminala na HA-ju je dobro uporabljati: Advanced SSH & Web Terminal18.0.0

Ne pozabi nastaviti uporabniškega imena in gesla v konfuguracijski datoteki in shraniti nastavitve ter nenazadnje tudi ponovno zagnati terminal.

Za namestitev aplikacij lahko uprabljamo upaz kot na primer:

apk add ranger
