냉장고에 부착한 날씨 알리미들

아래쪽에 위치한 전자잉크 표시기는 마트에서 가격표로 사용하는 ESL(전자 가격 표시기) 인데 홈어시스턴트에서 날씨정보를 보내서 사용하고 있습니다.

준비물

Gicisky 4.2인치 bluetooth ESL tag (4~5만원)
ESP32-S3 N16R8 보드 (1만원)
USB C 케이블과 연결할 컴퓨터
Home Assistant
무선 홈 네트워크 (공유기)
USB 충전기와 케이블
양면테이프 또는 자석

BLE ESL용 AP 만들기

ESP32-S3 보드를 PC 에 연결하고 아래 펌웨어 설치 페이지에서 BLE only AP 를 선택하고 설치합니다.
브라우저에서 시리얼 포트로 바로 연결하고 펌웨어 설치 진행. 문제가 생길 경우 장치관리자 등에서 ESP32 시리얼 포트를 확인해야 합니다.
설치 완료 후 ESP32가 받은 IP로 접근해보면 아래와 같은 화면 확인 가능합니다.

몇분동안 기다리면 ESL tag 가 인식되고 기본 컨텐츠 적용할 수 있습니다.

기타 설정이나 AP 펌웨어 OTA 업그레이드 기능 등등이 있으니 사용해보면 됩니다.

홈어시스턴트에 OpenEPaperLink 설치

홈어시스턴트 HACS 에서 OPenEPaperLink 찾아서 설치하면 됩니다.
설명 및 소스코드는 아래 링크 있습니다. 설치/재부팅 후 통합구성요소에 추가 해주면 됩니다.

날씨 정보 만들기

날씨 정보 표시하기

다른 사용자가 만든 코드를 참조해서 수정해서 사용중입니다.
원본은 아래 링크에 있습니다.
https://github.com/chunkysteveo/OpenEPaperLink-HA-Weatherman

저는 아래와 같이 수정해서 사용중입니다.
기본적으로 날씨는 담다날씨에서 가져오고, 풍향 풍속은 met 에서가져오고 이런식으로 짬뽕되어 있습니다.
이부분이 좀 귀찮은데 개인화가 필요한거라 한번 노가다 하는 방법밖에 없습니다.
표시하고 싶은 시간대, 간격, 날짜, 표기법, 풍향풍속 유무, 기타 문자열 표기 등등..

그리고 짧은 날씨 정보를 문자로 표시했는데 이건 다른 센서로 기상청 데이터 긁어온거라 생략하겠습니다.
( sensor.today_home_weather 와 sensor.today_weather_txt 항목 )

자동화 편집 시 yaml 모드로 할것 (변수가 있어서...)
위 github 에서 큰 변경점으로는 target 에 device_id 를 넣어줘야 합니다.
개발자 도구에서 OpenEPaperLink: Draw Custom Image 선택 -> 기기 에서 ESL 태그 선택 -> YAML 로 변경 해서 확인하면 됩니다.
target:
device_id: bbb79065b21976e867755ad10f1e8b6f

configuration.yaml 추가

홈어시스턴트 templete.yaml에 아래와 같이 추가해서 10분마다 날씨 데이터 갱신 시키고 있습니다.
물론 configutaion.yaml 에서 templete.yaml 이 추가되어 있죠.

# Bundle up all the data to send over to Weatherman.
# Will auto-detect the weather integration entity to use.
# If that doesn't work, set the value for the forecast_entity variable manually.

험난한 산을 넘고 요렇게 정보를 가득 채운 날씨 알리미 창을 만들었습니다.

사담을 더 붙이자면 7인치 제품 사고싶은데 너무 비싸더군요.
openepaperlink 디스코드에서 보면 국산 solum 제품 중고로 구해서 많이들 쓰더라구요. 펌웨어도 다시 라이팅 하구요.
AP는 esp32-s3 + esp32-c6 로 만들구요.

아니면 타오바오에 hanshow(汉朔) 제품이 중고로 조금 있던데, 요녀석도 호환 펌웨어 만들어 놓은게 조금 있더라구요.
그런데 펌웨어 올리려면 부숴서 뜯어서 펌웨어 라이팅 위치 확인하고 뒷판 구멍만 살짝 뚫고 포고핀 만든거로 라이팅 하더랍니다.
한두개 쓰기에는 좀 안맞고 대여섯개 만들어야 하는데.... 어렵습니다. 나중에 도전해봐야겠어요.
