● HA작업) ESPhome esp32 ct-clamp 에너지미터 HAOS에 설치 설정하기
ESP32 개발 보드, 와이파이 + 블루투스, 초저전력 소비, 듀얼 코어 ESP-32S ESP32-WROOM-32D/32U, ESP 32 확장 보드
•WiFi+Bluetooth Module: E5P32-WROOM-32
•Specifications. HW-395(GP2102)
•Pin: 38Pin
•lnterface: Type-C
구입제품
1) esp32 cp210x 윈도우 com port 연결용 드라이브 다운로드 연결작업
https://www.silabs.com/developers/usb-to-uart-bridge-vcp-drivers?tab=downloads
c:\Users\shimss\Downloads\CP210x_Universal_Windows_Driver (20230826_1900_32).zip
장치 관리자에 연결확인 > 케이블과 USB 에 연결 포트를 찾아 연결합니다
HAOS에서 esphome으로 이동 > newdivice >>
적당한 이름을 주고 >> 다음
device 선택 > esp32
다운로드 준비
다운
install > 다운로드한 파일 선택 install
boot를 누르고
install > 퍼센트표시 되면 boot 버튼을 떼고 기달립니다.
3점 메뉴에서 disconnect 하고 종료
ESPHome 화면에서 >> log 확인
ESPHome 화면에서 >> edit > install 다시 wifi 조건으로 진행 합니다
기본적으로 기존에 wifi / password 설정을 1번째 설치시
/config/secrets.yaml 에 사전 설정해 놓아야 합니다,,,,저는 기본으로 1번이후 설치로 자동연결됨
IP Address : 192.168. 0.74
를 확인하여 edit 하여 고정ip로 변경 진행 합니다
기존
다음을
추가하자
edit 후에 다시 install 을 wifi 로 진행 합니다.
연결 성공 입니다
2단계로 esphome에 주변 기기를 연결 hardware 구성 합니다
- ct-clamp를 연결 진행 합니다
edit 하여

실제 측정치와 조정 합니다
- calibrate_linear:
- 0.0 -> 0.0
- 0.1146 -> 0.1146
일때
전체 로드 전류기준으로 실측치를 알아야 합니다
배전반에 전류 측정 장치를 물려 전류값을 측정 합니다
( 관리사무소에 연락 2~3번 측정하여 변경 하세요 )
높은 대역과 낮은 전류의 측정의 차이가 이있습니다
배전반에 전류 측정을 하여
- calibrate_linear:
- 0.0 -> 0.0
- 0.1146 -> 4.8
로 설정 사용중입니다
주) 선풍기의 소비전력 37W 낮은 전력사용은 현제의 ct-clamp의 규격에 맞지 않음
주) 낮은 전류의 값 반영이 상이합니다.
