В данной статье я расскажу как добавить мониторинг ИБП в Home Assistant на примере CyberPower Value500EI.

У данной модели есть USB разъем для мониторинга состояния ИБП. Для мониторинга у CyberPower есть своя утилита под названием PowerPanel. Скачать ее можно с сайта производителя. У меня на домашнем сервере стоит Ubuntu 20.04, по этому я скачал PowerPanel for Linux 64bit (deb).

Подключаем ИБП через USB и устанавливаем PowerPanel:

 dpkg -i CyberPower_PPL_Linux+64bit+\(deb\)_v1.4.1.deb

После установки проверяем командой:

pwrstat -status

В ответ, если все нормально, должны увидеть примерно следующее:

    The UPS information shows as following:

    Properties:
            Model Name................... Value500EI
            Firmware Number.............. BZAB100.B31
            Rating Voltage............... 230 V
            Rating Power................. 275 Watt(500 VA)

    Current UPS status:
            State........................ Normal
            Power Supply by.............. Utility Power
            Utility Voltage.............. 224 V
            Output Voltage............... 226 V
            Battery Capacity............. 100 %
            Remaining Runtime............ 31 min.
            Load......................... 49 Watt(18 %)
            Line Interaction............. None
            Test Result.................. Unknown
            Last Power Event............. Blackout at 2022/09/13 23:53:27 for 7 sec.

В файле /etc/pwrstatd.conf настраиваем выключение компьютера через время после перехода на резервное питание или при разряде аккумулятора на определенный процент. Также можно настроить отправку E-Mail или выполнение произвольного скрипта. После изменения перезапускаем демона:

service pwrstatd restart

У меня настроено выключение сервера при разряде аккумулятора до 35%. Мой конфиг:

# The pwrstatd accepts four types of device node which includes the 'ttyS',
# 'ttyUSB', 'hiddev', and 'libusb' for communication with UPS. The pwrstatd
# defaults to enumerate all acceptable device nodes and pick up to use an
# available device node automatically. But this may cause a disturbance to the
# device node which is occupied by other software. Therefore, you can restrict
# this enumerate behave by using allowed-device-nodes option. You can assign
# the single device node path or multiple device node paths divided by a
# semicolon at this option. All groups of 'ttyS', 'ttyUSB', 'hiddev', or
# 'libusb' device node are enumerated without a suffix number assignment.
# Note, the 'libusb' does not support suffix number only.
#
# For example: restrict to use ttyS1, ttyS2 and hiddev1 device nodes at /dev
# path only.
# allowed-device-nodes = /dev/ttyS1;/dev/ttyS2;/dev/hiddev1

Далее в Docker необходимо установить контейнер, который будет парсить эту информацию и передавать в MQTT брокер:

docker pull dwinks/pwrstat_docker
docker volume create pwrstat_data
docker run -d -p 5003:5003 --name=pwrstat --restart=always -v /var/run/docker.sock:/var/run/docker.sock -v pwrstat_data:/data dwinks/pwrstat_docker

После запуска контейнера смотрим его ID из списка:

docker ps -a

Переходим в консоль контейнера:

docker exec -it a86d79a48027 bash

В контейнере нам нужно для удобства установить nano и отредактировать конфиг. Для это выполняем:

apt update
apt install nano -y
nano /pwrstat.yaml

В конфиге указываем IP адрес и порт MQTT брокера, частота обновления, имя и пароль MQTT.

pwrstat_api: # optional
  log_level: WARNING # optional
mqtt:
  broker: "192.168.0.24"
  port: 1883
  client_id: "pwrstat_mqtt"
  topic: "sensors/basement/power/ups"
  refresh: 5
  qos: 0
  retained: true
  username: "*****" # optional
  password: "*****" # optional, required if username specified
rest:
  port: 5003
  bind_address: "0.0.0.0"
prometheus:
  port: 9222
  bind_address: "0.0.0.0"
  labels:
    rack: "0"

Перезапускаем контейнер:

docker restart pwrstat

Проверяем работоспособность по ссылкам: http://192.168.0.24:5003/health и http://192.168.0.24:5003/mqtthealth. Не забудьте поменять IP на свой. Если все нормально, то мы увидим:

{"code":"SUCCESS","message":"OK"}

Отлично! Данные отправляются в MQTT. Теперь необходимо достать их в Home Assistant. Для этого создаем сенсоры:

mqtt:
  sensor:
    # UPS Sensors

      icon: mdi:rename-box

    - name: "UPS Last Power Event"
      state_topic: "sensors/basement/power/ups"
      value_template: "{{ value_json['Last Power Event'] }}"

У меня это выглядит вот так:

Так же я настроил уведомления в Telegramm при отключении и включении электричества.

- alias: "Уведомления - Питание от ИБП"
  mode: single
  trigger:
    - platform: template
      value_template: "{{ states('sensor.ups_state') == 'Power Failure' }}"
  action:
    - service: notify.me
      data:
        message: "Внимание! Проблемы с питанием, переход на питание от аккумулятора."

- alias: "Уведомления - Питание от сети"
  mode: single
  trigger:
    - platform: template
      value_template: "{{ states('sensor.ups_state') == 'Normal' }}"
  action:
    - service: notify.me
      data:
        message: "Питание восстановлено"

На этом настройка завершена! Спасибо за внимание 🙂
