GotShitDone

Intro

GotShitDone is a spring boot app which can send you a notification via Telegram when a device connected to a fritz!dect starts and stops working. It can handle as many devices as you want and the standby power consumption is configurable as well as the notification messages. The stop message includes the cost and power consumption for the last job.

Create your own Telegram bot

You have to start a Telegram conversation with @BotFather and create a new bot. The token for your bot has to be configured in the application.yml.

Build the app

Since it is a spring boot gradle project, you can build it with ./gradlew build. The executable jar file lies in build/libs/GotShitDone.jar and is ready to use with e.g. init.d. You just have to create a link to the jar.

Configuration

The configuration has to be in a config directory next to the jar file. It looks like this:

fritzbox:
  url: http://fritz.box
  user: admin
  password: "xxx"
  deviceConfigs:
    -
      name: "FRITZ!DECT 200 #1"
      standbyInWatt: 10
      waitInSeconds: 600
      startMessage: "Washingmachine running."
      stopMessage: "Washingmachine ready. Costs: {COST}, Consumption: {WH}."
      pricePerKwh: 0.28025
telegram:
  token: xxx
  botUsername: botusername
  allowedNumbers:
    - +49xxx
intervalInMS: 2000
logging:
  level.de.veltrus.gotShitDone.telegram.KnownChatIds: debug
spring.jpa.hibernate.ddl-auto: update
spring.datasource:
    url: jdbc:h2:./h2.database
    username: sa
    password:
spring:
    jpa:
        database-platform: org.hibernate.dialect.H2Dialect

waitInSeconds is the time the device has to use less power than standbyInWatt to send the stopMessage. The pricePerKwh is used to generate the {COST} in the stopMessage.

Authorization

When starting a telegram conversation with your new bot via /start you are asked to send your contact details. The numbers which are allowed to get notifications by the app can be configured with allowedNumbers. The chat ids are persisted in a h2 database which is located next to the jar file.
