Question

This QuickApp calculates the cheapest prices for using appliances based on the hourly Tibber energy prices. 
This QuickApp is especially useful for appliances (like charging your car and washing the dishes) that need to run once a day, within a timeframe and during some hours. 
You can use more than one instance of this QuickApp if you need more than one appliance to start in the cheapest hour but not within the same timeslot. 

 

Tibber today and tomorrow prices
The tomorrow prices are available from 13:00 hour. 
If the tomorrow prices aren't available yet and the timeslot is (partially) tomorrow, a temporary calculation and start-stop plan is made with the today prices, until the tomorrow prices are available. 
If the start time plus duration is (partially) tomorrow, for example start time 18:00 and duration 7 hours, the calculation can be made from 13:00 hour when the tomorrow prices are available.

At 04:00 the binary switch will turn ON and at 07:00 the binary switch will turn OFF. 

You would still have to create a script, triggers by this binary switch, to actually turn on the charging of your car, or turn on the dishwasher. 

 

 

IMPORTANT
This QuickApp needs the Tibber Monitor QuickApp to run on your HC3. 
It is important to synchonise this QuickApp with the timing of your Tibber Monitor QuickApp. 
This QuickApp works at its best, if you setup the interval with the intervalOffset just after the Tibber Monitor runs. 
If you Tibber Monitor runs at 5 minutes (300 seconds) after the whole hour, run this QuickApp 5 minutes and 10 seconds (310 seconds) after the whole hour to be sure to get the prices from Tibber Monitor. 
This QuickApp runs every whole hour to turn the switch on and off. If it is time to get the prices from the Tibber Monitor QuickApp, this QuickApp runs every whole hour plus the seconds set in the intervalOffset. 

 

QuickApp logics

  • onInit()
  • getQuickAppVariables() 
  • createVariables()
  • checkPrice()
  • missionControl() 
    • If tibberChild0000 (Tibber Monitor Child devicenumber for "Today 00:00") doesn't exists --> disable QuickApp
    • If current hour is hour to start --> turn the switch ON 
    • If current hour is hour to stop --> turn the switch OFF
    • If current hour is 13:00 (tomorrowPrices) --> checkPrice() to check the prices again to calculate with the tomorrow prices and to plan a new start and stop hour
    • If current hour is the end of the timeslot --> checkPrice() to check the prices again to plan a new start and stop hour
    • updateLabels() every whole hour
  • missionControl() (see above)
  • etc

I like the idea Eddy for various purposes. With Tibber and Solar panels this can also be user to turn airco on when prices go negative. so the need to cool down the house after there production hours of the solar installation is reduced. Turning on dish wassers and wasching machines is only possible with modern/smart devices. Most of my equipment is to young to replace and to old to be/turned to smart.

  • Indeed @Langedijk for a lot of users the dishwashers and that kind of appliances aren't smart yet (because too young to replace). I have a dishwasher that connects to WiFi, but only when you turn it on. If still turned off, nothing will happen. 

     

    You could give the airco a boost, but this quickapp only calculates the cheapest time within that timespan in comparison to the other prices. That doesn't have to be  a cheap price, it could also be less expensive.

    I have uploaded a new version (in the first post) with a bug solved (timeslot end was greater than 23 hours, it was one hour too many)
