Most Nordpool cost savings by comparing sequences of high energy prices to previous sequence when heating house continuosly

Automating heating the house is kind of hard when considering hourly prices

Here I try explaining the concept of heating my one family house with 2 air heat pumps, central water heating system with multiple smart valves added to radiators.
All other concepts have been concentrating on heating only on when energy price is cheap, like heating x most cheap hours a day.

My approach to heating is that I want to live in pleasant environment, have minimal impact on house climate while minimizing energy cost. I do need to heat house all the time especially when temperature outdoors is -25°C.

As most, I used to cut with automation “high” electric prices of the day as it easy to find those hours. But then I started thinking other way around: if I would find the highest difference between X sequential prices and X sequential prices before that, so the sparing the money is the most. Imagine that you look up the chart

and see that on the morning before prices go high, you could warm up the house a bit more and then cut the heating. And do it automatically on every occasion on the sequence width of your choosing.

So I did come up a concept and implemented it on my system on which I could maybe spare more money while finding more those high peak/ highest prices of the day:

  1. find X hours sequence that is most expensive than the previous X hours sequence
  2. use same algorithm to find X hours sequence before and after the most expensive X hours sequence to further maximize sparing money
  3. heat more before the expensive hours sequence, maybe set 1-2 degrees more to heating elements
  4. set the heating off/ minimal on the expensive hours sequence

Concept premises:

  • have a list of today prices of energy, price per hour (24h per day)
  • I’m using norpool which has attribute for “today” prices on list

The basics of the system is the sensors which I use in my automations like one below (the checking if nordpool is available is not necessary, but it is good to output recent value when the cloud value is not available). The /config/configuration.yaml -file has an entry

template: !include_dir_merge_list template/

and the following code of sensors is in the “/config/template/template_sensor.yaml” -file:

Automations

  1. Main HVAC automation is checking outside and inside temperatures, weather forecast and does changes to heating/ cooling by those sensors.

  2. Automation check if it is time to put on energy savings:

  1. Main energy savings HVAC automation is checking if it is time to preheat/ precool house more if the “high price” event is about fire up. After the event is on, it will cut the heat on the house by setting built in + or - to predetermined setting corresponging to outside temperature. That is, if the ouside temperature is +20 and over I set cooling +3 and if the outside temperature is +10 and under I set heating -3.

Main energy savings HVAC automation of mine below as an example. Sorry about the mixed use of Finnish language and the English, historical reasons. I think it is more helpful to see the automation still than not seeing it.

Had a stupid error in the template-sensor, did not check if fhe most valuable savings hour is too near the start of the day

{% set firstHour = (0+numberOfSequentialHours) %}
{% set lastHour = (states('sensor.nordpool_price_most_savings_sequential_hours_energy_today') | int (4) - (2*numberOfSequentialHours)) %}

{% if firstHour < (lastHour-numberOfSequentialHours) %}

or end of the day .

{% set firstHour = (states('sensor.nordpool_price_most_savings_sequential_hours_energy_today') | int (4) + (2*numberOfSequentialHours)) %}
{% set lastHour = 24 %}
