So right now I have the following in my configuration.yaml:

Per the end of this month, the tariffs for energy and gas will change for me, since that will be the end of my contract. I was wondering though, once I change the input_numbers to their new prices what would happen. As you can see I calculate monthly and yearly prices as well, but those should ‘remain’ the same, since obviously the associated costs are with the old tariffs.

If changing the input_numbers would change all historical data as well, then I would like to ask you all how you guys handle this ‘problem’ with changing tariffs every year (or more often if you have a variable price contract).

[edit]
To clarify what I want to achieve: I want to change the input numbers (or create new ones?) and make sure that from that day onward the new prices are used, but that all historical data is calculated with their former input numbers… so to speak.

[Jonah1970 (Mark)]

Your setup seems very complicated compared to mine, you have entities to calculate current/previous day energy and cost, current/previous months energy and cost, and current/previous years energy and cost. This is then all repeated for gas.

If you used your daily energy/gas entities in the Home Assistant Energy Dashboard then all this gets calculated for you automatically and stored in the statistics history. I believe that this would also overcome any issues associated with changing the tariffs assuming you did this at the end of the day before the tariiff changes occur.

I don’t have gas but the following shows how I have the Energy Dashboard configured for electricity monitoring:

I only need to specify the entities for daily energy usage and cost and everything else is calculated automatically as below for the current year:

This seems very accurate and always matches my bills to within a small fraction of a percent.

Is there a reason why you cannot use the Energy Dashboard?

@Jonah1970

Am I to understand your energy provider billing is calculated 1st of each month? Which would be the only way I can see dashboard depicting usage close to said provider’s numbers. My issue has always been dashboard monthly numbers are based on 1st of month through end of month. Where as my provider bills 16th of month through 15th of following month.

Also, it would be helpful to see your “Energy Cost Today” code.

[Jonah1970 (Mark)]

Hi, yes I do get billed per calendar month so understand how this could be a problem in your situation (maybe you could ask your provider to change your billing date).

As requested, please find my template sensor for “energy cost today”:

energy_cost_today:
  friendly_name: Energy Cost Today
  unit_of_measurement: £
  value_template: "{{ (states('sensor.energy_usage_day_std') | float * states('input_number.std_tariff') | float / 100.0) | float + ((states('input_number.standing_charge') | float / 30.0) | float ) | round(2) }}"

There is a slight assuming in the above that assumes a month has 30 days i.e. the monthly standing charge (currently only £3.70) is divided by 30 and added to electricity cost for the day.

Of course the reason for doing this is because the Energy Dashboard can only use a rate in its calculation and there is currently no facility to enter a standing charge.

[Jonah1970 (Mark)]

Hi, you need to setup the energy manager dashboard as explained below:

Energy Management in Home Assistant

Obviously for this to work you will at least need a suitable sensor that is monitoring your energy usage.
