Hello Everyone.
This is my frist post so please excuse any lack of etiquette that I might not be familiar with.
I’m looking to create multiple entities (‘regular sensors’) from a single value.
Long story short, we have a system to calculate the price of power based on type of day and hour in the day.
- 3 types of day (bleu, blanc rouge) → Guess the country
- 2 types of hours for each (low-cost, high cost)
=> For a total of 6 kWhr prices
The idea is to create 4 entities giving me the following values abse on the “power” of an équipement.
- Price (in €) for a day “bleu”
- Price (in €) for a day “blanc”
- Price (in €) for a day “rouge”
- Price (in €) for a whole year (300 days “blanc” + 43 days “bleu” + 22 days “red”
This is my current template test in dev tools (woring great !!! ) 
But if I want all thoses values, I need to create 4 sensors.
Is there a way to avoid having to retype all those variables dfinitions and définitions for each sensor ?
{## Initate available variables: ##}
{% set pwr = states('input_number.tempo_calc')| int %}
{% set bleu_HC = 10.56 %}
{% set bleu_HP = 13.69 %}
{% set blan_HC = 12.46 %}
{% set blan_HP = 16.54 %}
{% set roug_HC = 13.28 %}
{% set roug_HP = 73.24 %}
{% set heur_HC = 16.00 %}
{% set heur_HP = 8.00 %}
{% set nb_bleu = 300.0 %}
{% set nb_blan = 43.0 %}
{% set nb_roug = 22.0 %}
{## Calcul du cout / jour pour chaque type de jour ##}
{% set cout_jour_bleu = pwr * (bleu_HC * heur_HC + bleu_HP + heur_HP) /100000 %}
{% set cout_jour_blan = pwr * (blan_HC * heur_HC + blan_HP + heur_HP) /100000 %}
{% set cout_jour_roug = pwr * (roug_HC * heur_HC + roug_HP + heur_HP) /100000 %}
{## Calcul du cout annuel ##}
{% set cout_annee = cout_jour_bleu * nb_bleu + cout_jour_blan * nb_blan + cout_jour_roug * nb_roug %}
Puissance : {{ pwr }} W.
Jour bleu : {{ cout_jour_bleu | round(2) }} €
Jour blanc : {{ cout_jour_blan | round(2) }} €
Jour rouge : {{ cout_jour_roug | round(2) }} €
COUT ANNUEL : {{ cout_annee | round(2) }} €
HI, I am aware of the system (also in France but not using this). Have you already tried posting in the french HACF forum as they may have a solution already ?
Hello,
No, I’m used to deal with english stuff rather than the sometimes limited ressources in french.
I’ll try to have a look.
Have a good day
It is not that bad but yes…logically (?) a lot less people on the french forum and 2(!) discord channels. Just suggesting as one them may already have a solution that fits.
Thanks, This is exactly that I was looking for !!!
I just finished my design. I’ll pos it here if it helps others, but mostly for me to find it back later :- 
Estimate the cost /day and /year for a tempo appliance based on it’s power

## tempo_cost.yaml (loaded in configuration.yaml as a template integration)

{% if type == 'bleu' %}
{{ cout_jour_bleu }}
{% elif type == 'blanc' %}
{{ cout_jour_blan }}
{% elif type == 'rouge' %}
{{ cout_jour_roug }}
{% elif type == 'annee' %}
{{ cout_annee }}
{% else %}
{{ -1 }}
{% endif %}
{% endmacro %}
In my example, I used an input_number HELPER named tempo.calc to intiate the calculations. It stores the value in watts and is changed in the dashboard with a slider.
Because the cost is linear, I prefered to have more control from 0 to 100 and multiply the result by powers of ten.
For example : 1500 W is 100 * 15 so I get the cost or 15 watts and multiply by 100
NOTE
For reference, here is the yaml code for the vertical stack of the dashboard.
It needs mushroom_cards and card_mod installed

*Note :*
-
Le cout de l'éléctricité est linéaire.
***200W** coûte **10x** plus cher que **20W***
Pour **2500W** par exemple, choisir **25W** puis faire **x100**
Please ask if you have any questions.
