If anyone is interested, it’s possible to reduce this:

      position: >
        {% if state_attr('sun.sun', 'azimuth') | float < 80 %}
          0 
        {% elif state_attr('sun.sun', 'azimuth') | float >= 80 and
        state_attr('sun.sun', 'azimuth') | float < 170 %}
         100
        {% elif state_attr('sun.sun', 'azimuth') | float >= 170 and
        state_attr('sun.sun', 'azimuth') | float < 220 %}
          {{ (((-2 * (state_attr('sun.sun', 'azimuth') | float )  + 440) / 10) | int) * 10 }}
        {% elif state_attr('sun.sun', 'azimuth') | float >= 220 and
        state_attr('sun.sun', 'azimuth') | float <= 250 %}
          0
        {% elif state_attr('sun.sun', 'azimuth') | float > 250 and
        state_attr('sun.sun', 'azimuth') | float <= 300 %}
          {{ ((( 2 * (state_attr('sun.sun', 'azimuth') | float )  - 500) / 10) | int) * 10 }}
        {% else %}
          100
        {% endif %}

to this:

      position: >
        {% set a = state_attr('sun.sun', 'azimuth') | float(0) %}
        {% set values = { 80: 0,
                          170: 100, 
                          220: (((-2*a+440)/10)|int(0))*10,
                          251: 0,
                          301: (((2*a-500)/10)|int(0))*10 } %}
        {{ values.get(values.keys() | select('>', a) | first, 100) }}

EDIT

Correction. Added missing closing brace to final template.

It’s right if you want it to behave differently from the original version (because your version produces different results).

Copy-paste this into the Template Editor and experiment with it:

{% set a = 230 %} {{ a }}

The original version:
{% if a < 80 -%} 0 
{% elif a >= 80 and a < 170 -%} 100
{% elif a >= 170 and a < 220 -%} {{ (((-2*a+440)/10)|int)*10 }}
{% elif a >= 220 and a <= 250 -%} 0
{% elif a > 250 and a <= 300 -%} {{ (((2*a-500)/10)|int)*10 }}
{% else -%} 100
{% endif %}

Revised version:
{%- set values = { 80: 0,
                  170: 100, 
                  220: (((-2*a+440)/10)|int(0))*10,
                  251: 0,
                  301: (((2*a-500)/10)|int(0))*10 } %}
{{ values.get(values.keys() | select('>', a) | first, 100) }}

Your version:
{%- set values = { 0: 0,
                  79: 100,
                  170: (((-2*a+440)/10)|int(0))*10, 
                  220: 0,
                  250: (((2*a-500)/10)|int(0))*10,
                  301: 100 } %} 
{{ values.get(values.keys() | select('>', a) | first, 100) }}

You seam to know your coding stuff :slight_smile: I was wrong, deleted my post.

Would you help including some more variables into the code?

65

What do you want it to do?

66

Currently the shading is done by azimuth, on fixed values from the guy who started this.

But actually shading should be done by a lot more variable, especially calculating the position of the roller shutter. I work on the calculations and variables right now, but I am by no means able to transfer the calculation into code.

67

Its more like,

  • you know the direction the window is facing, so you know from when to when azimuth shading is required (like -30+50°)
  • you know the height of the window, the depth of the wall with window sill (and acceptable sun strake behind the window sill, and you could calculate from what elevation no shading is required anymore since the wall would shade it itself.
  • you know from what current elevation the user wants shading so when to start the daily shading work
  • and from what max day elevation shading is generally required, so it wont run in winter and spring
  • you may want to consider a cat door as a minimum opening, no matter what the shading calculation gives as shading position.
  • you know the % value when window is fully shaded by the shutter
  • you know the % value when the roller shutter starts covering the window

With all that the calculation of the shading position of the roller shutter is just math.

and from that, one could code a code that just needs the values of the window to run shading all by its self with out big fiddeling. and does the shading in a way the acceptable sun streake inside is never exceeded, but the shutter is maximal open at the same time. who wants to live behind shutters is the idea here.

Those calculations (algebra) and the flow chart i could do, but i cant do the coding.

68

and beyond that, one may wants to prefer a awning thats mounted over the window if its not raining or windy or the awning wont cover enough of the window.

or has a roof window at an angle

or has shading by other objects and only requires shading in other azimuth degres.

and my want that it closes/open on dusk and dawn, probably on two steps, like pre open, open and pre close and close, depending on lux

and as well, one may want to asses the cloud level and the forecast temp and indoor temp or if an AC is running etc. pp

it would get quite complicated.

Here are all the variables I think would be likely needed.

User input mainly, but also some sensor values.

First we need these global variables:

  • forecast out door temperature for the day
  • global indoor temp limit with no AC
  • global indoor temp limit with AC of room
  • global indoor temp limit with global AC status
  • global flat/house indoor temp for if no room temp entity available
  • cloud level status in %
  • cloud level to activate shading
  • sun elevation
  • sun azimut
  • wind speed sensor
  • rain event sensor
  • LUX sensor
  • global switch shading: on / off for for time x / off permanent
  • global switch nightly shutters: on / off for time x / off permanent

now we need window facts for each window.

  • window number
    • friendly name
    • roller shutter entity
    • window related switch shading: on / off for for time x / off permanent
    • window related switch nightly shutters: on / off for time x / off permanent
    • room temp entity (if not available, use globale indoor temp)
    • sensor for room AC-Status (if not available use global if not available assume AC off)
    • room temp limit without AC
    • A/C status (always shade when on “cooling”)
    • direction the window is facing in decimal ° compass direction
    • deviation from vertical if e.g. roof window
    • height of window in mm
    • width of wall including inside window sill in mm
    • acceptable width of sun streaks (AWS) in mm
    • depth of the shutter from outside wall
    • azimut deviation from window direction to start shading (would be mostly negative)
    • azimut deviation from window direction to stop shading (would be mostly positive)
    • minimum elevation that is required for shading (max elevation will be calculated for each window by wall thickness (width of window) and AWS) out side of those two limits shutter will be at 100%
    • start shading in % of roller shutter
    • fully shaded in % of roller shutter
    • max shading position (e.g. to prevent lock out from terrace doors or animals from their doors)
    • two step opening in morning? (y/n)
      • offset for non working days (y/n)
      • offset time
      • step one opening on lux > xx
      • step one opening lux duration
      • step one opening fallback elevation
      • step one opening in %
      • step two opening on lux > xx
      • step two opening lux duration
      • step two opening fallback elevation
      • step two opening in % (100% usually)
    • two step closing in evening y/n
      • step one closing on lux < xx
      • step one closing lux duration
      • step one closing fallback elevation
      • step one closing in %
      • step one closing ignore max shading position to prevent lockout of animals y/n
        • time offset after step one to close to 0%
      • step one closing ignore
      • step two closing on lux < xx
      • step two closing lux duration
      • step two closing fallback elevation
      • step two closing in % (0% usually)
      • step two closing ignore max shading position to prevent lockout of animals y/n
        • time offset after step two to close to 0%
    • awning over window (y/n)
      • prefer awning over shutter for shading (y/n)
      • fall back to shutter on wind speeds over
      • fall back to shutter on rain (y/n)
      • entity of awning
      • start shading with awing %
      • 100% of awning shades 100% (including AWS) on sun elevation °
      • fall back if awning cant shade 100% (y/n)
      • % when to fall back if awning cant shade 100%

First we need some code that puts that all into perspective.

Then we need an automation, that runs every time the azimuth changes 1 full degree and considers all these values to come to a conclusion for the roller shutter or awing of each window and sets their cover.set_cover_position and then move on to the next one. Rinse and repeat.

The algebra part is pretty straight forward:

Wall thickness + indoor window sill + acceptable sun stake - position of roller shutter in the wall = one part of the triangle (a)

The other one (b) we get with

tan(alpha) * a = b

where alpha is the elevation

b is the position inside the full window height for the roller shutter to archive good shading by the owners specification.

so we could easily calculate a percentage from that.

100 / windows height * b = % to be closed (x)

Now we need to calculate the roller shutter position, we got a no shading value (c), probably 98%, and a full shading value (d), probably at about 15% so we have

c - d = e (100% distance from no to full shading)

e * x + c = roller shutter position in %

Now we need to calculate from what elevation on the roller shutter could be fully open. but this could also be entered by the user, since there could be a balcony or a roof eaves that shades the window in a different way than just the wall and its thickness.

What do you say @123 doable?

of course we need a variable block for global and each window and some automation that would consider the rest of the global variables like the temps and clouds and so on.

I think I got the algebra for the opening position inside this string

edit says: forget about this, the formula is all wrong, im working on it in the thread linkt with the 4 in 1 automation to posts further down. The solution will be there when I am finished with the roller shutter stuff.


set a = #deviation from vertical if e.g. roof window
set b = #height of window in mm
set c = #width of wall including inside window sill in mm
set d = #acceptable width of sun streaks (AWS) in mm
set e = #depth of the shutter from outside wall
set f = #start shading in % of roller shutter
set g = #fully shaded in % of roller shutter

set shutter_shading_pos = ((tan('sun.azimuth' + a) * 0,01 * (c + d) * b * (f - g)) + g)

I say you should start a new topic because this one was solved a long time ago and your requirements are substantially different. By starting a new topic, it’s more likely to attract fresh eyes to it.

70

yes, sir

71

Not to mention that it was a decent amount of work to get the original automations to work with just the azimuth vs shutter positions for 4 groups of shades.

by my count you’ve added about 60 different variables into the mix. I doubt anyone is going to want to tackle that.

If you get all the math worked out then I’m sure someone can convert it into a working template.

Good luck.

72

I have my elevation2shutter pos calculation in combination with parts of your azimuth code running on one test device (I have a baby diaper changing table that moves up and down to be stored away thats working with a roller shutter motor and is therefore able to resemble a roller shutter) right now, iits all totally messed up, but I’ll get it to work. Probably just did some silly stuff integrating all the calculations into one formula. I just start with an elevation follow today, and then build from there.

what really would help would be a code that simulates a days sun movement so I have sensors for azimuth and elevation to bind the code to that simulat 24h of elevation and azimuth inside 10 minutes. so I could see if my code does what i want it to do, but dont have to wait the whole day.

got some recommendation how to make that happen?

73

not automatically.

you could paste the template into the dev tools template editor and create variables for the elevation and azimuth and use those variables in the template instead of the real sun attributes.

then you can just manually change the variable values and see the result of the template change.

that’s what I did in coming up with the original templates above to test things.

Im struggling to get a for each loop working. I am not a coder…

for azimuth thats pretty simple in theory, but not for me cooding noop would like to have it change in half degree increments (0,5) every second, so a day would take 12 mins.

for elevation, this is much more complicated as is oscillates between -20 and +40 at azimuth 0 and 180 at my location. I dont need the compound curves the sun really does. linear function is totally acceptable.

I think it should work like: you enter the elevation level you want to test and the corresponding lower elevation level is set to upper elevation -80°

also the increment should be variable. to adjust for speed and detail.

Now one could just use simple math to get the corresponding elevation to the azimuth and simple set these from a table.

I may be able to utilise @123 shorted code from here

I just put that into excel to get the calculations right. I cant upload the excel file, so here is the formulas (csv export

set required increment		0,5
Set elevation max ange to 		67
zero azimuth elevation then is	(formula: =C3-80)
change per azimuth			(formula: =80/180*C2)

First row Azimuth is 0
second row Azimuth is {formula: =WENN(A9<360;A9+C$2;"") } #you my need to replace "wenn" with "if" and pull down to 1000 rows.

First row Elevation (same row as 0 Azimuth) {formula: =WENN(A9="";"";WENN(A9<=180;(A9*C$5/C$2)+C$4;((A9-(2*(A9-180)))*C$5/C$2)+C$4))} # you may need to replace "wenn" with "if" and pull down to 1000 rows.

Now you got the Table for Azimuth to elevation calculation thats almost the real sun movement for your location when you enter the desired highes elevation of the day you want to test for.

But how to get that into a code in here, I have honestly not a clue how to do that.

And here is the result for a summer day in my area

awesome, thanks a lot, it will help me with the code in my full solution that moves the shutters according to elevation during the shading.

thanks

Hi, came across this thread because I’d like to do the same thing.

I’m just looking at your code @Guesswho620 , and I believe is solely based on azimuth of the sun based on the season, and not if its actually sunny or cloudy outside? I could be mistaken on this.

I would like to setup something similar based on a few things:

  • only for sunset
  • based on azimuth
  • based on presence (being home)—I have set this up for another automation and use the state for that
  • based on my weather station sensor that has a lux sensor (already reporting to HA via an integration)

The last condition is for example, I don’t want the blinds adjusting if its not sunny AND it does not have to depend on that actual value except if its above a certain value (its sunny or not sunny). For example, on day like today in March with sunny skies, a lux under 95w/m2 is comfortable on the eyes but I’ll have to figure out how azimuth corresponds to lux on a clear during the late sping/summer/winter/fall seasons on , sunny day, and maybe even a cloudy day, but basically this automation would be running between the times of after 3pm to about 9 pm…but that would depend on the season also. Heres a sunny day example in march (2 days ago), and how it changes as the sun moves.

Perhaps this would allow me to intrduce a condition that if the lux is greater than X w/m2 for more than 30 seconds in the time of 4 to 9 pm, adjust the blinds/covers accordingly.

one thing to mention is with having the lux sensor, this eliminates the seasons coding part.

hi @finity

just wanted to follow up here on the code you provided:

data:
      position: >
        {% if state_attr('sun.sun', 'azimuth') | float < 80 %}
          20  
        {% elif state_attr('sun.sun', 'azimuth') | float >= 80 and
        state_attr('sun.sun', 'azimuth') | float < 170 %}
          90
        {% elif state_attr('sun.sun', 'azimuth') | float >= 170 and
        state_attr('sun.sun', 'azimuth') | float < 220 %}
          {{ (((-2 * (state_attr('sun.sun', 'azimuth') | float )  + 440) / 10) | int) * 10 }}
        {% elif state_attr('sun.sun', 'azimuth') | float >= 220 and
        state_attr('sun.sun', 'azimuth') | float <= 250 %}
          20
        {% elif state_attr('sun.sun', 'azimuth') | float > 250 and
        state_attr('sun.sun', 'azimuth') | float <= 300 %}
          {{ ((( 2 * (state_attr('sun.sun', 'azimuth') | float )  - 500) / 10) | int) * 10 }}
        {% else %}
          80
        {% endif %}

are the position values modifiable, like above? I tried to use my positions, but it doesn’t seem to like it on that parts where the azimuith falls on formula parts:

  {{ (((-2 * (state_attr('sun.sun', 'azimuth') | float )  + 440) / 10) | int) * 10 }}

 {{ (((-2 * (state_attr('sun.sun', 'azimuth') | float )  + 440) / 10) | int) * 10 }}

also, for me, I have a west facing window, thus if I change the azimuth settings i.e from 80, 170, 220, 251, 301 to something else, how would I have to modify the above formula parts?

also, does this overide the current position of the shade (whatever position its on) on every command?

thanks

What do you mean here?

what are you seeing to say “it doesn’t like it”?

it really depends on what the values are for the sun position vs the positions for the blinds.

without knowing the desired relationship between the two variables it’s hard to know what the formula values will be.

it doesn’t override the current actual position. It just commands the blind to move to a new actual position. Which will then be reflected in the position displayed after the move.

@finity thanks for replying, sorry I should more clear.

Here’s what would work for my situation. I only want the shade to block on the sun when its beaming through the west side window (not control it 24/7), basiclly, the position of the shade should change from 80% to 20% (when sun is approaching, 220 to 270) and 20% to 80% when the sun is going the other way (270 up to 320). Something like this below:

data:
      position: >
        {% if state_attr('sun.sun', 'azimuth') | float = 220 %}
          80  
        {% elif state_attr('sun.sun', 'azimuth') | float >= 220 and
        state_attr('sun.sun', 'azimuth') | float < 270 %}
          {{ (((-2 * (state_attr('sun.sun', 'azimuth') | float )  + 560) / 10) | int) * 10 }}
        {% elif state_attr('sun.sun', 'azimuth') | float >= 220 and
        state_attr('sun.sun', 'azimuth') | float = 270 %}
          20
        {% elif state_attr('sun.sun', 'azimuth') | float > 270 and
        state_attr('sun.sun', 'azimuth') | float <= 320 %}
          {{ ((( 2 * (state_attr('sun.sun', 'azimuth') | float )  - 520) / 10) | int) * 10 }}
        {% if state_attr('sun.sun', 'azimuth') | float = 320 %}
          80  
        {% endif %}

I haven’t tried this code, but I know its not going to work because if you place an azimuth of 319, it will return a position of 117% (when it should be close to 80%)

It really is high school math. I’ll need a graphic calculator to figure out the equation of the line within the azimuth and position ranges…lol

looks like this works for me

y= -1.20x + 344.00
