Feature Request: cover close winter mode

[tco99ttocs]

for the colder times, it would be nice, to close the cover in the night, but not within a given time or with the sun elevation. It should be work with a given temperature or weather forcasts!

For example: If the forcast temperature of the following night or the outside temperature is below a given temperature the cover should close. In this case also negativ values should work!

I don't know yet whether I want to implement a winter mode. But I still have a little time.

I would really like this function too. I have some roof window shutters on the north side and they tend to freeze when the temperature is above -5 degrees.

Thanks in advance.

Wouldn't it be easier to implement these wishes using the Force function?

[tco99ttocs]

normaly everything would be possible with the force function, but the question would be how complex will be the trigger for that!
there should be 3 components for the winter mode:

1. time based, open in the morning , close in the evening -> still implemented
2. sun elevation, opening when sun rises, closing when sun goes down, possible with the sun integration or with the sun elevation -> its implemented with the sun elevation
3. weather based, close if the weather forcast said it would be cold at night, so if the temperatur will be below a given one for example if the temperature will be below 6 degree in the night (using the hourly forcast) ! -> thats not implemented

Point 1 and 2 i used last winter, but if sun goes down at 5am als the covers will close at this time -> would be to early;)

To use the force function its neccessary to implement all 3 point, because force only has on/off!!

[tco99ttocs]

maybe it would be possible to use the shading part of the blueprint and change the temperatur from is above to is below!

[tco99ttocs]

{% set trise = as_timestamp(state_attr('sun.sun', 'next_rising')) | as_datetime | as_local %}
      {% set tsett = as_timestamp(state_attr('sun.sun', 'next_setting')) | as_datetime | as_local %}
      {% if (state_attr('sensor.Weather_Hourly_forecast', 'forecast')|selectattr('datetime', 'lt', trise.isoformat() )|selectattr('datetime', 'gt', tsett.isoformat() ))| map(attribute='temperature') | list %}
      {{ (state_attr('sensor.Weather_Hourly_forecast', 'forecast')|selectattr('datetime', 'lt', trise.isoformat() )|selectattr('datetime', 'gt', tsett.isoformat() ))| map(attribute='temperature') | list | min}}
      {% else %}
      {{ (state_attr('sensor.Weather_Hourly_forecast', 'forecast')|selectattr('datetime', 'lt', trise.isoformat() ))| map(attribute='temperature') | list | min}}
      {%endif%}

this code provides the min temperature of the following night (between sun setting and sun rising)! Maybe that will help to create that feature :)

I’m already very happy with this blueprint. I didn’t think that this would work so well and that the shutters would come down when the sun shines through a window. This means we can sit at the dining table and not be blinded by the sun. However, I would like to refine the whole thing a bit, but I don’t know whether this will work with the blueprint. In principle, the control is supposed to prevent two things. On the one hand, you don’t get blinded by the sun and on the other hand, the rooms don’t get too hot or the plants in front of the window burn. This means that in summer when the temperature is high, shading should always take place. In autumn and winter, shading should only take place when someone is in the house or sitting at the dining table, otherwise the sun’s rays can warm up the room to save on heating costs. I’m wondering how I could implement this.

You can use "Additional Condition(s) For Activating Sun Shading".

I would like to highlight another aspect of winter mode:
Most (if not all) shutters shall not be moved by force when they are frozen and stuck. So detecting this freezing by tracking temperature, humidity and rain/snow/fog/... And not moving the shutter at all until it was warmer than x for y period should be an option as well. Maybe even dynamically since heavy snow for two days takes longer to melt from rooftop windows then slight frost due to light rain for half an hour and temperature slightly below freezing right afterwards.

If I may add to @Xyolyp remark:
Yes, this is a feature element I miss. It would be good to set some "freezing temperatures" which could by as default from +1 to -5 °C as above the shade does not freeze and break when force-opened, and below -5 °C it is usually too cold and the shade (DE: Rolladen) does not freeze due to the fact that the ice sublimates. At least in my setting of the house.

Hi guys,

I love this implementation, in my case I also find missing a winter mode that would be great to have it, currently I do it externally control the blinds in winter, and I use the following logistics and I would like to contribute to the project.

• In the morning, depending on the level of outside light, I make a partial opening only so that light enters and the temperature does not exesive leave.

• in case the outside temperature is higher than X ºC I fully raise the blinds to take advantage of the outside temperature for heating.

• if the outside temperature is X ºC higher than the inside temperature and above the temperature of the next step, I fully raise the blinds to take advantage of the outside temperature for heating.

• in case the outside temperature is lower than X ºC I partially close the blinds to let only light in.

• This mode could be activated by an helper that determines whether it is summer or winter, as in the case of climate thermostats.
