Describe the issue

I have setup a couple of covers at home but they act weird. Let's take one example of a store Control Method: summer Cover Position: 4% End Sun: In 5 hours Manual Override: Not running Start Sun: 5 hours ago Sun Infront : Detected

Climate mode activated, presence mode not activated and external temperature activated. The temperature of the internal sensor is 24C and the minimal temperature is 19 and maximal temperature is 21C The external temperature is 24.5C The weather is sunny.

Hence I don't understand why the cover remains open at 4%, for me it should be fully closed.

Reproduction steps

Setup an automatic cover with an external temperature sensor, internal temperature sensor, weather. Wait for the cover to be exposed to the sun, weather sunny, high temperature inside and outside (above the max range of the confort temperature) Expectation: Cover should be closed Actual: Cover is opened at 4%

Diagnostics dump

No response

Can it be that the minimal delta position is preventing it to go from 4 to 0 zero?

[bend]

Everything is set to the minimum

[basbruss]

presence mode not activated

With this do you mean that you have not set up a presence sensor or that the state of that sensor indicates a deactivated mode?

[bend]

@basbruss Indeed no presence sensor, and the minumum delta to move the store is set to 1% and 2 minutes

[basbruss]

Ah okay, that is the origin of the misleading position. When there is no presence sensor set it assumes there is always presence. Therefore we should first focus on blocking direct light rays while allowing natural light to come in. So even in summer mode the cover will return to the calculated optimal position that holds both conditions. If there is no presence we don't care about natural light coming into a room, so than the cover can close fully within summer mode.

[bend]

my covers are solar covers, so they let the light in by retaining UVs and heat. so it should be closed even is someone is at home to avoid the house to heat too much. What should I do to configure that ?

[bend]

If I set a presence detector, it means covers will only close if I'm not home ?

[basbruss]

Or add a dummy input_boolean that always returns off. I can add a strategy option for see-through covers that block UV and heat to close fully in summer mode with presence. Do you mind if I change this issue to a Feature request for that?

[bend]

@basbruss yes go ahead. I will do that in the meantime :) Thanks for your help

@basbruss do you have any documentation on how the Control method is calculated ? (Summer, Intermediate, Winter) Thanks

[bend]

I've set the presence with a binary sensor like indicated I have the following now: Covers stays opened, but sun is detected

So basically when the reference temperature is above the maximum comfort temperature.

Yes, that is right since the control method is indicating intermediate or in other words the measured temperature is within the minimal and maximum comfort temperature range. Resulting in normal adaptive behaviour.

[basbruss]

The control method is based on the strategy used in this paper https://www.mdpi.com/1996-1073/13/7/1731

@basbruss outside temperature and inside temperature are both higher than max temp set, the weather temp however is at 19. So I guess there is a prioroty on the weather temperature ?

I've changed the max and min value to very low values and now it is in summer mode however covers stays at 0% (even though I've waited enough time to be sure that automation gets triggered).

[basbruss]

That is true, now I look at it, it could be better to prioritize the outside temperature sensor over the weather attribute.

Yes, 0% means fully closed and is therefore the wanted state in summer mode.

Do you have a discord so we can discuss that ? Something not clear for me.
