More Calculation options

[tf]

Hey Arie,

Would it be possible to add the following options in the Calculation for Boolean fields?

• False if any is true
• False if all is true

With these 2 inversions all possible outcomes are covered from the same setting.

Just asking …

As a follow-up on this issue and the related one in BLL, could the Boolean-calculation option in an AVD be extended with even more options to evaluate number of trues/falls before setting the aggregate Boolean to either true or false?

So could there be an option here that gives the user the option to choose 5 trues out of 8 Booleans for example.

I tackle this problem with regular flow-cards at the moment. With 4 different child-Booleans this is getting already quite elaborate. But how I have this setup at the moment, the complexity quickly explodes with each additional child-Boolean introduced.

Thanks again!

“So could there be an option here that gives the user the option to choose 5 trues out of 8 Booleans for example.”

This can already be done wif you use the Calculation: BLL.

Then you can check through a BLL/javascript if the $values array contains a certain amount of trues.

Thanks for responding Arie!

As an example, let’s say I would like this field to be true if at least 2 of the reflected variables are true. How should the code snippet look like than?

(I am not at all familiar with coding.)

I tried both searching the Homey-forum and Google, but do not know really where to start. 😬

Is this something I could/should use? And than check the result by a threshold.

As example, this will return an array of 3 items: all the trues.

let $values = [true, true, false, true, false];
return _.filter($values);

So, what you would need to enter in the calculation field is:

_.filter($values).length>=2

If you enter this into the BLL Calculation field, the field will evaluate to True/On when there are 2 or more reflected properties true.

Thanks again.

As a proof of concept this works perfectly as intended.

Now I will have to continue my ongoing pursue to stabilise my H23.

You’re the best!

False if are build in 2.15.2 (released later today in test.)

Thanks for having added this Arie.
