Simple flow to increase brightness

[Wroet]

I have a Homey-pro and just getting started.
But as I proceed, I start feeling dumb and frustrated as I can’t get something simple to work.

I have several Zigbee lights (Ikea Tradfri and Hue) and a few remotes (Tradfri 5-button and 2-button).

What I want seems very simple, but I am not able to figure out how to do it (without adding 20+ flows).

When I press the “increase brightness” button, Increase the brightness level with a 10 %.
So when it is at 20%, set it to 30%, etc. up to 100%
Similar when I press the “Decrease brightness” button, down to 10%.

Ideally this should be done gradually (in 1 or 2 sec), but that’s optional.

If I remove the bulbs and remote from Homey and pair them directly, it works perfectly.

WHEN
‘Increase dimlevel button’ pressed.
THEN
Calculate variable ‘dimlevel’ = ‘dimlevel’ + 0.10

WHEN
‘Decrease dimlevel button’ pressed.
THEN
Calculate variable ‘dimlevel’ = ‘dimlevel’ - 0.10

WHEN
variable ‘dimlevel’ is changed
THEN
Dim light to ‘dimlevel’ (during 5 seconds)

Thanks a lot!
Seems that I’d been using the wrong ‘dim lights’ option in THEN. (relative dim)

[Wroet]

Not exactly what I was looking for, but very helpfull nonetheless.
Thanks

Maybe this one suits your needs: < groep > App voor Homey | Homey

Hi Wim,

I have tried your logic, but it does not seems to work. My variable is empty after executing it. It shows the number 43, but thats a default number.

Any idea what is going wrong?

Thanks.

[Wim_Post]

use double {{ before and }} after calculation.

dimlevel = {{dimlevel + 0.1}}

Hi @Wim_Post
Please keep it in English. Thanks

[Mexxwelll]

That’s working now! Bedankt !!

Any idea why this logic is working and not without the {}??

[Peter_Kawa]

Just because the rtfm says so

Right, did not see that small text beneath. Thanks.

Contrast is a bit low and I was put off guard by the name of the logic card “Calculate (numeric variable) to text.”

Thanks so much for this thread as it’s exactly what I am trying to do.

However, I am stuck with the very first part. I can create and set a variable for the Dim level, but how can I read the existing value of the dim level variable from a lightbulb. I can see the value, and adjust it, but I cannot read it with logic function.

@AWBoonen

Calculate (numeric variable) to text

Seems to be a (translation) error @ Pro 2023.
The ‘text’ example text should read ‘number’.
I’d nudge support about this, to get it fixed.

[Peter_Kawa]

Is this more clear, Mark?

@Wim_Post

WHEN
‘Increase dimlevel button’ pressed.
THEN
Calculate variable ‘my_dimlevel_var’ = {{‘my_dimlevel_var’ + 0.1}}

WHEN
‘Decrease dimlevel button’ pressed.
THEN
Calculate variable ‘my_dimlevel_var’ = {{‘my_dimlevel_var’ - 0.1}}

WHEN
variable ‘my_dimlevel_var’ is changed
THEN
Dim light to ‘my_dimlevel_var’ (during 5 seconds)

[Rmb]

Maybe the formula is seen as a text string?

Thanks for the quick reply Peter, unfortunately that didn’t help. Probably I’m not understanding the logic…

My smartbulb displays a variable named “Dim level” that states the level that the lightbulb is dimmed to.

When I follow this example and I create my own variable called “dim_level_var” I have to set an initial value, I cannot set it to equal the variable named “Dim level” attached to the bulb. This is what I believe I need to be able to do.

Therefore whenever I initiate the flow in this screenshot the calculation takes “dim_level_var” then adds 0.1. This means that the flow always outputs “dim_level_var” = 0.2. The var “dim_level_var” = 0.1 and then the flow adds 0.1. When I start the flow again it simply does the same thing.

[Peter_Kawa]

YW, Mark
The lights should be driven by a separate flow, like
WHEN
variable ‘my_dimlevel_var’ is changed
THEN
Dim light to ‘my_dimlevel_var’ (during 5 seconds)

So deattach them from that flow, and start a new flow (on the same canvas), starting with this logic card

To get this result:
