Use Rotary Encoder no counter just up or down

For one of my amps U build an IR transmitter so I can use it form a distance (it's on a cabinet out of reach) with my Logitech remote.
No I like to add a volume control button to my remote so I am able to control it also without remote.
For that I want to use a Rotary Encoder. I have the encoder working, but now I want to be able to know when I turn it clockwise (+1) or counter clockwise (-1) and I do not need the counter for more.
So i like to set it after every turn click to 0 and use a rule to figure out which side is was turned and use that as a command to fire the IR signal.
Is this possible with the standard stack?

Have you tried the 'Switch - Rotary encoder' plugin?
I'd expect the counter to go down when turned in the 'opposite' direction, (though I've never used this plugin).
You can detect and handle that in rules.

I indeed use the rotary encoder plugin it counts down or up. But how do I use that in a rule?
And when I come back later and do the same action it still nows that it goes down or up?
In short, I am only interested in the direction of turning, the counting is not needed for this project

You can add a Dummy Device to your Devices list, give it a useful name, say Variables and enable it.
Then add this to your rules:
Code: Select all
on System#Boot do
TaskValueSet,12,1,[Rotary#Count] // Assume the Dummy device is on task 12
endon
on Rotary#Count do
if %eventvalue% > [Variables#Dummy]
// transmit IR volume up command
endif
if %eventvalue% < [Variables#Dummy]
// transmit IR volume down command
endif
TaskValueSet,12,1,%eventvalue% // Store current value
endon
Edit: Changed to not turn down the volume when nothing changes but a periodic event is fired (and the Count value doesn't change).

Hi, this is a long shot as this post was last active in 2021 but..
The code you've posted isn't working for me.
Whenever I turn the encoder I only get this and no IR commands are sent.
Code: Select all
250812 : Info : QEI : 31
250816 : Info : EVENT: VOL#Counter=31
251612 : Info : QEI : 30
251616 : Info : EVENT: VOL#Counter=30
251912 : Info : QEI : 29
251915 : Info : EVENT: VOL#Counter=29
my rules are:
Code: Select all
on System#Boot do
TaskValueSet,12,1,[VOL#Count] // Assume the Dummy device is on task 12
endon
on Rotary#Count do
if %eventvalue% > [Variables#Dummy]
IRSEND,NEC,0x616E2AD5,32
endif
if %eventvalue% < [Variables#Dummy]
IRSEND,NEC,0x616ECA35,32
endif
TaskValueSet,12,1,%eventvalue% // Store current value
endon
on Switch#State do
if [Switch#State]=1
IRSEND,NEC,0x616E02FD,32
else
IRSEND,NEC,0x616E827D,32
endif
endon

Just to be sure, what build are you using?
Also do you have a task configured with the IR-TX plugin?

Look at your code... it seem that your rotary encoder task is called VOL and the taskvalue is called Count ([VOL#Count])
So this line:
you should change into:
