Push button Dimmer

[Patou]

Hello
I want to use an espeasy board to replace existing push button dimmer and be able to control also the lights from remote by Domoticz
I understood good how to do it from Domoticz (write to a GPIO defined as "PWM"), but I want to have the dimmer also working from one push button locally.
This means :
Short push on button (0.25sec) : On at the latest programmed level, second short push on button : Off
Long push on button : Light up from existing level to max level in 1 ... 2 sec seconds, long push on button : light down from existing level to zero When switch is released stay at the level.
In basic like language i can create a loop and increment/decrement a variable ... and send this variable to a GPIO defined as a pwm output but we cannot created loops in rules !!
I saw on the "Devices" the possibility to configure a switch input as a dimmer with a dim level but found no explanation about this in the forum or tutorials
Can somebody help in starting this project ?

Hello
I have posted this in may last year and get no answer
Probably what i want to do is not so easy with rules based on events
But maybe somebody reads this again and knows how to do

Hello all,
This rules works but the timerset on 1 sec is too slow is there a plan to have an instruction timerset in msec or even in 100 msec ?
Or is there an other way to introduce a delay in the rules ?

On BP-Up#State=1 do
if [BP-Up#State]=1
event,up
timerset,1,1
endif
endon

On Rules#timer=1 do
if [BP-Up#State]=1
let,2,[var#2]+100
timerset,1,1
endif
endon

Thanks in advance for a reaction

You could use double click or long push for the button.

Hello
Thanks for your reaction
But I do not see how long pulse or double click will increment a variable from 0 to 4000 in let's say 100 increments ( 0,100,200,300, ... 4000) in a controlable time of about 2 to 10 sec
Please explain
Patou

The double click will trigger faster than once a second I think.

Hello
I found a solution with an external NE 555 to clock a frequency of about 2... 4 Hz.
When Bp is pushed at every clock puls a variable is incremented and the result is used in a pwm command.
If the internal pwm is used range : 0-1024 and step 32 gives about 10 sec from min to max with a reasonnable resolution ( total 30 steps)
For the external multiplexer the steps are of 128 because the max is 4096 (12bit)
The unit works on the internal pwm I am waiting for the multiplexer to text

implemented smooth inclusion

Hello,
Using the newly implemented lop timer msec, an external oscillator is not any more necessairy as you have programmed in your rules.
It is now also possible to do indirect adressing and the number of variables is not any more limited to 16.
So I have created a table with 20 values from variable 1 to 20 with values following a logarythmic trend.
%v1=20 %v2%=30 %v3%=44 %v4%=63 %v5%=87 %v6%=116% v7%=150 %v8%=188 %v9%=231 %v10%=279 %v11%=333 %v12%=390 %v13%=452 %v14%=519 %v15%=591 %v16%=668 %v17%=750 %v18%=836 %v19%= 927 %v20%=1023.
Logarithmic trend is better than linear for dimmer( more smooth).
This program line make indirect adressing for the pwm value :

Code: Select all

 pwm,4,[var#%v21%]

The complete rule for 1 dimmer is as follow. (One Esp can handle 2 dimmers limitation is the precision of the loop timer msec!)
(You have to add the lines for the second dimmer usinf BP2 and all the second variables of the dummy devices)

Sorry I put 2 times the same picture of the devices !!

It is smoother and easier to implement for me.
I have no limit on the number of pins to manage
I am using PCA9685 to control LED room illumination
And I set the smoothness with the help of time and the divider coefficient

[Patou]

Hello Vitalik,
Can you share your rules and the settings of the PCA9685 ?
I do not understand what you mean with : "And I set the smoothness with the help of time and the divider coefficient"
Using the dim duration on an pwm command of a gpio from the Esp 8266 stops the execution of the rules for the dim duration. This is not very convinient !
Thanks in advance
Patou
