Yes, saw those, and just copied and pasted the whole code and tried again, but still nothing.
The quick simple one works though, every time.
Strange.
Really strange 
Is there any error log in openhab.log about the not working rule? You can force logging some values
set this line
logInfo ("fadeout","percent = {}",percent)
right below Light_GF_Living_Planets_1.sendCommand (percent) to see if percent is decremented.
Ah. I just saw a flaw… If the Light is ON, maybe the state isn’t an instance of DecimalType.
[...]
then
if (Light_IN_Frontroom_Birds.state !instanceof DecimalType && Light_IN_Frontroom_Birds.state != OFF)
Light_IN_Frontroom_Birds.sendCommand(95)
percent = ((Light_IN_Frontroom_Birds.state as DecimalType)/5).intValue * 5 //round to 5
fade_Timer = createTimer(now.plusMillis(500)) [|
Light_IN_Frontroom_Birds.sendCommand(percent)
if (percent > 0) {
percent = percent - 5
fade_Timer.reschedule(now.plusMillis(500))
}
]
end
Just the interesting part…
Also beware the typo. Shouldn’t that be fade_Timer.reschedule(now.plusMillis(500)) ?
yes, did not see this in first place
Hey Udo,
Can you help me for the below topic?
I want to setup a Dimmer item, with which I waant to bind the http binding, I can use the rule present in the demo.rules file, but not sure how to send the percentage value of it to my http server running on Raspberry pi3. Any Ideas will be appriciated.
Well, given a dimmer item bound to http, this should be very easy…
Dimmer myDimmer "My http Dimmer is [%d %%]" {http=">[*:POST:http://www.domain.org/home/lights/23871/?status=%2$s&type=text] <[http://www.domain.org/weather/openhabcity/daily:60000:REGEX(.*?<title>(.*?)</title>.*)]"}
(Item definition from documentation)
Now to change the value, either use a slider in Basic UI or something similar, with “real” sliders, or use INCREASE/DECREASE commands and a rule to set the value:
rule "My http dimmer"
when
Item myDimmer received command
then
if (receivedCommand == DECREASE) {
myDimmer.sendCommand((myDimmer.state as DecimalType) - 5)
}
else if (receivedCommand == INCREASE) {
myDimmer.sendCommand((myDimmer.state as DecimalType) + 5)
}
end

Udo,
Thanks for your reply,
My setup is as below,
Dimmer Led_R “Red” (FF_Nishit, Lights){http=">[*:GET:http://192.168.0.108:5000/red3/%2$s]"}
and rules,
rule "RED LED"
when
Item Led_R received command
then
var Number b = 0
if(Led_R.state instanceof DecimalType) b = Led_R.state as DecimalType
if(receivedCommand==INCREASE) b = b + 10
if(receivedCommand==DECREASE) b = b - 10
if(b<0) b = 0
if(b>100) b = 100
sendCommand(Led_R, b)
end
can you point any mistake, currently it is not working
Hey Udo,
I tried your hings and I got the success bu I get never ending loops, can you suggest how to stop them?
I have no idea, why you get a loop. you can try to use
when
Item myDimmer received command DECREASE or
Item myDimmer received command INCREASE
then
as the trigger part, but my rule took care of this, because there would have been only a sendCommand if the received Command was INCREASE or DECREASE, this should suffice (in fact my rule will trigger itself, but the received command will be of Type Number, but not INCREASE/DECREASE, so when triggered from itself, it should do nothing at all).
On the contrary, your rule from posting #14 would possibly loop forever, as it will send a command, even if it did not receive INCREASE/DECREASE, but also ON/OFF or 0 to 100.
Thank you very much Udo, don’t know what I did wrong, but it is working with your rule.I changed nothing in it just wrote the whole code allover again and it is working now.
Udo,
when I do the following,
Dimmer Led_R "Red" (FF_Nishit, Lights){http=">[*:GET:http://192.168.0.108:5000/red3/?status=2$s&type=text]"}
it send the the whole link including’?status=2$s&type=text’ instead of the value of b
I want to send it as following,
192.168.0.108:5000/red3/50, instead of 50 there should be the value of variable created in the rule.
If you look at Udo’s example, it has a % symbol right about where you want to substitute the value.
You just have to take care with these things.
I also have included ‘%’ but it is not working.Here are my codes.
Item.
Dimmer Led_R "Red" (FF_Nishit, Lights){http=">[*:GET:http://192.168.0.108:5000/red3/?status=%2$s&type=text]"}
and the rules,
rule "dimmer Led-R"
when
Item Led_R received command
then
if (receivedCommand == DECREASE) {
Led_R.sendCommand((Led_R.state as PercentType) - 5)
}
else if (receivedCommand == INCREASE) {
Led_R.sendCommand((Led_R.state as PercentType) + 5)
}
end
I want to send the following link via http binding to my server,
192.168.0.108:5000/red3/(the value from dimmer )
can you suggest any changes?
Oh, come on. “not working” is so unhelpful. What, if anything, does it send now? How are you sending INCREASE/DECREASE commands? Does the rule trigger?
I send the Increase, decrease command through Slider -dimmer item which I posted above.
It does not send the value of ‘b’, but it sends the whole link “192.168.0.108:5000/red3/?status=%2$s&type=text” I have also posted my rules and Item settings in the previous comment.
Maybe you have to set the label of the item, so please try
Dimmer Led_R "Red [%d %%]" (FF_Nishit, Lights){http=">[*:GET:http://192.168.0.108:5000/red3/%2$s]"}
(removed spaces for better readability)
Udo,
When I move the slider from the Ios app, my python scripts replies ’ Could not convert string to float’
Kindly note that I need to use float value from the dimmer,
I also tried int, but when I move the slider, my python script replies 'invalid literal for int90 base 10 : 2$s’
also tried using 2$d, but getting the same error,
So how to send the int or float value directly?
Udo,
Can you help me with making a Main voltage dimmer
i has got the module done but iam not so good in programming,

Sorry I don’t use mqtt yet, so I could only guess. But of course you will have to use a mqtt broker (e.g. mosquitto) for communication, the mqtt binding and the correct settings. There is lot of stuff about mqtt in this forum…
Oké no problem,
The mqtt setup is done ect
