IF statement on %eventvalue%

Hi,
V2.0
I set up a rule as follows.
on configFlowSensor do
if [%eventvalue%] = 1
// Do something like set a GPIO output
endif
endon
I send the following HTTP request.
http://<your esp ip>/control?cmd=event,configFlowSenor=1
With the IF statement i get no response, without the IF statement it will set the digital output. The IF statement seems to ignore the value in %eventvalue% although it does trigger the rule.
Any pointers?
TIA
Ray

As seen in the wiki here:
https://www.letscontrolit.com/wiki/inde ... _Reference you cannot pass values with the event command.
To do so I suggest you try the TaskValueSet together with a dummy device (if you insist on using HTTP). If you use MQTT you could resolve the matter by using the MQTT import or use the TaskValueSet via cmd.

What about the rule
on configFlowSensor do
if [configFlowSensor#ValueOfDevice] = 1
// Do something like set a GPIO output
endif
endon

It is possible with TaskValueSet
You sent event value and write it into a dummy using taskvalueset within the event. Then you can check the dummys value within rules.

You still start by sending http command with event value:
http://<your esp ip>/control?cmd=event,configFlowSenor=1
On the receiving ESP you create a Dummy device, lets say as device 1 in the device Tab. You name the value , for example memory
Code: Select all
On configFlowSensor do
TaskValueSet 1,%eventvalue%
if [Dummy#memory]=1
// Do something
endif
endon
That should work!

Not working. Messed the rules! BTW: TaskValueSet need 3 parameter...

You are right about the TaskValueSet needing 3 parameters. But then there is no reason y th shouldn't work

I've tested it and does not work for me. I mean, you can not transmit values to an event. The parser seems to ignore more than 1 value after "event". It is only interested in the event name....
The messed rules seem to be an issue of core 2.4.0....

I just tested this on one of my nodes running R142
it definitly works the way I described

You can send values, check the wiki

Ok, now I got it. The "=" after event name was wrong (I had ",")...

Code: Select all
on testevent do
TaskValueSet 5,4,%eventvalue%
endon
Code: Select all
http://x.x.x.x/control?cmd=event,testevent=3
This works on 2.0.0.x

I have now moved this section to its correct section
https://www.letscontrolit.com/wiki/inde ... alue.25.29
I hope more people will use this awesome technique (I sure hadn't seen it before you pointed it out).

I use this rule set to pass GPIO # as event argument.
Code: Select all
on sniff#a do
event event1=%eventvalue%
endon
on event1 do
pcfpulse %eventvalue%,0,200
endon

Clever, will try to add this to the wiki as well.
