HTTP request in rules

[remko2000]

I've an espeasy CO2 sensor and with this I want to send a window open. A can control my axa remote (= window opener) with this call from domoticz:

Code: Select all

http://10.0.1.102/open

So I thought I make a rule which send this command when my CO2 sensor reach a value of 2500 ppm. This is my rule:

Code: Select all

On CO2#PPM do
 if  [CO2#PPM]>2500
    SendToHTTP http://10.0.1.102/open
  endif
 endon

Problem is that this doesn't work. I read the wiki with tutorial rules but I don't find a proper example so this isn't help me. Someone any suggestions?

You have the syntax for SendToHTTP wrong,
it should be something like this:

Code: Select all

On CO2#PPM do
 if  [CO2#PPM]>2500
    SendToHTTP,10.0.1.102,80,/open
  endif
 endon

- No protocol prefix (ESPEasy only supports http, and that is implied by the command)
- Separate arguments for ip/hostname, port and file/location

The command syntax can be found here: https://espeasy.readthedocs.io/en/lates ... mmand.html

Indeed:

Code: Select all

On CO2#PPM do
 if  [CO2#PPM]>900
    SendToHTTP,10.0.1.125,80,/open
else
    SendToHTTP,10.0.1.125,80,/close
  endif
 endon

does the job.

The thing I don't like is the fact that my esp with CO2sensor constantly send 10.0.1.120,80,/open of 10.0.1.120,80,/close (dependig of the tresshold). It would be better when this wemos only send one command when it reaches the thresshold and one when it falls below the thresshold. Is this possible?

You can have a look at the "level" plugin to implement some kind of hysteresis like behavior.

I read the wiki of this levelplugin but I see it's combined a setpoint with an action on a GPIO (high of low). I don't want to have an action on a GPIO, I want to have a httprequest when the setpoint is reached. I don't read there is a possibility to do something like this?

You can add an event in the rules to achieve what you want, leave the gpio set to none

Code: Select all

on level#output do
  If %eventvalue%=1
    Sendtohttp,.... // 'on' command
  else
    Sendtohttp,.... // 'off' command
  endif
endon
