### TO REPRODUCE
_Steps to reproduce the behavior:_

I have modified the `user_config_override.h` as follow:

ifndef _USER_CONFIG_OVERRIDEH

define _USER_CONFIG_OVERRIDEH

ifndef USE_SCRIPT

define USE_SCRIPT

endif

ifdef USE_RULES

undef USE_RULES

endif

define USE_WEBSEND_RESPONSE

endif // _USER_CONFIG_OVERRIDEH

And then I use this script:

D tvstr="" tvnum=0 res=0 flg=0 S if upsecs%10==0 then ; get contents to http page, directly call section >E when ready flg=1 print call luftsensor ; IP could be either http://192.168.1.39:888/data.json (it's a portmap to port 80 via a wifi repeater) or http://192.168.1.33/data.json ; res=http("192.168.1.39:888" "/data.json") res=http("192.168.1.33" "/data.json") flg=0 endif E if flg>0 then ; extract 4 occurrence of text "value" tvstr=gwr("value" 4) print %tvstr% print "111" ; get rid of " chars at start tvstr=st(tvstr " 2) print %tvstr% print "222" ; convert string to number tvnum=tvstr print %tvnum% print "333" endif

EXPECTED BEHAVIOUR

A clear and concise description of what you expected to happen. I want to use my Tasmota NodeMCU esp8266 to turn ON/OFF my DIY air filter when my Luftdaten sensor is above a certain threshold). The smart plug should connect to my json local url and based on the data in this json (if value of SDS_P1 is above 5 or value of SDS_P2 is above 10), the NodeMCU should switch on and off the air filter.

The json looks like that :

{"software_version": "VV-111-133", "age":"12", "sensordatavalues":[{"value_type":"SDS_P1","value":"6.32"},{"value_type":"SDS_P2","value":"2.70"},{"value_type":"temperature","value":"25.00"},{"value_type":"humidity","value":"58.10"},{"value_type":"samples","value":"4902366"},{"value_type":"min_micro","value":"29"},{"value_type":"max_micro","value":"234874"},{"value_type":"interval","value":"145000"},{"value_type":"signal","value":"-55"}]}

ok, just uploaded a debug version add #define HTTP_DEBUG to user config and report the console messages

Thanks a lot for that! I am not sure what you mean by "debug version" but I download the code from this repo and build it via platformIO and it worked! The value was retrieved. Then I tested with the current Tasmota development which is 9.5.0.8 and the value was also retrieved! I just need to retrieve the second value for SDS_P2 and then to switch the plug on/off based on a threshold. I will then publish the code for the others luftdaten users.

Thanks a lot for your help! You were amazing!
