Sensor from url, plain text response

Configuration
1

Hi,
I am trying to integrate sensor data from my Zehnder touch panel, a device that controls temperature regulation in my home.

The data can be read in plain text by reading a certain URL.

Here is an example:
http://192.168.8.49/cgi-bin/getValues.exe?PDP,,R1996,D&PDP,,R1997,D&PDP,,R6,D&PDP,,R1924,D&PDP,,R1923,D&PDP,,DB4030.%40COFF_Registro_Sonda%40,d

and the answer is
2&3&0&657&245&ppo syntax error

657 means 65.7% humidity percentage
245 means 24.5°C

how can I integrate this URL data in a sensor ?

Thanks

If you use a Scrape sensor to get your value you can assign a template to format the data. You will need to figure out what to use for the select variable based on the webpage.

sensor:
  - platform: scrape
    name: zehnder_temp
    resource: http://192.168.8.49/cgi-bin/getValues.exe?PDP,,R1996,D&PDP,,R1997,D&PDP,,R6,D&PDP,,R1924,D&PDP,,R1923,D&PDP,,DB4030.%40COFF_Registro_Sonda%40,d
    select: ?
    device_class: temperature
    state_class: measurement
    unit_of_measurement: '°C'
    value_template: >
      {{ value.split("&")[4][:-1]~"." value.split("&")[4][-1:] }}
  - platform: scrape
    name: zehnder_hum
    resource: http://192.168.8.49/cgi-bin/getValues.exe?PDP,,R1996,D&PDP,,R1997,D&PDP,,R6,D&PDP,,R1924,D&PDP,,R1923,D&PDP,,DB4030.%40COFF_Registro_Sonda%40,d
    select: ?
    device_class: humidity
    state_class: measurement
    unit_of_measurement: '%'
    value_template: >
      {{ value.split("&")[3][:-1]~"." value.split("&")[3][-1:] }}

you give me a good start point, here is the working result

- platform: rest
    name: zehnder_temp
    resource: http://192.168.8.49/cgi-bin/getValues.exe?PDP,,R1996,D&PDP,,R1997,D&PDP,,R6,D&PDP,,R1924,D&PDP,,R1923,D&PDP,,DB4030.%40COFF_Registro_Sonda%40,d
    value_template: >
      {{ value.split("&")[4] | float *0.1 }}

scrape was not right because webpage return plaintext without tag.

Thanks

Good morning,
I’m also importing the values ​​from zhender touch but I don’t understand the logic of the variables called in http…
Can you help me?

First compartment humidity
http://192.168.1.253/cgi-bin/getValues.exe?PDP,,R1924,D

First compartment temperature
http://192.168.1.253/cgi-bin/getValues.exe?PDP,,R1923,D

thanks for the help

well the meaning of variables is a reverse engineering work :rofl: what do you want to read ?

Hi Rodezio,
I would like to read the temperature and humidity values ​​of each room, if possible if it is calling hot or cold.
I would also like to have the on off status of the chiller.

thanks for your help

So for the temperature and humidity here it is

2201 → temperature room 1
2401 → humidity room 1

then increase 01 to 02, 03 and so on for the other rooms.

I don’t have read the state of the TPC output so you have to do it by yourself. It is not difficult to discover the register number.
