Reading consumption from web server using php

[danidani 0]

Hi,

 

I would like to crate a simple web page to show summary of energy consumption of previous day.

 

This is my request to HC3:

Please login or register to see this code.

 

This is my simple php page:

Please login or register to see this code.

 

Actually, my php knowledge is very basic, just "learn by example", so I am not sure what exactly is wrong and why I don't get any result.

 

Could you please give me some working example of this?

Thank you!

 

Actually, I am getting this error message:

 

Notice: Trying to get property 'topConsumingDevices' of non-object in /volume1/web/elektro/index.php on line 31 Warning: Invalid argument supplied for foreach() in /volume1/web/elektro/index.php on line 31

Top consuming devices

Name	Consumption

 

If I try the same link in a browser, I got a valid json response. Do you have an idea, what could be wrong?

edit: It looks like I am getting no data from HC3. I don't know why, both user name and password are correct.

IP address?

I used exactly your code and have changed login, password and ip address only:

 

      $login = 'my_admin_user';
      $password = 'my_admin_password';
      $url = 'http://my_ip_address/api/energy/consumption/summary?period=2021-12-11';

 

As a web server I am using Synology Web Station with PHP 7.4.

Ok

insert AFTER line

$json =

die(var_dump($json));

Thank you for your patience. The result is "NULL".

I think it is not a Fibaro issue. I suppose the problem is at Synology side or in the network configuration.

 

edit:

 

I tried this:

And this is the result:

If I try https instead of http in the url then result change:

Any idea, what could be wrong?

 

Both HC3 and Synology are in the same local network.

 

edit 2:

 

If the fibaro url is "hc3-myserialnumber" then the result "bool(false)" is the same for http and https:

After some tests, the problem is in the curl to fibaro (I don't know where).

 

If I try this:

Please login or register to see this code.

I get a valid json data and I am able to parse it.

 

If I modify

Please login or register to see this code.

to anything else (e.g. /api2/ or whatever in the address), the result is still the same "bool(false)".

 

edit:

 

I have tried this syntax aswell, but the result is the same:

https - SSL

curl is not expect selfSigned URL

so do not use https with fibaro API

 

IMHO

Solved, thank you very much! "http" works for me.

 

I had to change Secure Connection settings from https to http/https. Also "hc3-xxxxxxxx" is not correct if it is not registred in local DNS (even if it works in web browser). IP address in the request url is the trick.
