Dear Arduino Forum,
I've been trying to trigger an ITFFF link via Arduino for quite some time.
The whole thing should switch my Devolo alarm system ON & OFF.
To do this, you can create ITFFF links in Devolo's HomeControl.
They then look like this:
"https://www.mydevolo.com/v1/hc/gateways/<number>/scenes/Alarm_AN?key=<removed>&uuid=<removed>"
Now there is a DEMO script that calls up the Google page with GET on the Arduino and interprets the response.
This script works. "WiFiWebClientSSL" and can be found here:
Arduino Tutorials
If I simply copy this link there, there were register errors.
However, this could be remedied by copying the SSL certificate from mydevolo to the WLAN module of the Arduino UNO R4 (unfortunately only possible with the Nightly IDE or command line at the moment, if anyone wants to reproduce this)
Now my script just does the following:
13:11:52.134 -> SSID: H20global
13:11:52.323 -> IP Address: 192.168.10.100
13:11:52.401 -> signal strength (RSSI):-55 dBm
13:11:52.401 ->
13:11:52.401 -> Starting connection to server...
13:12:02.472 ->
13:12:02.472 -> disconnecting from server.
This means the response is not read or interpreted.
When I check in the Devolo HomeControl Center, the link was not executed at all and the scene was not triggered.
The answer is actually JSON, i.e. I would have to parse JSON as well.
For me, that's only the next step, because the more important thing is that the Arduino triggers the LINK at all, which hasn't happened so far.
Does anyone happen to have a solution for this?
