Hello,
I had misunderstood... regarding my issue. Upon checking, I realized that my firewall was not allowing traffic from WISER for KNX to the Ecowitt site. I am updating the code; someone might find it useful or improve it.
This code allows querying the Ecowitt site through APIs with the purpose of acquiring the value from a temperature sensor.
