Several changes in the FHEM module:
- name changes of variable or function was not remembered
- on some installations,(at least on one), a connection was not possible (GA protocol bytes) – this did not matter here… Whatever is different.
- the app could “hang” if the connection was not successful
- added SSID “filter” so that it only works in the own Wifi network
Special thanks to Hendrik, who even gave me Wireshark protocols which led me into the right direction…! Wouldn’t have found it without him (and his patience of testing and testing and…)
