Hi folks, my system is running again.
Here my system environment: fritzbox 7530, updated to 8.02, DECT200-switch, node-red-contrib-fritzapi v 0.5.2.
I searched the fritzbox-environment and found under "SmartHome/Geräte und Gruppen", aside from my 7 registered DECT-devices ("Status" = OK) an unknown device which was not connected, according to the reading in "Status". I simply removed this device. And that was it!
I could use the fritzapi-nodes, like i did beforehand.
I really do not know, what caused this erroneous entry, nor do I know how it could influence operation. I tried a lot, including the removal of all fritzapi-nodes, deletion and re-installation of the fritzapi-environment, but all in vain.
I hope you can solve your problems as easy as I was able to do it.
Peter
