OK, more info then. OLISTO is a bit comparable with IFTTT, but then for free. And with more options. More info about it can be found https://olisto.com/ and in the forum https://forum.olisto.com/. In the openhab forum there is an post from 2019 about integration between the OPENHAB and OLISTO. https://community.openhab.org/t/integration-with-olisto/62295
is about it.
I’m using OPENHAB 4.3.5. Normally if the position of my BLINDS is changing, I was able to use this new location to take actions in OLISTO. As said, a bit the same as IFTTT was doing in the past. As far as I know the communication is using the MYOPENHAB.ORG connection. The authentication is based on OAUTH2.
But in the MYOPENHAB addon, there is still a ENHANCED option that is telling about EXPOSING devices to 3rd party like IFTTT. But if I read the comunity well, this should be working anymore for years. But that doesn’t explain then why it stopped working less then a week ago for me. Is here anywhere in OPENHAB to detect if it is sending out to the outside world the status of my blinds? And even better: Is there anywhere in the MYOPENHAB to see what is going through?
