Hello,
I have a similar problem.
Can you check on the Shelly, which serves as your gateway, whether the script is on play or pause?
For me, I have to press play manually, then the script runs for some time (hours?, I still have to test how long).
As long as the script is running, all status changes are sent to Openhab.
At some point the script is paused and then status is no longer passed on.
I can’t say why the script on the Gateway Shelly pauses.
