Shelly binding. Error by shelly 1 thing: Unable to update status: null (class java.lang.NullPointerException)

Hello, I use openhab 2.5.2 with several shelly’s 2.5 ant their binding 2.5.2. This working great. Now, I use shelly 1 and the status from the thing is always unknown. All other shelly’s 2.5 working fine. I get the following message in openhab.log:

2020-04-25 19:09:59.821 [WARN ] [mmon.WrappedScheduledExecutorService] - Scheduled runnable ended with an exception:

Try uninstalling and reinstalling the binding to see if OH picks up the Shelly 1.

Yes. That was the solution.
I have uninstall and install again the shelly binding.
Now it works great.

Thanks for your support!
