Device SHSW-1 32CD98 is stale. Unregistering its accessories.
Thanks for the great plugin.

Unfortunately, since some days my two shellies (Shelly 1) are unregistered.

Followed the log entries:
[2019-4-13 20:43:22] [Shelly] Device SHSW-1 32C852 is stale. Unregistering its accessories.
[2019-4-13 20:43:24] [Shelly] Device SHSW-1 32CD98 is stale. Unregistering its accessories.

Now the plugin does not find the shellies any more. I have rebooted my raspy and the shellies. I have updated all devices, homebridge and the plugin. I also could ping my shellies from raspy. 

I don’t know what’s happening and I do not know how I can fix this.

I hope you can help me.

My config.json:
   "platforms":[{
        "platform": "Shelly",
        "name": "Shelly",
        "username": null,
        "password": null,
        "networkInterface": "192.168.178.24"
    }]
