[Bug] the plugin does not discover Shellys with firmware 1.11.7
**Describe the bug**
I'm using hoobs with the plugin and updated to Hoobs 4 (fully fresh installation) and all shelly are found. Than I updated the shelly firmware to 1.11.7 and hoobs does not discover the Shellys anymore.
After downgrade the Shellys to 0.9.4 everything works fine and hoobs discovers alles Shellys directly.

**Log output**

**Environment:**
 - Shelly device(s): Shelly 1, Shelly plug s, Shelly Dimmer 1, / NOT Shelly DW-2
 - Plugin version: 0.19.1
 - Device running homebridge: Raspberry Pi 4 with Hoobs
