**Describe The Bug:**
Unable to view or control ThinQ1 air conditioner within Homekit. I have 3 air conditioners:
1. Office Air
2. Bedroom Air
3. Living Room Air

All 3 are the same model number: LG LP1417WSRSM

They're connected to WIFI and accessible/controllable from within the LG ThingQ app.

**To Reproduce:**
1. Install LG Thinq Plugin v1.2.9
2. Click the "Configuration" button
3. Click LG Account
4. Type username
5. Type password
6. Check ThinQ1 Support checkbox
7. Click Save
8. Reboot Hoobs
9. Above logs are generated

**Expected behavior:**
The Lg Thinq Bridge was connected to HomeKit. I expected to see the 3 air conditioners appear within the UI.
