Engine dependencies in package.json
**Describe the bug**
Engine dependencies are set to specific node and homebridge (10.15.3 and 0.4.49) versions.

**To Reproduce**
package.json Line 49..52:

"engines": {                                                        
    "homebridge": "^0.4.49",                                          
    "node": "^v10.15.3"                                               
  },  

**Expected behavior**
Plugin seems to work with homebridge 1.1.0 and node 12.16.3 - may be change the existing ones to minimum version?
