For anyone else struggling with this I fixed the same problem today!
You need to as thibmaek above my post has said set SSL to false
You also need to set your Home assistant host name without the port 8123. Took me a while to spot that one! As if you have setup SSL properly you no longer specify 8123 when connecting to home assistant as it comes in via 443 and NATs via your router/firewall to 8123.
My Config.json file
{
"bridge": {
"name": "Homebridge",
"username": "CC:22:3D:E3:CE:30",
"port": 51826,
"pin": "***REDACTED***"
},
"description": "This is an example configuration file with one fake accessory and one fake platform. You can use this as a template for creating your own configuration file containing devices you actually own.",
"platforms": [{
"platform": "homebridge-homeassistant.HomeAssistant",
"name": "RossHome",
"host": "https://yourdomain.com (do not specify 8123 as the port)",
"password": "APIKEYREMOVED",
"verify_ssl": false,
"supported_types": ["binary_sensor", "climate", "cover", "device_tracker", "fan", "group", "input_boolean", "light", "lock", "media_player", "scene", "sensor", "switch"]
}]
}
