I have 2 HA systems at home, main that connected to almost everything (ZWave / Google Homes / Media Players / Xiaomi Gateways / BlueIris - 20 cams / Vera - too lazy too move everything to Zwave USB attached to main HA and many others),
On the secondary HA I run HA for face recognition only with dlib, it delivers the events through MQTT eventstream and works perfectly,
is there anything I can assist you to set the configuration so it will work for you?
