Hi, i’m new with Home assistant and i need your help 
Till now i have been automation with broadlink, alexa and smart life apps. Now i installed HA but i i can not add my sensors and other stuffs. I had 2 door sensors controled by Smart life app, switch and water leak sensor which can not find or add in HA. I tried to find Smart Life from integrations but there is only Tuya.
Also for broadlink i have sensors and switches which again are not shown in Broadling integration, only the device.
In the Alexa app i had all mentioned above devices and sensors but when i linked Alexa with HA and install HACS i was able only to see my three echo devices media players. I watched several videos on youtube but still can’t figure it out.
Can someone tell me where i am wrong ?
