LSC Smart Connect Video Doorbell Homekit

Attempt to make the Bell 8S / LSC Smart Connect Video Doorbell fully compatible with HomeKit

Device specifications:

Device name: Smart Home Camera Model: Bell 8S Softwareversion: 2.9.7 Hardwareversion: BE8S_H1_V10_433 Firmwareversion: ppstrong-c51-tuya2_lcs-2.9.7.20201020

Possible HomeKit Configuration:

Accessory (Bell 8S): Video Doorbell

• Doorbell Service (Programmable Switch Button)
• Camera RTP Stream Management Service
• Microphone Service
• Speaker Service (for two-way audio)

Approach to make compatible:

Device runs an app called ppsapp which contains the bell's logic: Streaming video, playing audio, registering events, etcetera.

In order to get a fully working HomeKit doorbell that application needs to either be patched into, modified (keeping the Tuya-side intact) or completely replaced.

Investigating HomeKit Compatability

• Doorbell Service: The state of the doorbell can be retrieved by hooking into the devices's logs.
• Motion Service: The motion detection of the doorbell can be retrieved by hooking into the device's logs
• Camera RTP Stream Management Service: Can be hooked into via RTSP or Onvif
• Speaker Service: Requires modification of ppsapp due to it reserving the connection to the audio device. Two way audio is an entirely different challenge.
• Microphone Service: Unknown at this time.
