Plugin can't read data from LYWSD02MMC #186

Open ndrobac opened 1 year ago

ndrobac commented 1 year ago

It does find the device, the decryption key is added properly, but it gets confused with strange event type number.

Expected Behaviour

Plugin should read the data from device, and decrypt it well, so the info can be properly passed to Homekit.

Current Behaviour

Plugin finds the device, but it can't parse the data properly Accessories show values of 0.

Steps to Reproduce (for bugs)

  1. install the plugin
  2. restart the homebridge
  3. look at the log...

Other notable things

I did try hcitool lescan, and it does list the bluetooth devices via homebridge console, so the bluetooth hardware and hci scanning works. Also tried to run it without entering MAC address, and LE decryption key (finds it, asks for decryption key). Also tried Mijia Thermometer plugin - which gets the first batch of data when initially connects, but then again has same 2 errors like above mentioned.
