Read quasi json data from serial port

Hi,

Since many days I’m triying to get datas json from RS485 (serial_sensor) from my heat pump.

My serial sensor

sensor:
  - platform: serial
    serial_port: /dev/ttyUSB1
    baudrate: 15200
    bytesize: 7
    parity: N
    stopbits: 1

My quasi json data:

<99>{
   "dane":{
      "cwu":{
         "D001":3970,
         "D002":3700
      }"co1":{
         "C006":30000,
         "C007":0,
         "C008":3291,
         "C009":2450,
         "C010":61,
         "C046":222,
         "C047":317,
         "C048":3228,
         "C049":30000
      }
   }
}<3>{
   "dane":{
      "dataCzas":{
         "T001":779207,
         "T002":200217,

         "P015":true,
         "P016":true,
         "P018":1,
         "P019":1769,
         "P003":14436587,
         "C051":0
      }"internet":{
         "I001":true,
         "I002":1,
         "I003":0
      }
   }
}<3>{
   "dane":{
      "dataCzas":{
         "T001":779207,
         "T002":200217,
         "T003":310320223
      }"alarmy":{
         "A011":0000000000U,
         "O000":0
      }"co1":{
         "C001":0,
         "C002":false,
         "C003":true,
         "P017":false,
         "P015":true,
         "P016":true,
         "P018":1,

         "P003":14436587,
         "C051":0
      }"internet":{
         "I001":"true",
         "I002":1,
         "I003":0
      }
   }
}

Honnestly, I think I used all the ideas I had and I look forward to any help
