The thermometer is is a Fine Offset WH2/FT007TH. In order to offload the ESP32 it might be better to use a integrated receiver like RFM69 or CC1101 instead of RXB6 simple superheterodyne receiver. However if the ESP32-C3 has enough power for all tasks, the RXB6 will be fine too.
The wireless protocol is documented here:
[login to view URL]
Data needed from sensor:
-Sensor ID (1-8)
-Temperature in celcius with decimal
-Humidity
Defined variables:
-SSID
-Password
-HTTP_POST_URL
-API_KEY
When packet with valid CRC is received:
-Make HTTPS POST: key=test&ch=channel&tmp=temperature&hum=humidity
-Implement timeout for HTTPS POST (so it will not hang if internet is offline)
-Print received data to terminal with result for HTTP POST (OK/ERROR)
Code from [login to view URL] has been tested with an Arduino Uno and it is receiving data correctly using a RXB6 UHF receiver.
Example terminal output from above sketch:

Functions:
Convert sensor id. 0x48=1, 0x49=2, 0x4a=3, 0x4b=4, 0x4c=5, 0x4d=6, 0x4e=7, 0x4f=8
Convert temperature to decimal.
If humidity value from sensor is 255 it should be printed as NIL (no humidity sensor in thermometer).
Example terminal output in new sketch:
ID: 1 | Temperature: 21.1C | Humidity: NIL | Upload: OK
ID: 2 | Temperature: 20.4C | Humidity: 36% | Upload: OK
ID: 3 | Temperature: 20.4C | Humidity: 34% | Upload: OK
ID: 4 | Temperature: 21.0C | Humidity: 37% | Upload: ERROR
ID: 5 | Temperature: 21.2C | Humidity: 39% | Upload: OK
ID: 6 | Temperature: 20.9C | Humidity: 40% | Upload: OK
ID: 7 | Temperature: 21.3C | Humidity: 40% | Upload: OK
ID: 8 | Temperature: 20.6C | Humidity: 40% | Upload: OK
In this example, ID 4 failed because of HTTP post timeout. Packets with bad CRC is not shown.
