An alternative using 433 MHz send and receive I used about 10 years ago (although it was Arduino based) can be found at
https://www.osengr.org/Projects/Canberra-Wireless-Sensor/Canberra-Wireless-Sensor.shtml
An Aussie by the name of Maurie Daly devised this sensor and used Oshonsoft Basic to send to the base station. You might be able to build the sensors and look at the basic code to implement on a Pico W base and then do the web interface. Likely more work to build and program but it would be compatible with a commercial system (Oregon Scientific - maybe no longer in existence). If you were looking to use more than a couple it might prove to be cheaper as well as provide a learning experience. I built 4 at least and they are still running but to a Windows based application referenced in the link. I have been toying with the idea of providing a web interface but the Window application keeps a log of all readings.
The other side benefit is that an SDR application exists to observe and reports from these 433 Mhz sensors.
Have fun!
