To receive the weather readings from a WH1080 by radio, you can use a SDR USB with a Raspberry Pi 3/4, however it will not work with a Raspberry Pi as it is's power requirements are too high. The SDR USBs draw considerable current from the USB port as they are powering the amplifier.
The appeal of using a Pi Zero is it's low power usage - it is approximately 0.7W (120mA) compare to a Pi 4's 5.1W (1010mA).
So we need another radio receiver. The RFM01 and RFM12b are candidates, and this article describes using them with a Raspberry Pi.
My weather station transmits data on 868Mhz, using Frequency Shift Keying (FSK). This is where a digital '1' is transmitted at one frequency and the '0' at another.
