You can use any Raspberry Pi model with a 40-pin header we chose a Raspberry Pi Zero W for our setup and connected to it via SSH rather than using a monitor for setup. With your Raspberry Pi powered off, mount the Weather HAT on its GPIO header, with the body of the HAT over that of Raspberry Pi. You may also want to change the hostname to something like ‘weather.local’, to make it easier to identify your weather station Raspberry Pi on the network (rather than using its IP address). Here you can enable SSH (useful for remote operation later), set a username and password, and configure your WiFi connection. While you’re at it, click the cog icon in Imager to access the Advanced Options. If you don’t already have a recent version of Raspberry Pi OS written to your microSD card, use Raspberry Pi Imager to do so from another computer. ![]() Alternatively, you may already have similar sensors or be able to source them elsewhere, but you’ll need a couple of RJ11 connectors to plug them into the HAT – with wind speed and direction sensors routed through one connector. The Weather Sensors Kit comprises three meteorological sensors: an anemometer to measure wind speed, a wind vane for direction, and ‘tipping bucket’ rainfall gauge. ![]() ![]() Our weather station’s cables go into the garage where a Weather HAT-equipped Raspberry Pi is located – an external weather-proof box would be better, however
