=Which Raspberry Pi to buy=
A standard desktop computer consumes at least 200 Watts of power (that is when it is idle, it will increase depending on peripherals attached and any processing being done) all the time it is switched on. A Pi Zero W consumes half a Watt when idle, and
==First make a list of what you need==
*Do you want a wired connection to your hub or router?
** Maybe you are going to update external sites, a wired connection may provide a faster and more dependable communication than a wireless link
** If so, a model including an Ethernet socket is advisable (like
** Remember that if you are operating the pi in headless mode, a wired or wireless connection to your LAN is needed for your other device to communicate with the Pi
*Will your MX need to update a database, feed data to a web site, upload to external sites, or control other devices?
** If so, a model Zero will have to do each task in turn, and you will see some delay in information updates, plus you will need to use a larger time between updates
** If so, a model Three (or Four) will be noticeably faster, and
* What interface does your weather station use?
** If your station communicates to MX via wireless, then you choose a model that supports wireless at the right frequency, all models support basic wireless
** If your station communicates via Ethernet, then either a wired, or wireless, connection is possible
** If your station communicates to MX via USB, then choose between the model 0W with one USB socket, and the model 3B+ with 4 USB sockets depending on whether you might want to use another USB socket ever
** If your station uses another communication port (such as serial interface), then you need the additional components that support that interface
== Now research how the various models relate to your needs ==
