@_elena I’d suggest buy two nodes, so you can tell if it’s working or not. The second one is always going to be useful if you put it somewhere near you and high up. Having two is reassuring when you see it working between the two.
In fact, there’s MeshCore and Meshtastic, it’s worth being on both depending on the exact area (some are more MeshCore, some are more Meshtastic), so really, I’d suggest getting four nodes!
You’ll end up buying more than that in the long run, maybe not all at once in one go.
I also wrote up a page on which nodes I recommend for giving to family members, once you’re into it and can’t stop buying nodes (too early to reveal that?) pikopublish.ing/u0421793/bolg/whichradio.xhtml
