They _do_ have USB functionality, but it would make the whole setup bigger and bulkier.
If size is everything I suppose there's less choice, but a pi zero W seems a lot cheaper.
Size isn't everything, but it is an important factor. I didn't know about the pi zero w, looks neat. I don't think the single cpu is much of an issue, but I wonder about the lack of (possibility for) an external wifi aerial. I do have a Raspberry running too, but wlan reception is pretty good where it is sat. The nanos require an external aerial.

Nice - makes you wonder why they didn't just add that socket.
Pricewise, the pi zero w is 30 with a 24pin header, I might have to take a closer look.
Eh, 30 what? It's £13 or $14 with header, which is 40-pin BTW.
Here it is SFr30 with the 40pin header. Slightly less without :-) The nanopi is slightly more, but includes two headers and an aerial.
Another possibility is to use an Arduino-based board or similar. There are various boards like
Yes - I've seen the solution with ESP8266. A couple of things that keep me away: a) learning curve, lack of experience. b) they don't run Linux The nanopis are really easy to use, they run openSUSE, and I just treat them like any other system (ignoring the SD card issue). I did consider something Arduino-like in the beginning - I wanted to read my electricity meters - it just seemed too much hobby, not enough utility. https://www.jessen.ch/electricity/
Then connect sensors to it and transmit the data to a bigger system somewhere more convenient and store the data there.
Yes, we do that too although up to minute data is available directly from the Nanopi. -- Per Jessen, Zürich (1.9°C) http://www.hostsuisse.com/ - dedicated server rental in Switzerland. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
