Useful for farm sensing projects
From 3 comments
Thanks!! It so happens I'm signing on a house on a few acres Monday and want to set up remote soil sensors - this seems like just the thing for coordination.
CalRobert on HNThis looks very cool, and I actually have a farm project right now that could use it.
Sendotsh on HNCool. I think I have some use for this.

'Remote sensing' term is confusing; usually means aerial crop imaging
From 2 comments
Just a tip, in the states the term 'remote sensing' refers to aerial photography of crops either by satellite, airplane or drone. These photos can find problems in the growing…

LoRaWAN jamming and unreliable acks are concerns
From 3 comments
I'm not that deep involved in LoRa but isn't there a problem with it that by spamming the network you can take down the whole one with a $3 device?
tibu on HNIn general LoRa (and LoRaWan) are designed to be very resilient against interference, but targeted jamming seems possible: https://arxiv.org/pdf/1712.02141.pdf On the other hand,…
dbrgn on HNI've played with LoRaWAN and I think that it has one major problem. Limited ack frames. In such case you can not be 100% sure about your data. Symphony link claims that they have…

Integration with farmOS

It would be cool to see this sending data to farmOS running on the Raspberry Pi. farmOS has a nice graphing and mapping UI for assets on farms and I know they have it running on…

Which cheap LoRa radios to buy
From 1 comment
Does anyone know some cheap LoRa radios I can buy? I'd like to play with it, but so far I only know about the LoPy (expensive but easy to program) and some no-name radios for…

Comparison table of LoRa range, speed and power
From 1 comment
Is there any table/matrix to compare basically "for this use that"? Esp in terms of range, speed, bandwidth and power consumption (and maybe licensing?)?

LoRaWAN
From 1 comment
LoRa is awesome technology, if you haven't yet played with it. Here in West Michigan, our city's Board of Public Works runs the local power station, which in turn powers snowmelt…
