Ok will do. We may even try the Dragino LSE01 soil moisture sensor for a change.
Our locations are pretty remote ; is there a way to check what might be the impact of the backhaul ?
At least they say so on the last version of the technical data sheet, however i cannot find any trace of them on the LoRa Alliance certified products showcase page. Also, i just noticed on the last TDS the “GEN2” label, we’ll have to check which one Sensoterra provided as this is not specified in our invoice, and also what are the main differences between the two generations.
We don’t have an explicit info about that, Sensoterra’s using an intermediate in-house serial number in between both in their monitoring interface and raw measurement files.
Not much useful on the probes either, the QR code is S/N as well.
I am not in place of putting @Jeff-UK knowledge and experience into question, i was just pointing out these contradictions 
Nope, we hear nothing from them.
Well, it’s gotten a bit difficult now…
The antenna extension was very similar to what has been done by Tnkerman and Disk91, i.e. disconnecting the PCB antenna and connecting a 868 MHz-tuned one via a 5cm UFL to SMA cable.
.
…but this makes sense mainly in the case where all probes send data at the exact same time, right ?
Well, the discussions have been mostly handled by the commercial director, but i can try to be in touch and send specific questions to the proper tech guys.
