Has anyone experience with Sensing Labs devices?

Hi Matt.
It is almost a year since you posted this on the Forum. How did you get on?

I have just received a Sensing-Labs SL-Gateway (Pico) and a TEM-LAB-41NS temperature sensor but I cannot get them working!

I also have an IP68 temperature sensor device but how do you change the battery in that (or is it sealed forever!)

I have struggled with a TTN gateway (lack of support)

I have struggled with a Pi3 gateway

I have had some success with a Multitech Conduit AEP but still difficult and I bought this Sensing Labs one thinking it would be easier but no manuals, no guides, no idea how I configure things

Any help?

Cheers
Rob
