Yes Kinda, i want to learn lorawan. Maybe i gonna build an own Gateway later and use some sensors outside in my Garden. I will buy an GSM too as openwrt failover. But Maybe the Router has Problems or idk… I just want an heartbeat from my devices to make sure all is ok, while im not AT home.

Am Shopping list or Tutorial how to build would be great But i cant find. Maybe my search terms are wrong for the lora world
Thank you
