SeeedStudio SenseCAP T1000-E. It's the size of a credit card so it's easy to set in a window where it would get good signal and it can last three days on a battery with SX-126X RX Boosted Gain disable...
Thanks for the advice..
I can set one up on a remote building so how would this work with a small solar panel ??
