Jeg har prøvet forskellige forsøg med en Gateway opsætning, og på nuværende tidspunkt tester jeg

Transciever RFM95W

ESP 32 TTGO og Raspberry Pi (Afventer LoRa Gateway HAT for Raspberry Pi)

3,6 Volt LiOn Battery

Pi PoE Switch HAT - Power over Ethernet for Raspberry Pi

Charge og controller til Solar panel

Nedenstående kode er testudgaven, som jeg bruger på min Control Receiver
