Client site: 12 sensors across 3 buildings, 200m spread. WiFi does not reach all points reliably.

Weighing:

• WiFi + repeaters: familiar, but repeater maintenance and dead zones
• LoRaWAN + single gateway: 2km range easily covers site, but need gateway + network server (ChirpStack self-hosted)
• ESP-NOW mesh: cheap, but range and mesh reliability questionable at 200m

Leaning LoRaWAN. Low data rate fine for sensor readings (few bytes every few min).

Anyone self-hosted ChirpStack in PH? Gateway hardware recommendation (RAK vs Dragino)? Frequency plan AS923 correct for PH?
