I'm planning to put some sensors in my greenhouse (BME280, soil moisture sensor, ...) to experiment with the collected data.
Problem is that my ESP8266 / ESP32 is having issues with connecting to my Wifi network.
Isn't a greenhouse to be considered to be a Faraday cage, which blocks all signals?
Any idea's on how to improve the connectivity? I've read about turning an ESP32 into a Wifi repeater, might this help? Should I try using LORA boards?
Thanks in advance
