WiFi transmission is unreliable. A sensor needs power anyway.
For (security) cameras my premise already has ethernet cables in place and a PoE (power over ethernet) switch. There are even spare ethernet cables and free ports on the switch.
Wouldn’t it be nice if a sensor.community device is powered and communicates over hard wired ethernet?
ESP32-WROOM-32 with PoE boards are available at Olimex for € 17,95 and a
LilyGO TTGO ESP32-WROOM-32 PoE is priced at € 28,50
Someone also asked for it. Let s talk in january
I would have probably opted for buying a POE ethernet version if that had been an option, although the WiFi seems to be fine.
it’s very interesting me too
Same issue for me.
WiFi outside the buildings is rare, cables are in place.
Is this idea growing right now?
