I have a couple storage containers (40’ conex type and a semi trailer) that I’d like to put temperature and humidity sensors inside. Being metal they don’t have reliable wifi signals. I got to thinking a POE ESP device might be ideal, and provide options to monitor the door condition.
My experience with ESP is limited to flashing the S31 plug with ESPHome, but I’d like to try to tackle this.
I’d like to have the temp/humidity sensors, and at least a single door sensor. Perhaps motion and a relay or two down the line.
Does anyone have any suggestions on where to start with hardware?
This is what I found for the esp, but I don’t yet understand why j might buy one version over another or if it’s really suitable. Also, I’d love suggestions for the other components too.
Thank you!
