Adding Ethernet to "Thing Plus"

Development Boards ESP32
1

Hello Everyone,

I’m trying to sense the water level in my well which is a few hundred feet away from my house, and then post the height on a server hosted on a “Thing Plus” so I can then look at the height before I have a shower (to decide how long I’ve got!).

I’d like to connect my Thing Plus using a ethernet cable, rather than wirelessly. My water sensor is a 24v device so I wanted to send 24v POE as well to power my sensor, and then drop the voltage to also power my Thing Plus.

Can anyone point me in the right direction? I understand that the Thing Plus has ethernet capabilities, but how tricky is it to add that? If you can speak to the POE issue as well it would be greatly helpful. Can I just buy a https://www.sparkfun.com/products/8534 RJ45 Ethernet MagJack and solder it to the board? Seems too easy!

Thanks!

Shawn

I would search the for a bob that had the ethernet and PoE and see what lib it used and try simple test compile to see what happens. Just because a test compile does not give an error does not mean that you wont have problems when loaded on the ESP32.

I start with an edited copy of examples and expand from there. I also copy and paste working programs into larger programs. So on the bench you could use WiFi to get the webpage the way you want it and make sure you are getting good sensor readings before switching to ethernet.

But I am just an old mechanic so what do I know.
