Wanted: ST Arduino Shield

They directed me to their data logger shield.

I recommend giving ESP8266/NodeMCU with Arduino a try, this thread has working example of DH and Arduino code

ESP8266 Node MCU - Temp, Contact, Water Sensor

Let me start by saying I’m not a dev by any means, I just wanted to share what i got working. This is not a tutorial, more like a list of things I used. Over the last few months I have wanted to get my ESP8866’s into smartthings somehow. I’ve read a bunch of posts and didn’t really find anything complete. There’s a thread on here somewhere that I started from. The dev that posted the original code disappeared and I took his posted code and modified it to work for my needs. I made a contact sensor and a water sensor. Both sensors use the same arduino code, but have different device handlers.

NodeMCU boards are $8 on Amazon (this is a small board with micro-usb power and programming). Only drawbacks are (1) ESP only has one A2D/analog input, you could add another chip for that if needed. (2) low power, I don’t know if ESP will work well using a battery. There are articles/blog posts on the net for how to minimize power usage turning off WiFi though. (3) I’m sure there are others depending on what you want to do.

There is also a D1 mini NodeMCU $7 that has stackable addon boards similar to shields.
