Temp probe to turn solar box pump on

Also i am assuming i could just plug it into a USB plug and have it powered that way?

Yes, You mentioned about server. I thought I also brought up that it is also battery backed up. It can stay alive when your have power outage.

@davidgoderre

Is this more accurate than the smartthings multi sensors?

It should be. I am using Bosch BME280 for temperature, humidity and pressure sensor. This is probably the best sensor there is. My DTH also have offset adjustment if you need to calibrate it further. You would get this out of the box.

In any case, If you find that you still have to use a probe, the sensor has expandable analog pin which you can connect to module like below. (sorry I posted wrong link on initial post).

Then, you can connect to K-Type Thermocouple. There is no coding need it for this route. But, you have to wire pins from module to module. I have the DTH for those to work. Thermocouple can work on extreme tempereature range.

The sensor has serial port that you can use as expansion. If you are looking to venture on Arduino development, you can do something like I just did last weekend.

Best solution for monitoring aquarium water temperature

If you want do a bit of DIY, there is plenty of solution. One solution is using DS18D20. There should be waterproof version. You would need an Arduino to read the sensor. You can take the route of Hubduino to get the data to Hubitat. I personally make my Environment Sensor that is expandable. Coincident over the weekend, I build one probe using an ST32 Arduino. I am testing how long cable can I use. I tested 15 feet cable without issue. I am planning to see if I can get all the way…
