An ecowitt hub and temperature probe. Works great, integration is 100% local, thank you again @sburke781.

Just holding the baton for those who have gone before.... 
Happy to assist where I can.... slowly starting to appreciate to scale of what I have taken on.....

Which temp probe? Do you have a link?
In the beginning, I wanted to make better cottage cheese than I could get in the grocery store. A couple of months later I had presses, molds, a freezer full of bacteria cultures that probably looks like something out of @aaiyar 's lab, and a large Igloo cooler with an Inova sous vide cooker fitted in it for precise temp. control of eight gallon batches. Needless to say, I have a very understanding wife.

ecowitt has three different water temperature sensors, shown below. All available on Amazon. And they need the ecowitt wifi gateway (about $30) to integrate with Hubitat.

Thanks! Just ordered the WN36. We have a swim spa on order so this will help with monitoring temps and setting up alerts. Much appreciated!

Where were you during the various dryer notification discussions. I bet that ecowitt water probe would work inside a dryer. Would know exactly when the dryer is done based on temp.
It isn't rated to work at those temperatures. Ecowitt's probes are rated for ~140℉. My dryer reaches ~170-180℉. Maybe if I update to one of the newer heat-pump dryers ....
Will I'm sure my sonoff temp/humidity sensor is even more delicate but it's attached to the inside door of my dryer.
Although the more I think about it a probe and whatever is inside the Sonoff are probably different types of temp monitoring tech.
I was recently asked by a friend who runs a series of small - medium retails outlets, to make up a system which would monitor the fridges and freezers in those retail outlets.
Coincidentally, I also noticed the Xfinity rebranding of the Visonic MCT-350, and it's low price on ebay. So, I purchased a few lots.
The real advantage of these sensors is that they can report on a fridge/freezer door open AND if the temperature has risen outside of parameters.
I made up a small Hubitat system with these sensors, and put it into one of his retail establishments.
I even put one into the door of his walk in freezer which has a 5 inch thick metal door.
We shall see if these sensors stand up to the rigors of a small commercial establishment.
I will keep this posted on my progress.
P.S. As a test, I also put these sensors into my home fridges/freezers, and so far they have been reporting accurately and completely, but it's still early.

Interesting, am using them for window open detection but I guess I could also use them for temp averaging / monitoring for the rooms they are in.. 
They are very nice and I bought a few lots myself. Still not sure about battery life though.
Battery life is definitely an issue in a commercial environment.I don't have any idea of how long they will last, but I'm going to check this week to see how they are doing.
I'm not going to take them off from where I put them, because that's also a potential issue. Will they continue to stick in the cold? Who knows. We shall just have to wait and see.
I'll let you know if it works.

Personally I think, longer term, a smart plug with energy monitoring, would likely be a better option for laundry and dryer monitoring, given that you don't need to pay for batteries each 12-18 months in many cases.

Yes and no. I agree that it is a solution that requires less "maintenance".
However, there are still many of us who have dryers that don't have built-in humidity sensors, which can be used to determine when relative humidity is no longer changing, and therefore clothes are dry. With such dryers, like mine, it is possible to waste energy by continuing to "dry" clothes beyond the point that they are dry.
A humidity sensor in the dryer exhaust air-stream is a simple way to evaluate the "dryness" of clothes and be notified - so that drying can be stopped manually (or I guess automatically by cutting power to the dryer). The energy savings can be considerable.
So I can definitely see the value of the solution that @jnosa899 is seeking. But I would implement it differently. I'd stick a probe in the dryer vent, collect temp/hum values to determine the dew point, and stop drying when the dew point changes minimally over ~5 minutes.
Edit: I don't have such a solution, but I am now thinking of implementing it

Good point, I had not considered that aspect of the situation.

How do you get these Brad on Hubitat dashboard??
