Instead of always posting troubles I figured I’d show a successful use case using the WD Dallas 1-wire feature. I struggled to figure out how to get my pool temp displayed and logged for years but figured it out using my already running WD system. I took some 2” pvc pipe and put caps on both ends. Drilled a hole in the end cap and bought a 100mm brewers stainless steel thermowell ($17) to slide a cheap dallas 1-wire chip into.

The water never touches the sensor this way. Just extended the water tubes that were going to my chlorinator anyway so the water now routes into this device and now out to the chlorinator. I used a couple muffler clamps on the pvc so it doesn’t roll around since it’s round.
Ran some cable out to the pool and connected it back to the WD computer. I was already using jpgraphs so just created a couple more for the pool. I also post it to my webcam data for the website. For the data storage I’m using the clientraw file being pushed to my website normally. I have a chron going on the website that hourly grabs the temp and stores it into a file. It’s a bit convoluted but it works so anyone interested let me know and I’ll post the php files. It’s been a year so I’ll have to figure out what I did 
Clearly I’ve gone a bit nuts on this but I think I’m all in for like $20 lol.
It’s been running for over a year now. Brian thanks for a great product and please don’t discontinue the Dallas 1-wire feature
