A while ago I mentioned my plan to be able to monitor my still (alco!) temp from my phone. Well, this now has been accomplished.
I used a wemos D1 mini with DS18B20 temp probe which turned out reasonably easy to get functioning with sketches already available.
For the phone app, I used Blynk and its server. You get to choose from a large variety of widgets to show your data. I just selected a simple gauge to display temp to two decimal places.
You are supposed to be able to create the phone app in a couple of minutes but I struggled to get it working for quite a while and still don't quite know what the problem was. But, yesterday, my dutiful Father's Day son was out and he got it going on his S8 and from then I was able to get it on my S5.
So a bit of a mystery but it works now! Really chuffed with this fun/educational project.
