What a bunch of useful info... Love you guys 
Only from a scientific point of view of course! So don't get high hopes 
Hey @craigcurtin,
You are right. Those Wemos D1 mini devices are more than enough for my purpose.
Ok I will go for Wemo D1 mini...
Seems that amazon.de only offers nodemcu, so I think I will buy them here.
Ok now I finally am getting somewhere...
Bit off-topic so I will create two separate discussions:
- Discussion 1: How should I power a large series of those wemo d1 mini devices.
- Discussion 2: How can I use wired ethernet on a wemo mini. Because that perhaps limits the firmware that I need to chooce?
Then we can keep this disussion focussed on analog water sensors...
Hope to see some of you guys also in that other discussion 
And how do you install those? Because they seem to have no screw like the pressure sensors, to install them into a tube...
