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](http://amazon.de) only offers nodemcu, so I think I will buy them [here](https://www.otronic.nl/a-60559521/esp8266/wemos-d1-mini-v3-esp8266-wifi-ch340-development-board/?gclid=Cj0KCQiA6NOPBhCPARIsAHAy2zAwcjBLgeVlqD7tenC5wQQPtEkv5N5Hko-aw8FaLgtE1AcrJinN9JwaAs_hEALw_wcB).

Ok now I finally am getting somewhere...  
Bit off-topic so I will create two separate discussions:

- [Discussion 1](https://discourse.nodered.org/t/ways-to-power-a-large-series-of-wemo-d1-mini-boards/57445): How should I power a large series of those wemo d1 mini devices.
- [Discussion 2](https://discourse.nodered.org/t/wemo-d1-mini-with-wired-ethernet/57447): 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...
