Fumee Bleue, I have just built the MySensors Linky with parts you have sent.

It seems to work, but i'm not getting any data from the Linky. Presentation of the children is made, in Domoticz, and most are updated (timestamp) however there is no data! in the values.

I have tested continuity of the solder joints, etc. This is fine.

Is there a setting in the Linky itself that needs to be enable so it sends data?

@zboblamont If you are talking about a swimming pool, the chlorine/salt and other chemicals make for a very corrosive environment. so anything mechanical and electrical will not last long!

I want to make something similar (including, salinity, PH value etc) and have found the following from Adafruit: https://www.adafruit.com/product/3827 (not cheap) but if you want to measure the actual level instead of a max or min level as with floats. it might be of interest.

I have not tried it myself,as my pool automation is way down the list of things to do
