@ritesh-t If you have not already found it you may also benefit from the thread by @zboblamont which can be found here. It addresses some issues of unstable readings that were occurring when the water in the tank was at a lower level.

@zboblamont I would be interested to see your final sketch if you don't mind posting it.

Well done @zboblamont great news to see you have had a win.

The Playing with fusion sketch uses the I2C library found here

some more info on the library here

@unfadingpyro Great to hear you got it all working. Always a good feeling when a project comes together

1.5.4 is a few versions back now so it will help if you post the code you are using, even if it is the standard version. That will give us a starting point to work from.
Also what controller are you using.

Yes i can see your wiring now and no you are not likely to get any sort of reading with that circuit. You have the 712 wired in parallel with the charge wire, it needs to be in series instead. The load needs to be connected to the same side that the charge wire is on. So a quick re-draw of your circuit would look like this.

Don't forget to add a fuse at the battery positive.

The original drawing from earlier in this thread would also be ok

Your only getting 0 sent for the relay so it certainly won't be changing status. Perhaps post the code you are using .

@unfadingpyro I can't see your wiring diagram.

@alexsh1 I ended up using the dust sensor type for both readings. In Domoticz it allows you to set the letters to be used after the number so was easy to just add km to the end.

The original post where using dust was discussed is here
