Septik tank i båten

Bra rykte.
WC fritidsbåt

Jag valde Gobius tankmätare för att avgöra när det var dags att tömma septiktanken i min Nimbus 2600.

Den har faktiskt inte fungerat så bra, skulle behöva er hjälp med att få det att fungera.

I installed 5x gobius pro sensors on waste tank, it was working pretty good last year, but sometimes one sensor was losing connection with bluetooth (phone andorid, ipad) even when the phone/ipad is just 1m away with no walls between. Now this year they don’t show liquid level for most of the time – I tried to recalibrate on empty tank several times and no change.
I generally like the product idea but realibity is far away from expectations – I think that 5 sensors make a lot o problem because even if one loses bluetooth communication I can not executue extra measurement on the app.
I was thinking of getting Gobius-C but after spending 600EUR for Gobius PRO set I dont feel like spending another 350EUR.
How to trouble shoot the problem or exchange it for more realable solution from gobius?
kind regards
