Level indicator/switch

Hi,

Is there a level indicator or level switch that works with sonoff or ewelink app? I need to read the level of a tank and turn off a valve when a certain level is reached.

Thank you

I also wish to have such a device

You can attach an electric water floater to the S1 / S2 inputs of a Sonoff Mini to get the status of the floater.

Hello,
I am looking for a device which measures the water level in a tank and the measured value can then be used in ewelink scenes similarily to e.g. a temperature and humidity sensor. Is there such a device which you can recommend? Thanks.
