Hallo,

Can anyone advise what would be the easiest way to connect a waterflow sensor to Homey?  
Sensor itself is just a drycontact switch triggered by the waterflow.  
Appreciate any ideas and sorry if I missed existing solution in the community forum…

So, you want a dry contact sending signals to Homey?  
Consider using a flood sensor. Aqara models have 2 screws which send a signal when submerged in water.  
This also works when you shortcut them by a wire connected to the dry contact.

Hi Peter,  
Even if have found Shelly i4 as well, your proposal sounds better! Thanks! Especially I need it outside… I will make it a trial!
